Question

Carbohydrates are most suitable for the production of energy in the body than proteins and fats.
Reason: Carbohydrates can be stored in the tissues as glycogen and can be used for production of energy whenever necessary.
a) Both assertion and reason are correct and reason is the correct explanation for assertion.
b) Both assertion and reason are correct but reason is not the correct explanation for assertion.
c)Assertion is correct but reason is incorrect.
d)Both assertion and reason are incorrect.

Answer 1

Hint: Carbohydrates are the main source of energy production in the human body. The carbohydrates present in the diet taken by us is converted into glucose before it enters the bloodstream. The glucose is taken in by blood and is then used for the formation of an energy molecule of ATP which is required by the body to work.

Complete answer: Carbohydrates are the major source of energy production in our body. They are also more suitable for the energy production as compared to the proteins and fats. This is so because the carbohydrates have the presence of more oxygen molecules than the fats and proteins. So, it doesn’t require oxygen for the process of oxidation. The diet consumed by a person contains carbohydrates in major amounts. This carbohydrate is then used for all the metabolic functions and is also used for all the anaerobic exercises done by the body. The carbohydrates present in the diet taken by us is converted into glucose before it enters the bloodstream. The glucose is taken in by blood and is then used for the formation of an energy molecule of ATP which is required by the body to work. The excess of glucose formed is converted into glycogen. This glycogen is stored in the muscles or in the liver. Whenever there is a requirement for glucose, the stored glycogen can be used easily.

So, the answer is ‘Both assertion and reason are correct and the reason is the correct explanation for assertion’.

Note: The carbohydrates are converted to glucose before it enters the bloodstream from the intestine. The glucose is taken in by blood and is then used for the formation of energy molecules which is required by the body to work.
