Question

Which of the following are correct with reference to amino acids?

• A. Proteins are made up of 19 different amino acids
• B. They become part of the respiratory pathway only as acetyl CoA
• C. Amino acids are degraded to proteins by enzyme protease
• D. None of the above

Answer 1

The correct option is D None of the above

A chain/polymer of amino acids make proteins. Amino acids play a critical role in our body such as synthesis of hormones. Our body needs 20 different amino acids to grow and function properly. Proteins are generally made up of 20 different amino acids. Proteins are degraded to amino acids by proteases. Depending on their structure, amino acids would enter the pathway at some stage within the Krebs cycle or even as pyruvate or acetyl CoA.
