Question

Which of the following is an example of Anabolic pathway?

• A. Glucose becomes lactic acid
• B. Acetic acid becomes cholesterol
• C. Cellular respiration
• D. All of these

Answer 1

The correct option is B

Acetic acid becomes cholesterol

Metabolic pathways can lead to a more complex structure from a simpler structure (for example, acetic acid becomes cholesterol) or lead to a simpler structure from a complex structure (for example, glucose becomes lactic acid in our skeletal muscle). The former cases are called biosynthetic pathways or anabolic pathways. The latter constitute degradation and hence are called catabolic pathways. Cellular respiration is also a catabolic pathway as the 6 carbon compound, glucose breaks down to give two 3 carbon compounds-pyruvic acid with the release of energy in the form of ATP.
