in aerobic organisms, for every 2 glucose catabolized, two kreb cycles must be undertaken. True or False?

Answer 1

False. One glucose enters glycolysis. That glucose is then converted to 2 pyruvate which then go onto become Acetyl CoA to enter the Kreb cycle. The Kreb cycle then spins twice creating CO2, 2-ATP, and 6-NADH & 2 FADH. These protons are then sent to the electron transport chain to produce ATP.

Answer 2

That is false, because for every glucose, 2 pyruvate is formed thus resulting in two turns of the krebs cycle for one glucose. Therefore, there is 4 turns to the krebs cycle for 2 glucose.

Answer 3

False, 2 Krebs cycles per glucose, so in this question 4 would be the correct answer.

Answer 4

False
