How does oxidizing agent work?

An oxidizing agent accepts electrons and becomes reduced, while a reducing agent shares electrons to be oxidized. The NADH produced in the cytoplasm through glycolysis is transferred to the mitochondria by mitochondrial shuttles. It is used to reduce the mitochondrial NAD+ into NADH.

What is the process of cellular respiration?

Cellular respiration is the enzymatic breakdown of glucose (C6H12O6) in the presence of oxygen (O2) to produce cellular energy (ATP): 1. Glycolysis: (Fig. 18-2) a ten-step process that occurs in the cytoplasm converts each molecule of glucose to two molecules of pyruvic acid (a 3-carbon molecule) an anaerobic process - proceeds whether or not O2 is present ; O2 is not required net yield of 2 ATP per glucose molecule net yield of 2 NADH per glucose (NADH is nicotine adenine dinucleotide, a co-enzyme that serves as a carrier for H+ ions liberated as glucose is oxidized.) The pyruvic acid diffuses into the inner compartment of the mitochondrion where a transition reaction (Fig. 18-3) occurs that serves to prepare pyruvic acid for entry into the next stage of respiration: (a) pyruvic acid ® acetic acid + CO2 (a waste product of cell metabolism) + NADH+ (b) acetic acid + co-enzyme A ® acetyl CoA 2. Citric Acid or TCA Cycle: (Fig. 18-3) occurs in the inner mitochondrial matrix the acetyl group detaches from the co-enzyme A and enters the reaction cycle an aerobic process; will proceed only in the presence of O2 net yield of 2 ATP per glucose molecule (per 2 acetyl CoA) net yield of 6 NADH and 2 FADH2 (FAD serves the same purpose as NAD) in this stage of cellular respiration, the oxidation of glucose to CO2 is completed 3. Electron Transport System: consists of a series of enzymes on the inner mitochondrial membrane electrons are released from NADH and from FADH2 and as they are passed along the series of enzymes, they give up energy which is used to fuel a process called chemiosmosis by which H+ ions are actively transported across the inner mitochondrial membrane into the outer mitochondrial compartment. The H+ ions then flow back through special pores in the membrane, a pr Continue reading >>

What is the most pressing need of all cells in the body?

The most pressing need of all cells in the body is for an immediate source of energy. Some cells such as brain cells have severely limited storage capacities for either glucose or ATP, and for this reason, the blood must maintain a fairly constant supply of glucose. Glucose is transported into cells as needed and once inside of the cells, the energy producing series of reactions commences. The three major carbohydrate energy producing reactions are glycolysis, the citric acid cycle, and the electron transport chain. The overall reaction of glycolysis which occurs in the cytoplasm is C6H12O6 + 2 NAD+ + 2 ADP + 2 P -----> 2 pyruvic acid, (CH3 (C=O)COOH + 2 ATP + 2 NADH + 2 H+ The major steps of glycolysis are outlined in the graphic on the left. There are a variety of starting points for glycolysis; although, the most usual ones start with glucose or glycogen to produce glucose-6-phosphate.

How Do Organisms Generate Energy?

Enzymes of Glycolysis Yeast 20, J.A. Barnett, A history of research on yeast 6: the main respiratory pathway, 1015-44 (2003). All cells need energy, which they get through ATP, an inherently unstable molecule that must continually be produced. Though ATP can be produced in different ways, nearly all living cells can harness ATP through glycolysis, the stepwise degradation of glucose, and other sugars, obtained from the breakdown of carbohydrates without the need for molecular oxygen (anaerobic). Glycolysis is an ancient, universal pathway that probably developed before there was sufficient oxygen in the atmosphere to sustain more effective methods of energy extraction. When aerobic organisms evolved, they simply added more efficient energy extraction pathways onto glycolysis, breaking down the end products from glycolysis (pyruvate) still further through the tricarboxylic acid cycle. Yet, aerobic cells can still rely predominantly on glycolysis when oxygen is limiting, such as in hard working muscle cells where glycolysis ends in the production of lactate, causing muscle fatigue. The aerobic and anaerobic processes are kept separate in eukaryotic cells, with glycolysis occurring in the cytoplasm, and the aerobic tricarboxylic acid cycle occurring in the mitochondria. Glycolysis During glycolysis, glucose is broken down in ten steps to two molecules of pyruvate, which then enters the mitochondria where it is oxidised through the tricarboxylic acid cycle to carbon dioxide and water. Glycolysis can be split into two phases, both of which occur in the cytosol. Phase I involves splitting glucose into two molecules of glyceraldehyde-3-phosphate (G3P) at the expense of 2 ATP molecules, but allows the subsequent energy-producing reactions to be doubled up with a higher net gain Continue reading >>

How does ATP work?

In oxidation, the electrons are stripped from a glucose molecule to reduce NAD+ and FAD . NAD+ and FAD possess a high energy potential to drive the production of ATP in the electron transport chain . ATP production occurs in the mitochondria of the cell. There are two methods of producing ATP: aerobic and anaerobic . In aerobic respiration, oxygen is required. Oxygen plays a key role as it increases ATP production from 4 ATP molecules to about 30 ATP molecules. In anaerobic respiration, oxygen is not required. When oxygen is absent, the generation of ATP continues through fermentation.There are two types of fermentation: alcohol fermentation and lactic acid fermentation . There are several different types of carbohydrates : polysaccharides (e.g., starch , amylopectin , glycogen , cellulose ), monosaccharides (e.g., glucose , galactose , fructose , ribose ) and the disaccharides (e.g., sucrose , maltose , lactose ). Glucose reacts with oxygen in the following redox reaction, C6H12O6 + 6O2 6CO2 + 6H2O, Carbon dioxide and water are waste products, and the overall reaction is exothermic . The breakdown of glucose into energy in the form of molecules of ATP is therefore one of the most important biochemical pathways found in living organisms. Glycolysis , which means sugar splitting, is the initial process in the cellular respiration pathway. Glycolysis can be either an aerobic or anaerobic process. When oxygen is present, glycolysis continues along the aerobic respiration pathway. If oxygen is not present, then ATP production is restricted to anaerobic respiration . The location where glycolysis, aerobic or Continue reading >>

How do cells get energy?

Just like we need energy to get through the day, individual cells need energy for survival too. Cellular respiration is the process by which cells get their energy in the form of ATP. There are two types of cellular respiration, aerobic and anaerobic. Aerobic respiration is more efficient and can be utilized in the presence of oxygen, while anaerobic respiration does not require oxygen. Many organisms (or cells) will use aerobic respiration primarily, however, if there is a limited oxygen supply they can utilize anaerobic respiration for survival. Although there are some organisms (or cells) that always require anaerobic respiration and others that will always require aerobic respiration. Anaerobic respiration has fewer steps, so lets start there. The first step in both anaerobic and aerobic respiration is called glycolysis . This is the process of taking one glucose (sugar) molecule and breaking it down into pyruvate and energy (2 ATP). We will discuss this in depth during aerobic respiration. The second step in anaerobic respiration is called fermentation. Fermentation starts with pyruvate (the end product of glycolysis). Depending on the organism, pyruvate can either be fermented into ethanol (a fancy name for alcohol) or lactate (lactic acid). Fermentation releases CO2, but does not make any ATP all ATP during anaerobic respiration is produced during glycolysis. Since glycolysis produces 2 ATP, anaerobic respiration yields 2 ATP for every molecule of glucose. Both glycolysis and fermentation take place within the cytosol/cytoplasm of a cell. In fact, the entire process of anaerobic respiration takes place in the cytosol. Fermentation is the process by which we make wine and other types alcohol. Through an anaerobic process, yeast will break down the glucose in the Continue reading >>

What is the first step in the respiratory system?

Glycolysis, literally meaning "to split sugar," is the initial step in any respiratory system. Glycolysis involves the breaking down of a sugar (generally glucose, although fructose and other sugars may be used) into more manageable compounds in order to produce energy. The net end products of glycolysis are two Pyruvate , two NADH , and two ATP (A special note on the "two" ATP later). Glycolysis is a process that all organisms undergo; and therefore the most fundamental and primitive of all energy production systems. Glycolysis is a series of steps cells go through to transform sugar into energy that the cell can use. All cells are equipped to perform glycolysis, as it is the primary method cells make energy. The byproducts of glycolysis may be further digested to release more energy. glycosis occurs in the cytoplasm of a cell in a plant. glycosis is the first stage in Respiration. Glycolysis occurs in the cytoplasm of a cell after glucose is ingested through the process of phagocytosis, or "cell eating," in which the cell engulfs a solid compound. Once the glucose is inside the cytoplasm, one molecule of ATP splits and transfers a phosphate group to the glucose, or "phosphorylates" it, so that it becomes an ion which cannot leave the cell because the cell membrane is impermeable to ions. This step effectively allows cells to efficiently absorb and utilize glucose and keep any glucose molecules from escaping. The process of phosphorylation also makes the glucose chemically reactive. Once the glucose has been phosphorylated, it is called "Glucose-6-Phosphate," which will be abbreviated G6P. The G6P is rearranged into Fructose-6-Phosphate (F6P) by a protein. When the F6P is created, another ATP molecule splits and the F6P is phosphorylated by another phosphate group. Th Continue reading >>
