HUMAN NUTRITION

Detailed explanation-1: -Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.

Detailed explanation-2: -This lesson focuses on one macromolecule, carbohydrates. They are composed of mono-and di-saccharides. Carbohydrates are the main source of energy for all living things. Glucose, (a monosaccharide) is produced by plants during photosynthesis and broken down by all living things to release the stored energy.

Detailed explanation-3: -Sunlight is converted to chemical energy in the form of ATP (adenosine triphosphate), which is the main energy-storing molecule in living organisms. ATP is then transported throughout the chloroplast and used to provide the chemical energy necessary to power other metabolic reactions.

Detailed explanation-4: -Photosynthesis takes place in two distinct stages. In the light reactions, energy from sunlight drives the synthesis of ATP and NADPH, coupled to the formation of O2 from H2O. In the dark reactions, so named because they do not require sunlight, the ATP and NADPH produced by the light reactions drive glucose synthesis.
