Why does ATP production and oxygen consumption increase as the initial NADH concentration increases?
a. More NADH provides more electrons to the electron transport chain, which results in more H⁺ being avalable for chemiosmosis.
b. ATP production and oxygen consumption are always high regardless of initial NADH concentration.
c. More NADH provides fewer electrons to the electron transport chain, which results in fewer H⁺ being avalable for chemiosmosis.
d. There is a correlation between NADH concentration and ATP production, but it is not a causal relationship.
