Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
____ is the exergonic breakdown of substrates
A
metabolism
B
anabolism
C
catabolism
D
exernism
Explanation: 

Detailed explanation-1: -Exergonic reactions in organisms are called catabolic reactions. These reactions break down molecules into smaller units and release energy. An example of a catabolic reaction is the breakdown of glucose during cellular respiration, which releases energy that cells need to carry out life processes.

Detailed explanation-2: -Exergonic reactions are chemical reactions that release energy in the form of heat. Typically, this energy is released when bonds are broken. More specifically, in humans, these reactions are called catabolic, which means that the molecules are being broken down into smaller components.

Detailed explanation-3: -That means that a reaction can either release energy useful for work (an exergonic reaction) or requires energy to proceed (an endergonic reaction). The production of ATP during catabolism is therefore exergonic, whereas anabolism is an endergonic reaction.

Detailed explanation-4: -Anabolic reactions are endergonic reactions, meaning that they require an input of energy. Catabolism is the process of breaking down complex molecules into simpler molecules.
