What is the site of Krebs cycle in mitochondria?

The Krebs cycle, also known as the citric acid cycle or tricarboxylic acid (TCA) cycle, occurs in the mitochondrial matrix.

The mitochondrial matrix contains all the necessary enzymes for the Krebs cycle, except for succinate dehydrogenase, which is located in the inner mitochondrial membrane.

The outer membrane is involved in the transport of molecules.

Oxysomes (F0-F1 particles) are present on the inner mitochondrial membrane and are involved in ATP synthesis.

Cristae are the infoldings of the inner mitochondrial membrane that house the electron transport chain.

Answer: Matrix
