NEET BIOLOGY

Detailed explanation-1: -Photosynthesis is a series of chemical reactions divided into two stages, the light reactions and the Calvin cycle. During the first stage, water is used and oxygen is produced. In the second and final stage, carbon dioxide is used, and glucose isproduced.

Detailed explanation-2: -It involves producing a three-carbon compound called 3-phosphoglyceric acid during the Calvin Cycle, which goes on to become glucose. C4 photosynthesis, on the other hand, produces a four-carbon intermediate compound, which splits into carbon dioxide and a three-carbon compound during the Calvin Cycle.

Detailed explanation-3: -Glucose and oxygen are the final products of photosynthesis.

Detailed explanation-4: -In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.
