Question

Which three of the following statements are TRUE?

ATP synthase is essentially a nanomachine – it uses a motor-like, spinning mechanism to produce ATP

Because glucose is split into two molecules of pyruvate the actual ATP yield from glucose breakdown should be doubled to 76

The theoretical yield of ATP from glucose is reduced from 38 to around 30 because of transport processes and energetic losses that will reduce the proton gradient

ATP and NADH are both used for other reactions that take place in the cell

Because of the energy stored in NADH, ATP is not really required for cellular reactions and will eventually disappear from cells in the course of evolution

Explanation / Answer

The statements 1,3 and 4 are correct.Statement 2 is incorrect because only 2 ATP s are produced in glycolysis when glucose is converted to pyruvic acid.
