2 ATP
Glycolysis uses 2 ATP molecules in the first half, called the Energy Investment Phase, and creates 4 ATP molecules in the second half, the Energy Payoff Phase. So -2 + 4 = a net gain of 2 ATP molecules.

∙ 11y agoThe net gain is 2 ATP. You use up 2 ATP in glycolysis, but also produce 2 ATP of each pyruvate. Since there are 2 pyruvate, glycolysis produces 4 ATP, and uses up 2 ATP, amounting to a net gain of 2 ATP.

In glycolysis for each molecule of glucose oxidized to pyruvate?
2 molecules of ATP are used and 4 molecules of ATP are produced.
How many Krebs cycle occur per glucose?
twice
During glycolosys glucose molecules is broken into?
In glycolysis, one 6-carbon glucose molecule is converted into two 3-carbon pyruvate molecules. If no oxygen is present then each of those two pyruvate molecules will be converted into 3-carbon lactate (lactic acid).
What is the net ATP yield per glucose during glycolysis?
Gross yield of ATP during glycolysis: 4Net yield of ATP during glycolysis: 2 (anaerobic glycolysis of a glucose molecule took 2 ATP to accomplish so subtract 2 ATP from your gross yield of 4...therefore it's 2 for net yield).Kreb cycle: produces a total of 2ATP (one each time it happens and it happens twice).
Does glycolysis require co-enzymes?
Yes. Glycolysis requires the input of 2 ATP molecules for each molecule of glucose. However, 4 ATP molecules will be produced directly from glycolysis for each molecule of glucose. Therefore, the net ATP yield of glycolysis is 2 ATP.
Is any co2 produced during glycolysis?
Yes. Two carbon dioxide molecules for each molecule of glucose entering glycolysis.
For each molecule of glucose how many times does the Krebs cycle occur?
The Krebs cycle runs twice to break down one molecule of glucose.
In glycolysis for each molecule of glucose oxidized to pyruvate?
2 molecules of ATP are used and 4 molecules of ATP are produced.
How many acetate groups are produced from one glucose during cellular respiration?
Each glucose molecule is converted to two molecules of pyruvate through glycolysis. Each molecule of pyruvate can then be converted to 1 acetyl CoA for a total of 2 acetly groups from 1 glucose
How many Krebs cycle occur per glucose?
twice
How many times does the kreb cycle occur for each molecule of glucose consumed?
twice
How much ATP energy is invested in glycolysis?
2 ATP molecules are invested during glycolysis per each glucose molecule that is being metabolized. The first ATP molecule intervenes in the very first step, that is: from glucose to glucose 6-phosphate, catalyzed by a hexokinase, releasing an ADP molecule. The second ATP molecule is used in the third step: from fructose 6 phosphate to fructose 1,6-bisphosphate, catalyzed by a phosphofructokinase, and releasing also an ADP molecule.
During glycolosys glucose molecules is broken into?
In glycolysis, one 6-carbon glucose molecule is converted into two 3-carbon pyruvate molecules. If no oxygen is present then each of those two pyruvate molecules will be converted into 3-carbon lactate (lactic acid).
True or false The total amount of ATP that a cell gains for each glucose molecule that enters glycolysis depends on the presence of carbon dioxide?
False. It depends on oxygen.
How is glucose changed as it moves through glycolysis?
Glucose is modified by particular reactions, and eventually splits into 2 3 carbon sugars, which interconvert between each other. These are modified further to produce pyruvate. Glycolysis literally means, "splitting sugars".
What is the net ATP yield per glucose during glycolysis?
Gross yield of ATP during glycolysis: 4Net yield of ATP during glycolysis: 2 (anaerobic glycolysis of a glucose molecule took 2 ATP to accomplish so subtract 2 ATP from your gross yield of 4...therefore it's 2 for net yield).Kreb cycle: produces a total of 2ATP (one each time it happens and it happens twice).
What happens during glycolysis in cellular respirationg?
1 molecule of glucose (6c) -------> glucose -6-phosphate ---->fructose-6-phosphate----->fructose1-6-diphosphate------->2PGAL molecules (3c each ) -------> 2 pyruvic acid molecules ( 3c each ) ------> krebs cycle
