Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which refers to the breakdown of macromolecules into simpler building blocks?
A
metabolism
B
catabolism
C
anabolism
D
condensation
Explanation: 

Detailed explanation-1: -Catabolism is referred to as a series of metabolic pathways that are involved in the conversion of macromolecules into simpler molecules or monomers.

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.

Detailed explanation-3: -When polymers are broken down into smaller units (monomers), a molecule of water is used for each bond broken by these reactions; such reactions are known as hydrolysis reactions. Dehydration and hydrolysis reactions are similar for all macromolecules, but each monomer and polymer reaction is specific to its class.

Detailed explanation-4: -Anabolism is the process where smaller or simpler molecules combine to form larger and more complex substrates. Catabolism is where larger and more complex molecules are broken down into smaller and simpler molecules.

Detailed explanation-5: -Catabolism is the set of metabolic processes that break down large molecules. These include breaking down and oxidizing food molecules. The purpose of catabolic reactions is to provide the energy and components needed by anabolic reactions.
