OBJECTIVE FORESTRY

Detailed explanation-1: -In this reaction, the energy from ATP and NADPH are used to fix carbon dioxide (CO2). So NADH is not a product of the light reaction of photosynthesis.

Detailed explanation-2: -When NAD oxidises a molecule by accepting electrons and adding hydrogen ions to the chemical, it produces NADH. The initial phase of photosynthesis is the light reaction, which converts solar energy into chemical energy. Solar energy is absorbed by chlorophyll during this process, and water is photolyzed.

Detailed explanation-3: -The light reaction of photosynthesis, also called the light-dependent stage, occurs at the beginning of photosynthesis and uses light energy, water, ADP, and NADP+ to produce oxygen, ATP, and NADPH.
