MCQ
Aerobic respiratory pathway is appropriately termed:
- ACatabolic
- BParabolic
- CAmphibolic
- DAnabolic
Explanation:
A metabolic pathway that participates in both anabolic and catabolic pathways is called amphibolic.
The citric acid cycle (Krebs cycle) is a good example of the amphibolic pathway.
The first reaction of the cycle, in which oxaloacetate (a four-carbon compound) condenses with acetate (a two-carbon compound) to form citrate (a six-carbon compound) is typically anabolic.
The next few reactions are typically catabolic.
