What happens during the Krebs cycle?

ATP and NADH from food are converted to CO2 and O2.

NADH from glycolysis is converted to ATP and O2 molecules.

Glucose is broken down in a cycle of reactions to form pyruvate.

Pyruvate is broken down in a series of reactions to form CO2.

anonymous · Answer

yea it A

frostbite · Answer

A would be ETC.
C glycolysis.

50% chance of hitting right now.

frostbite · Answer

It is:
"Pyruvate is broken down in a series of reactions to form CO2."
The CO2 releasing processes are called "xidative dcarboxylation"

frostbite · Answer

oxidative decarboxylation*

frostbite · Answer

Well remove the fact it is a cycle and NADH along with FADH2 is gone + we start acetyl-CoA then we are almost there @abb0t :P

abb0t · Answer

Going by the given answers, I'm saying that the choices provided none look correct to me.

anonymous · Answer

lol the answer was D you guys

abb0t · Answer

Cool story, bro.

frostbite · Answer

Well what I said... however I got the feeling that @abb0t isn't satisfied then you hardly get a "real" picture of the cycle.
