Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Where does the energy for making ATP usually come from?
A
nucleic acids
B
proteins
C
lipids
D
carbohydrates
Explanation: 

Detailed explanation-1: -In general, the main energy source for cellular metabolism is glucose, which is catabolized in the three subsequent processes-glycolysis, tricarboxylic acid cycle (TCA or Krebs cycle), and finally oxidative phosphorylation-to produce ATP.

Detailed explanation-2: -One of the primary functions of carbohydrates is to provide your body with energy. Your cells convert carbohydrates into the fuel molecule ATP through a process called cellular respiration.

Detailed explanation-3: -It is the creation of ATP from ADP using energy from sunlight, and occurs during photosynthesis. ATP is also formed from the process of cellular respiration in the mitochondria of a cell. This can be through aerobic respiration, which requires oxygen, or anaerobic respiration, which does not.

Detailed explanation-4: -When you eat carbs, your body breaks them down into simple sugars, which are absorbed into the bloodstream. As the sugar level rises in your body, the pancreas releases a hormone called insulin. Insulin is needed to move sugar from the blood into the cells, where the sugar can be used as a source of energy.

Detailed explanation-5: -Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP .
