For each glucose that enters glycolysis, _____ nadh enter the electron transport chain.
SIZIF [17.4K]
The answer is 10 NADH.
For each glucose molecule that enters glycolysis, a total of 10 NADH are produced.
That is; during glycolysis 2 NADH are produced, while another two are produced in the conversion of pyruvic acid to acetyl-CoA, and in the Citric acid Cycle 6 NADH are produced, that makes a total of 10 NADH, which are then taken to the electron transport chain to produce ATP.

Answer. The most appropriate statement that is explaining the effect and cause during muscle contraction is. “The release of calcium ions causes myosin and actin to attach to each other.” The activation of muscles helps in the generation of muscles that send out the signals to the neurons.
