How many ATP molecules are produced by the electron transport chain by glycolysis?

Answer 1

A net of two ATP are produced during glycolysis.

Answer 2

First of all, the electron transport chain DOES NOTproduce ATP by glycolysis. Glycolysis takes place outside the mitochondrion (plural: mitochondria), in the cytoplasm. The electron transport chain is located inside of the mitochondrion.

The following does not have anything to do with cellular respiration in prokaryotes.

4 ATP molecules are produced by glycolysis.

34 ATP molecules are produced by the electron transport chain.

2 ATP molecules are used to force the 2 pyruvic acid molecules into the mitochondrion, since it is against the concentration gradient (going from low to high instead of high to low), using a form of active transport (uses energy; opposite is passive transport).

Steps of AEROBIC Cellular Respiration:

1) Glycolysis occurs in the cytoplasm creating 4 ATP molecules. It transforms parts of the glucose molecule into 2 pyruvic acid molecules.

2) The 2 pyruvic acid molecules are forced into the mitochondrion (further descibed above) by using 2 ATP molecules.

3) Acetyl-CoA is derived from the pyruvic acid molecules

4) The Acetyl-CoA goes into the Kreb's Cycle, or the Citric Acid Cycle, and forms 4 more ATP (total produced so far :8 ATP; net produced so far:6ATP)

5) It then goes into the electron transport chain and goes through oxidative phosphorylation and produces 34 ATP.

SO:(for AEROBIC RESPIRATION)

C6H12O6+6O2+2 ATP -------> 6CO2+6H2O+38 ATP

(glucose+oxygen+energy -----(enzymes (ATPase))-----> carbon dioxide+water (dihydrogen oxide)+energy)

The net gain of ATP is 36 ATP. (38 ATP (produced) - 2 ATP (used) = 36 ATP (net gain))

Answer 3

34 produced in Electron transport chain
4 produced in glycolysis (2 net gained, because two taken in four produced)


30 more ATP molecules produced in the electron transport chain then in glycolysis.

Answer 4

Four ATP molecules are produced, but there is a net gain of two. 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.

Answer 5

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..

Answer 6

There are 2 ATP molecules in glycolysis. by: T.Swinson

Answer 7

There are four ATP molecules but two are used, making a net production of two in the end.

Answer 8

Glycolysis produces 2 ATP.

Answer 9

36
