when NAD+ become NADH, and FAD become FADH they are acting as electron acceptors. ETC takes all the electron acceptors from both glycolysis and the krebs cycle and converts them to.....

Reactions 6 and 9 are coupled with the formation of ATP. To be exact, 2 ATP are produced at step 6 (remember that the reaction occurs twice) and 2 more ATP are produced at Step 9. The net production of visible ATP is: 4 ATP.

Reaction 5 is an oxidation where NAD + removes 2 hydrogens and 2 electrons to produce NADH and H + . Since this reaction occurs twice, 2 NAD + coenzymes are used. If the cell is operating under aerobic conditions (presence of oxygen), then NADH must be reoxidized to NAD + by the electron transport chain.

There are two net molecules of ATP produced by substrate-level phosphorylation during glycolysis. (when one molecule of glucose is respired). Two are used to convert the glu … cose molecule to fructose, but four are released when pyruvate is made. However, the other products of glycolysis enable the Link Reaction, Krebs cycle and Oxidation Phosphorylation to happen, and these release a lot of ATP. 3 people found this useful.

Confidence votes 106. it produces 4 ATP molecules but then uses 2 ATP molecules to break down glucose... so really the net gain of ATP molecules is 2..

ATP is required at Steps 1 and 3. The hydrolysis of ATP to ADP is coupled with these reactions to transfer phosphate to the molecules at Steps 1 and 3. These reactions evidently require energy as well. You may consider that this is a little strange if the overall objective of glycolysis is to produce energy.

Glucose with 6 carbons is split into two molecules of 3 carbons each at Step 4. As a result, Steps 5 through 10 are carried out twice per glucose molecule. Two pyruvic acid molecules are the end product of glycolysis per mono-saccharide molecule.

Introduction to Glycolysis: 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.

This is because the process requires an initial input (energy investment) of 2 ATP molecules in the beginning, … when 2 ATP are converted to 2 ADP.
