Question

what are the similarities between cellular respiration and photosynthesis ?

Answer 1

Respiration is the process by which energy is released. Photosynthesis captures energy. They are complementary. They both involve energy changes and Oxygen is a reactant. Respiration is very simply, C6H12O6+O2-> 6CO2+6H2O+Energy released and Photosynthesis is the reverse reaction. Only green plants can perform photosynthesis.

Answer 2

Every living being has to respire. I meant Oxygen is a reactant in respiration.

Answer 3

5- Similarities
1) Both involve electron transport chains.
2) Chemiomosis allows ATP synthase to produce ATP.
3) Both take place at some point within an organelle (mit. = CR, chloroplast= photo.)
4) Both utilize ATP for energy at some points.
5) Both provide power for cellular activities.
5- Differences
1)Cellular respiration depends on oxygen as a substrate.
2)Photosynthesis utilizes 2 electron transport chains (not just 1).
3)In Photo. , energy is provided by photons and not catatonic processes as in cell. resp.
4)Photosynthesis involves the production of NADPH (CR involves NADH and FADH2)
5)Photosynthesis involves CO2 and H20 as substrates (splitting h20 provides the electrons for the process).

Answer 4

Ay Yo,that is a phenomenal answer. Don't worry about those pesky centigrams now, your totally rock this.
