Glycolysis operates as long as it is supplied with NAD that can pick up hydrogen atoms.

Enzymes of TCA cycle are present in mitochondrial matrix.

Oxidative phosphorylation takes place in outer mitochondrial membrane.

Glycolysis occurs in cytosol.

It is the final electron acceptor for anaerobic respiration.

It functions as an enzyme.

It functions as an electron carrier.

It is a nucleotide source for ATP synthesis.

There is one point in the cycle where FAD⁺ is reduced to FADH₂.

During conversion of succinyl CoA to succinic acid, a molecule of GTP is synthesised.

The cyclic starts with condensation of acetyl group (acetyl CoA) with pyruvic acid to yield citric acid.

There are three points in the cycle where NAD⁺ is reduced to NADH + H⁺.

formation of ATP by transfer of phosphate group from a substrate to ADP

oxidation of phosphate group in ATP

addition of phosphate group to ATP

formation of ATP by energy released from electrons removed during substrate oxidation.
