Question

How many tricarboxylic acids are formed during in a single Krebs cycle: 1) Two 2) Three 3) Four 4) Six

Answer 1

Answer:

4

Step-by-step explanation:

• Citric acid
• Iso citric acid
• Cis-acotnic acis
• Oxalo succinic acid

Answer 2

The total number of tricarboxylic acids formed during a single Kreb cycle is B. Three

Tricarboxylic acids formed are -

1. Citric acid
2. Isocitric acid
3. Oxalosuccinic acid

The formation process of tricarboxylic acids -

• Citric acid is formed by the reaction of acetyl coenzyme A with oxaloacetic acid.
• Citric acid forms isocitric acid by reorganizing itself.
• Oxalosuccinic acid is formed by the dehydrogenation of isocitric acid.

Kreb cycle consists of 8 cyclic step processes.
