Question

Fatty acids enter cellular respiration as

• A. one-carbon fragments
• B. two-carbon fragments
• C. three-carbon fragments
• D. long chain-carbon fragments

Answer 1

Answer: (B)

two-carbon fragments

Cellular respiration is the process in which sugar is broken down to obtain energy. The first step of fatty acid in cellular respiration is the entering of acetyl CoA in the Krebs cycle which is after the process of glycolysis. Acetyl CoA is a fatty acid which is two carbon compounds product which gets condensed by an enzyme and forms the first product of Krebs cycle which is six carbon compound.

So, the correct option is ' two-carbon fragments'.
