Q. Why is glucose said to provide instant energy to the body?
Ans. After we are exhausted we take the glucose solution to regain the energy. Actually, glucose is the smallest and simplest form of sugar that can be easily absorbed in blood, hence providing energy to the body. Whereas the carbohydrates, when consumed, have to be digested into glucose in order to produce energy. However, glucose when taken directly, need not to be digested. Hence it acts as an instant source of energy.
