Complete this sentence. Metabolism is ____
A
the sum of all reactions that take place in the body.
B
covers some of the reactions that take place in the body.
C
the total amount of energy used subtracted from the total amount consumed.
Explanation: 

Detailed explanation-1: -Metabolism is the sum total of all chemical reactions occuring in our body. It is made up of catabolism and anabolism.

Detailed explanation-2: -Metabolism refers to the whole sum of reactions that occur throughout the body within each cell and that provide the body with energy. This energy gets used for vital processes and the synthesis of new organic material.

Detailed explanation-3: -Chemical reactions that take place inside living things are called biochemical reactions. The sum of all the biochemical reactions in an organism is referred to as metabolism. Metabolism includes both exothermic (heat-releasing) chemical reactions and endothermic (heat-absorbing) chemical reactions.

Detailed explanation-4: -Metabolism is the sum of every chemical reaction that happens inside the body. Scientists understand metabolism as the sum of the processes of breaking down, known as catabolism, and of building up, or anabolism, that sustains life.

Detailed explanation-5: -Where do metabolic reactions happen? Metabolic reactions happen in specific locations in the cell. Glycolysis, fatty acid synthesis, and glycogen synthesis happen in the cytoplasm, along with some steps of amino acid breakdown. Several metabolic pathways are in specific locations inside of mitochondria.
