What do muscle cells during oxygen deprivation gain from the conversion of pyruvate?
A. ATP and lactate.
B. NAD+ and lactate
C. CO2 and lactate
D. ATP and alcohol
E. ATP, lactate, CO2
Correct answer is B, but couldn't A also be a correct answer too.
They clearly mention in the solution that "ATP, NAD+, and lactate are gained by the muscle cell"...so what makes B better than A.
I'd understand chioce B to be correct if they asked "what products are formed from the conversion of pyruvate in oxygen depleted muscle cells?"
However by saying what do the cells gain, is almost like saying "how do they benefit." Yes NAD+ forms, but it goes into making more ATP, so that is what the cell truly gains.
Haha I'm most likely over analyzing this, but if someone could better explain the answer, I'd appreciate it.
