C. Pyruvate dehydrogenase

D. Decarboxylation

1. $α$ - ketoglutaric acid

2. Hydrogen acceptor

3. Cytochrome-c

4. Acetyl Co - A

Codes

(a) Molecular oxygen ultimately combines with hydrogen to form water at the end of Electron Transport Chain (ETC).

Cytochrome-c is an electron acceptor in ETS.

Pyruvate dehydrogenase catalyses reaction converting pyruvic acid into acetyl Co- A.
