What happens to pyruvate molecules formed in glycolysis in the absence of oxygen?

Question

anonymous · Answer

likelihood is, you've already experienced what happens firsthand.
have you ever exercised vigorously and started to feel sore in your body?
in humans, pyruvate is converted into lactic acid instead of forming Acetyl-CoA and following into the tricarboxylic cycle (Krebs Cycle). it's called anaerobic respiration.
here, 2 ATP are made per glucose molecule.
since lactic acid still has much energy left to be extracted, it is transported to the liver and converted back into pyruvate.

(a) they will enter the krebs cycle.
(b) they will undergo the process of fermentation.
(c) they will move directly to the electron transport chain.

so witch one is the answer?

A i think

shrutipande9 · Answer

as rightly said by @cowgirlcrazy66 it forms lactate. but it also forms alcohol in some bacteria and yeast....

aaronq · Answer

just to be clear, when you reduce pyruvate to lactate (via NADH) you don't make any ATP. The process merely allows for glycolysis to continue.
