Assertion (A): More energy is released (38 ATP) in the aerobic respiration as compared to anaerobic respiration during which only 2ATPs are produced by the breakdown of one molecule of glucose.
Reason (R): Complete oxidation of glucose occurs in presence of oxygen whereas glucose cannot be broken down completely in absence of oxygen. Hence, amount of energy produced varies between the two kinds of respiration.
- Both A and R are true and R is the correct explanation of A.
- Both A and R are true but R is not the correct explanation of A.
- A is true but R is false.
- A is false but R is true.
Assertion (A): Photosynthesis occurs in the cells of leaves which contain chloroplasts whereas respiration occurs in all other cells which lack chloroplasts.
Reason (R): The pigment chlorophyll traps solar energy for the process of photosynthesis whereas it does not participate in the process of respiration.

- Both A and R are true but R is not the correct explanation of A.
