What happens during the light-dependent and light-independent reactions of photosynthesis?

What roles do water, light, carbon dioxide, and chlorophyll play in photosynthesis?

How does glycolysis contribute toward aerobic respiration, anaerobic respiration and fermentation?

How do temperature, water, and oxygen affect respiration?

Answer 1

1. Light dependent reactions uses energy from sunlight to produce oxygen with the help of ADP and NADH to convert them to energy producing molecules like ATP and NADPH. whereas the light independent reactions utilizes the ATP and NADPH produced in light dependent reactions to further form high sugar compounds.

2. The green plants uses the sunlight energy to convert the water which splits to release electrons for the electron transport chain and carbondioxide into carbohydrates such as glucose . This process is called as photosynthesis. The light from sun as in form of energy is absorbed by the green coloured pigment present in the leaves of the green plants which is known as chlorophyll and the carbon dioxide and oxygen from the air transports via stomata of the leaf.

3. The glycolysis produces the pyruvic acid which further in aerobic respiration converts to the acetyl Co-A to enter to the kreb cycle, in anaerobic respiration it leads to the formation of lactic acid whereas in fermentaion it leads to the formation of ethanol.

4. The rate of respiration is increased as the temperature, water and oxygen increases because of the direct proportionality relation .
