Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which organic molecule is primarily used by cells as a source of energy?
A
Amino Acid
B
Fatty Acid
C
Glucose
D
Protein
Explanation: 

Detailed explanation-1: -Adenosine 5’-triphosphate, or ATP, is the most abundant energy carrier molecule in cells. This molecule is made of a nitrogen base (adenine), a ribose sugar, and three phosphate groups.

Detailed explanation-2: -Different Cell Types Require Different Fuel Molecules. Red blood cells rely on glucose for energy and convert glucose to lactate. The brain uses glucose and ketone bodies for energy. Adipose tissue uses fatty acids and glucose for energy.

Detailed explanation-3: -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-4: -A molecule of glucose, which has the chemical formula C6H12O6, carries a packet of chemical energy just the right size for transport and uptake by cells. In your body, glucose is the “deliverable” form of energy, carried in your blood through capillaries to each of your 100 trillion cells.
