Question

the mitochondrion is host to which portion of cellular respiration? glycolysis alcoholic fermentation lactic acid fermentation the krebs cycle

Answer 1

I think the Krebs cycle is the correct answer since Glycolysis is wrong

Answer 2

Answer: The correct answer is Kreb cycle.

Cellular respiration is defined as the oxidation of food into CO₂ ( cabon dioxide) and H₂O ( water) in order to produce energy in the form of ATP ( adenosine triphosphate).

It occurs in three stages that is Glycolysis, Kreb cycle, and Electron transport chain.

Kreb cycle occurs in the matrix of the mitochondria. It includes the oxidation of a two carbon compound that is Acetyl- CoA in order to generate a pool of chemical energy in the form of ATP, NADH, FADH₂.

On the contrary, glycolysis and fermentation occur in the cytoplasm.

Thus, mitochondria is host to Kreb Cycle of the cellular respiration.
