The correct sequence of four carbon acids formed during Krebs cycle is
Options
- Aoxalo-acetic acid - fumaric acid - malic acid - succinic acid
- Boxalo-acetic acid - malic acid - fumaric acid - succinic acid
- Csuccinic acid - malic acid - fumaric acid - oxalo-acetic acid
- Dsuccinic acid - fumaric acid - malic acid - oxalo-acetic acid
Correct answer
D. succinic acid - fumaric acid - malic acid - oxalo-acetic acid
Step-by-step solution
During Krebs cycle, the first acid (from the given acids) to be formed is succinic acid as follows: Then fumaric acid is formed from succinic acid as follows: Then malic acid is formed from fumaric acid as follows: Then oxalo-acetic acid is formed from malic acid as follows:
