How many steps in glycolysis have ATP as a substrate or product? a. 0 b. 1 c. 2 Epimerase b. Isomerase c. Mutase d. Dehydrogenase e. ligase d. 4 e. 6 2. The step that commits the cell to metabolize glucose is catalyzed by a. Aldolase b. Enolase c. …
Learn more about the 10 steps of glycolysis below. Step 1 The enzyme hexokinase phosphorylates or adds a phosphate group to glucose in a cell's cytoplasm. In the process, a phosphate group from ATP is transferred to glucose producing glucose 6-phosphate or G6P. One molecule of ATP is consumed during this phase. Step 2
Step 1: Enzyme: Hexokinase/glucokinase, Substrate (with ATP cofactor): Glucose, Product: Glucose 6-phosphate, Reversible: No 2nd step glycolysis: What enzyme? Substrate/Product?
Corn is the only source of biofuels b. Biofuels are related to glycolysis because fermentation is an end process of anaerobic glycolysis c. Corn, wood, animal dung, and many other products can produce biofuels d. Many carbohydrate sources can produce ethanol. A . …
A net of two ATP molecules are produced through glycolysis (two are used during the process and four are produced.) Learn more about the 10 steps of glycolysis below.
Glycolysis takes place in the cytoplasm. There are 10 enzymes involved in breaking down sugar. The 10 steps of glycolysis are organized by the order in which specific enzymes act upon the system. Glycolysis can occur with or without oxygen. In the presence of oxygen, glycolysis is the first stage of cellular respiration.
Glycolysis, which translates to "splitting sugars", is the process of releasing energy within sugars. In glycolysis, a six-carbon sugar known as glucose is split into two molecules of a three-carbon sugar called pyruvate. This multistep process yields two ATP molecules containing free energy, two pyruvate molecules, two high energy, ...
In the presence of oxygen, glycolysis is the first stage of cellular respiration. In the absence of oxygen, glycolysis allows cells to make small amounts of ATP through a process of fermentation. Glycolysis takes place in the cytosol of the cell's cytoplasm.
The kinase phosphofructokinase uses another ATP molecule to transfer a phosphate group to F6P in order to form fructose 1,6-bisphosphate or FBP. Two ATP molecules have been used so far.
First, it dehydrogenates GAP by transferring one of its hydrogen (H⁺) molecules to the oxidizing agent nicotinamide adenine dinucleotide (NAD⁺) to form NADH + H⁺.
The enzyme phosphoglycerokinase transfers a phosphate from BPG to a molecule of ADP to form ATP. This happens to each molecule of BPG. This reaction yields two 3-phosphoglycerate (3 PGA) molecules and two ATP molecules.
