Question

What are the main steps in aerobic respiration where does it takes place?

Answer 1

Main steps:
(1) Glycolysis = occurs in cytoplasm of cell
(2) The link reaction - occurs in mitochondrial matrix
(3) The Krebs Cycle - occurs in mitochondrial matrix
(4) Oxidative phosphorylation - occurs in mitochondrial membrane

Answer 2

Answer:

Main steps in aerobic respiration are as follows

• Glycolysis: Occurs in the cytoplasm(cytosol) where glucose is broken down to pyruvic acid.

• Oxidative decarboxylation of pyruvic acid to acetyl coenzyme-A: Takes place inside the mitochondrial matrix.

• TCA or Krebs cycle takes place in Mitochondrial matrix where pyruvic acid is oxidized to transform the energy contained in these molecules into ATP.

• Electron transport chain occurs in mitochondrial membrane involves ATP synthase complex.
