Question

A source of maximum energy is
A.Carbohydrate
B.Fat
C.Protein
D.Vitamins

Answer 1

Hint:The energy got from any supplement is through its oxidation. Maximum energy can be derived from fat molecules as compared to any other biomolecule. The energy derived from any nutrient is through its oxidation.

Complete answer:
Greatest energy can be gotten from fat particles when contrasted with some other biomolecules. Fatty acids are in most diminished structures due to the presence of H, consequently oxidizing such vigorously decreased particles yields more energy. The significant type of fat in people is triglyceride or triacylglycerol TAG which is an ester of glycerol and three fatty acids. For instance, one particle of palmitate, a 16-carbon saturated fatty acid, would yield 106 ATP after complete oxidation. Though, oxidation of one atom of glucose yields a limit of 30 ATP after glycolysis, TCA cycle and electron transport chain. Likewise, proteins are separated to amino acids which can be utilized for making new proteins or can be additionally separated to α-keto acids to be utilized in metabolic pathways yielding energy far not as much as what is created by fatty acid oxidation.
Despite the fact that fats are the most energy-thick of the three energy-yielding supplements, sugars, which give four Calories/gram are your body's best option for energy, particularly immediate energy.
So, the correct answer is option B.

Note:- In metabolic cycle the most extreme energy is given by fats
- For a functioning grown-up around 2000-2500 cal/day energy is required.
- 1 gm of carbohydrate gives approx. 4 cal energy.
- 1 gm of protein gives approx. 4 cal energy.
- 1 gm of fats gives aproxx9 cal energy.
