Question

Glycogenic amino acids enter TCA cycle except:

• A. $ \text{Alanine} $
• B. $ \text{Glycine} $
• C. $ \text{Glutamate} $
• D. $ \text{Aspartate} $

Hint:

Memorize amino acid catabolic fates — important for Biochemistry questions in GPAT.

Answer 1

The Correct Option is B

- Glycogenic amino acids are converted into intermediates of the TCA cycle, which ultimately lead to glucose formation via gluconeogenesis.
- Glycine is considered conditionally glucogenic, but it doesn't directly feed into a TCA intermediate without further conversion, making it an exception in this context.
