Question

If fat acts as respiratory substrates then they would need to be broken down into fatty acids and glycerol. If fatty acids were to be respired they would first be degraded to a______ and enter the pathway. Glycerol would enter the pathway after being converted to b______

• A. a—pyruvic acid, b—acetyl CoA
• B. a—acetyl CoA, b—PGAL
• C. a—PGAL, b—acetyl CoA
• D. a—acetyl CoA, b—pyruvic acid

Answer 1

Answer: (B)

If fat acts as respiratory substrates then they would need to be broken down into fatty acids and glycerol. If fatty acids were to be respired they would first be degraded to acetyl CoA and enter the pathway. Glycerol would enter the pathway after being converted to $PGAL$ /triose phosphate / $DHAP$
