Cellular respiration occurs in both eukaryotic and prokaryotic cells, with most reactions taking place in the cytoplasm of prokaryotes and in the mitochondria of eukaryotes. There are three main stages of cellular respiration: glycolysis, the citric acid cycle, and electron transport/oxidative phosphorylation.
Full Answer
There are three main stages of cellular respiration: glycolysis, the citric acid cycle, and electron transport/oxidative phosphorylation. Glycolysis literally means "splitting sugars," and it is the 10-step process by which sugars are released for energy.
The third phase of cellular respiration denotes the Electron Transport chain. Electron Transport Chain implies a group of electron transporters and systems that move from an electron donor to electron acceptors in the center of the mitochondrial membrane.
Cellular respiration is a process by which cells harvest the energy stored in food. It includes glycolysis, the citric acid cycle, and electron transport.

1 Answer. BRIAN M. The three main stages of cellular respiration (aerobic) would include Glycolysis in the cytoplasm, the Kreb's Cycle in the Mitochondrial Matrix and the Electron Transport Chain in the Mitochondrial Membrane.
In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts. The three stages of aerobic cellular respiration are glycolysis (an anaerobic process), the Krebs cycle, and oxidative phosphorylation.
In general, cellular respiration can be divided into four stages: Glycolysis, which does not require oxygen and occurs in the mitochondria of all cells, and the three stages of aerobic respiration, all of which occur in mitochondria: the bridge (or transition) reaction, the Krebs cycle and the electron transport chain ...
The reactions of cellular respiration can be grouped into three stages: glycolysis (stage 1), the Krebs cycle, also called the citric acid cycle (stage 2), and electron transport (stage 3). Figure below gives an overview of these three stages, which are further discussed in the concepts that follow.
The 3 phases of cellular respiration are Glycolysis, the Krebs Cycle, and the Electron Transport Chain.
the cytoplasmGlycolysis takes place in the cytoplasm. Within the mitochondrion, the citric acid cycle occurs in the mitochondrial matrix, and oxidative metabolism occurs at the internal folded mitochondrial membranes (cristae).
While most aerobic respiration (with oxygen) takes place in the cell's mitochondria, and anaerobic respiration (without oxygen) takes place within the cell's cytoplasm.
The energy is stored in the form of ATP. This final process of cellular respiration takes place on the inner membrane of the mitochondria.
Grand Finale. The electron transport chain is the third and final step of cellular respiration. It is the grand finale in which water is formed, along with the majority of ATP needed to power cellular life. It starts with NADH and FADH2 transporting protons through the cell, creating ATP through a series of reactions.
Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.
The Krebs Cycle uses 2 Acetyl CoA (each with 2 carbons), a 4-carbon acceptor molecule that powers the cycle, 8 NAD+ and 2 FAD that will become electron carrier molecules, and 2 ADP + P that will become 2 ATP, and 6 O2 that provide necessary oxygen ( remember, Krebs Cycle is aerobic)
The electrons from the electron carrier molecules hop down the electron transport chain and the H+ ions from the electron carrier molecules to go across the inner membrane through active transport , then they charge back out through facilitated diffusion through the ATP synthase
If the cell has access to oxygen (aka is in an aerobic environment), then the 2 pyruvic acids will become Acetyl CoA and go inside the mitochondria to perform the Krebs cycle for more ATP
The ETC makes 34 ATP (30 from 10 NADH, 4 from FADH2), returns the electron acceptor molecules (10 NAD+ and 2 FAD) so that they can be used again in cellular respiration, and combines the H+ ions with electrons and oxygen atoms to make 6H2O
Cellular Respiration gives both plant and animal cells the useable energy, aka ATP, that they need to do stuff. This is the overall equation:
Steps of cellular respiration 1 (Glycolysis): Steps of cellular respiration 2 (Krebs cycle or Citric Acid Cycle): Steps of cellular respiration 3 (Electron Transport Chain): Catabolism of proteins, fats, and carbohydrates in the 3 steps of cellular respiration.
Cellular respiration plays an important role in releasing the energy to break down glucose to make ATP (Adenosine Triphosphate). Adenosine Triphosphate, also knew as, ATP is an organic compound, which provides energy in living cells in the body. In this process, each molecule of glucose makes 38 molecules of ATP. Here is the equation below:
A glucose molecule split by the enzymes and forms into two- molecules of pyruvate as known as pyruvic acid. When the two molecules of pyruvate formed, the energy released four molecules of ATP and the two-electron carriers NADH (Nicotinamide Adenine Dinucleotide + Hydrogen) made.
Glucose plays a vital role in the Glycolysis, the Krebs cycle, ETC (Electron Transport Chain). One molecule of glucose can potentially cause 38 molecules of ATPs from cellular respiration .
Furthermore, these reactants will transfer the electrons from the electron carrier molecules from high to low transport chain by using active transport. The NADH and FADH2 discharged highly potential energy electrons. On the other hand, the electron transport chain is from the central membrane of the mitochondrion, which occupied the high potential energy electrons along the way.
Now, you might have a few questions about living things. Living things make use of this energy by a process called cellular respiration. Cellular respiration plays an important role in releasing the energy to break down glucose to make ATP (Adenosine Triphosphate).
Two molecules of ATPs need splitting glucose molecule and the two-electron carrier molecules are 2NAD+ (nicotinamide adenine dinucleotide). Next, four molecules of ADP+P (Adenosine Diphosphate) will become four ATP molecules.
