• 2

• 3

• 4

The products of the link reaction are

• pyruvate and carbon dioxide

• carbon dioxide and co-enzyme A

• carbon dioxide, acetyl coA and NADH

• NADH and carbon dioxide

The removal of carbon from a molecule in the form of carbon dioxide is known as

• decarboxylation

• dehydrogenation

• phosphorylation

• oxidation
