Differentiate between anabolic and catabolic pathways. How are the pathways regulated ?

Answer»

S. No.	Anabolic pathways	Catabolic pathways
(i)	Anabolic pathway is called anabolism.	Catabolic pathways is known as catabolism
(ii)	It consumes energy to make complex molecules like glucose.	It liberates energy by breaking chemical bond. Glucose is broken down to release energy.
(iii)	Example: Photosynthesis.	Example: Cellular respiration.

Regulation of Pathways: (i) Biochemical pathways are tightly regulated by cells regulatory systems.

(ii) It depends on the allosteric site on the enzyme that catalyses the first reaction in the pathway.

(iii) The product of one reaction may serve as substrate for next reaction.

(iv) The method of regulating mechanism is feedback mechanism.
