Question

Glycolysis provides a cell with a net gain of

A. 2 ATP molecules.

B. 4 ATP molecules.

C. 18 ATP molecules.

D. 36 ATP molecules.

Answer 1

I think to be precise, as far as i remember, after glycolysis in the presence of oxygen, 38 ATP molecules are generated and in the absence of oxygen, 2 ATP molecules are generated.

Answer 2

Answer 3

thanx

Answer 4

After glycolysis only 2 ATP is created, the rest come from Kreb's cycle and the oxidative phosphorylation.

In the glycolysis we have investing phase and gain phase. In the investing phase we use 2 ATP and in the gain phase we get 4 ATP back.. so the net ATP gained is 2 ATP.
