LIFE SCIENCE

Detailed explanation-1: -The reaction C 6 H 12 O 6 ( aq ) + 6 O 2 ( g ) → 6 CO 2 ( g ) + 6 H 2 O ( l ) + ∆ Glucose Oxygen carbon water heat dioxide is exothermic.

Detailed explanation-2: -Oxygen (O2) is evolved during photosynthetic electron transport when water is split by the oxygen-evolving complex to provide protons and electrons to the chloroplastic electron chain, thereby generating ATP and NADPH-the energy source and reducing power for plant metabolism.

Detailed explanation-3: -Most life on Earth depends on photosynthesis. The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O2) and chemical energy stored in glucose (a sugar).
