What are the starting materials and products of photosynthesis and cellular respiration?

Answer 1

1. Photosynthesis consumes carbon dioxide and water to create oxygen and organic molecules. Tt is endergonic, H2O is oxidized and the CO2 is reduced, ETC is in the thylakoid membrane in the chloroplast, protons move from thylakoid space into stroma, and ATP is synthesized into glucose.
2. Cellular respiration consumes oxygen and organic molecules to create carbon dioxide and water. It is exergonic, glucose is oxidized and O2 is reduced, ETC is in the cristae (inner membrane) in mitochondria, protons move from the inner membrane space into the matrix, and glucose if catabolized to synthesize ATP.

Answer 2

simply put cellular respiration: raw material: glucose + oxygen by product: co2 product: atp photosynthesis: raw materail: co2 + water by product: o2 (oxygen) product: atp man i hope that helped with your 4th grade science homework

Answer 3

1. Photosynthesis occurs only in the presence of light, where light energy drives the formation of ATP and NADPH, and the oxygen is released. Respiration occurs at all times in cells.

2. God made mammal life to where it is co-dependent upon plant life, and vice versa.

3. Photosynthesis and respiration formulas are mirror images, making them equal, but opposite.

Answer 4

The processes are essentially opposite reactions. Photosynthesis forms carbohydrates (glucose, sugar) from carbon dioxide and water, releasing oxygen in the process. Cellular respiration uses the stored energy by oxidizing the carbohydrates and releasing water and carbon dioxide.

Photosynthesis: 6(CO2) + 6(H2O) + Light Energy ---> C6H12O6 + 6(O2)

Cellular respiration (simple): C6H12O6 + 6(O2) ---> 6(CO2) + 6(H2O) + energy

Answer 5

In photosynthesis, the starting materials are carbon dioxide and water, which are converted by plants into glucose and oxygen. In cellular respiration, the starting materials are glucose and oxygen, which are broken down by cells to produce carbon dioxide, water, and energy in the form of ATP.
