Second stage of cellular respiration is
The stage happens in mitochondria.
Oxygen combines with small molecules.
Energy is released.
<u>Explanation:</u>
Krebs cycle is the another name for second stage of cellular respiration . Throughout this stage, pair of molecules of ATP are generated. Another energy-storing molecules are also produced. Into the mitochondrial matrix which is the deepest part of mitochondria, all pyruvate from glycolysis (from first stage) moves.
The Krebs cycle lacks oxygen. Anything that requires oxygen is represented as aerobic. The oxygen blends with the carbon from the pyruvate molecules. This creates carbon dioxide, a waste product. As a result of second stage NADH is generated.
