Assertion (A): Respiration is an exothermic process.
Reason(R): The glucose combines with oxygen in the cells of
our body and provides energy.
a) Both A and R are true, and R is the correct explanation of the assertion.
b) Both A and R are true, but R is not the correct explanation of the assertion.
c) A is true, but R is false.
d) A is false, but R is true.
Option A is correct.
During respiration, glucose combines with oxygen in the cells of our body to form carbon dioxide and water along with the production of energy. The balanced equation can be shown as:
C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy
Respiration is termed as exothermic process since energy is released during this process.
Hope it helps.
