Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which is exergonic?
A
catabolism
B
anabolism
Explanation: 

Detailed explanation-1: -Catabolic reactions give out energy. They are exergonic. In a catabolic reaction large molecules are broken down into smaller ones. For example, the reverse of the condensation reactions described above, i.e. hydrolysis reactions, are catabolic.

Detailed explanation-2: -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-3: -Examples of exergonic reactions include exothermic reactions, such as mixing sodium and chlorine to make table salt, combustion, and chemiluminescence (light is the energy that is released). If the temperature of the surroundings increases, the reaction is exothermic.

Detailed explanation-4: -The example of exergonic reactions occur in our body is cellular respiration: C6H12O6 (glucose) + 6 O2-> 6 CO2 + 6 H2O this reaction release energy which is used for cell activities. However, some exergonic reactions do not occur spontaneously and require a small input of energy to start the reaction.

Detailed explanation-5: -Catabolism occurs when you’re digesting food. For example, it’s the process that dissolves a piece of bread into simple nutrients your body can use, like glucose (blood sugar).
