4/Name the pathway that will provide reducing equivalents for fatty acid synthesis [1 mark]

short answer

Answer 1

Question

1. Chenodeoxycholate is the most powerful detergent among all the substance given. Hence, option D is correct.

2. Drug methotrexate inhibits the function of enzyme known as dihydrofolate reductase that catalyzes folic acid to tetrahydrofolic acid. Hence, option D is correct.

3. As erythrocytes are devoid of mitochondria they only use glucose to derive energy. Hence, option E is correct.

4. The Krebs cycle is the source of producing equivalent for fatty acid synthesis.
