Question

what do we get instant energy from gloucose

Answer 1

glucose is a simple sugar. Glucose can easily dissolve in our blood and hence when glucose is taken it does not need to be digested and thus gets absorbed quickly.

Answer 2

Glucose is a simple sugar. Carbohydrates, when consumed, have to be digested into glucose. As glucose can be easily absorbed in blood, it provides energy to the body. Hence, when glucose is directly taken, it does not have to be digested and thus acts as an instant source of energy
