DENDROLOGY

Detailed explanation-1: -Catabolism is the break down of complex molecules. Catabolism is the breakdown of complex substances to their constituent parts (glucose, amino acids and fatty acids) which form substrates for metabolic pathways. Metabolism comprises two major parts; one is anabolism and the other catabolism.

Detailed explanation-2: -Catabolic reactions break down larger molecules, such as carbohydrates, lipids, and proteins from ingested food, into their constituent smaller parts. They also include the breakdown of ATP, which releases the energy needed for metabolic processes in all cells throughout the body.
