Which is the primary molecule in the cell that is broken down to get energy?
A
Salt
B
Sugar
C
Water
D
Protein
Explanation: 

Detailed explanation-1: -Glucose and other food molecules are broken down by controlled stepwise oxidation to provide chemical energy in the form of ATP and NADH.

Detailed explanation-2: -adenosine triphosphate (ATP), energy-carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.

Detailed explanation-3: -In the cell cytoplasm, glucose is broken down to pyruvate. On entry to the mitochondria, pyruvate is converted to carbon dioxide and water. Its chemical potential energy is transferred to ATP.
