Question

Which of the following steps of respiration is amphibolic?

• A. Glycolysis
• B. Oxidative decarboxylation of pyruvate
• C. TCA cycle
• D. Oxidative phosphorylation

Answer 1

The correct option is A Glycolysis

The term amphibolic is used to describe a biochemical pathway that involves both catabolism and anabolism. These are the most common ways smaller organic molecules can be formed into more complex ones and applies to the formation of carbs, proteins, lipids, and nucleic acids. Other type called reduction reaction, which involves the adding of hydrogens and electrons to a molecule. it gains calories of energy because energy is released when a hydrocarbon bond is split. Pathways of glycolysis are amphibolic pathways because they provide ATP and chemical intermediates to build new cell material. The fundamental metabolic pathways of biosynthesis are similar in all organisms, in the same way, that protein synthesis or DNA structure are similar in all organisms.

So the correct option is 'glycolysis'.
