⚡️Link Reaction

What happens to pyruvate in the link reaction?

Pyruvate is converted into acetyl coenzyme A.

What molecule is lost from pyruvate during its conversion to acetyl coenzyme A? and What is this process called

A carbon is lost in the form of carbon dioxide (CO2).This process is called Oxidative decarboxylation.

What is the process called when carbon dioxide is removed from pyruvate?

Decarboxylation.

What molecule does NAD become when it steals hydrogen from pyruvate?

NADH.

What type of reaction occurs during the link reaction due to the loss of hydrogen from pyruvate?

Oxidative decarboxylation.

What is formed from pyruvate after oxidative decarboxylation, that then joins with coenzyme A to create acetylcoenzyme A?

An acyl group.

What is the role of coenzyme A in the link reaction?

To temporarily stabilize the acyl group before it enters the Krebs cycle.

How many carbons does acetyl coenzyme A contain?

Two carbons.

What is the structure of pyruvate?

A three-carbon molecule.

What is the purpose of the link reaction in cellular respiration?

To convert pyruvate into acetyl coenzyme A for entry into the Krebs cycle.
