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.
The 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.
Glycolysis produces a net gain of what ATP molecules. ATP is commonly used as storage for cellular energy which is later released and broken down for various cellular activities.
The net gain of energy from glycolisis is?
2
These are produced by substrate level phosphorilation. Net gain is two as two is used
Glycolysis results in a net gain of two molecules of ATP for each molecule of glucose.

4 ATP -2 ATP used 2 ATP made!
2 ATP net
2 molecules of ATP are used and 4 molecules of ATP are produced.

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).
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).
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.
Yes. Two carbon dioxide molecules for each molecule of glucose entering glycolysis.
The Krebs cycle runs twice to break down one molecule of glucose.
2 molecules of ATP are used and 4 molecules of ATP are produced.
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

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.
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).
False. It depends on oxygen.
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".
