How Does Aerobic Respiration Ultimately Depend On Photosynthesis?

Answer by Selmer T. on Mar 3 2014

Aerobic respiration depends on photosynthesis for two materials:
1. glucose which is the energy-bearing molecule made in photosynthesis and broken down in respiration
2. oxygen which is a waste product of breaking water molecules in photosynthesis and which is the final electron acceptor in respiration

Oxygen wouldn't do much good for respiration without some glucose to break down.

Photosynthesis and Aerobic Respiration Questions, Please help?

Photosynthesis: 1) What are all the reactions in photosynthesis? 2) How is oxygen changed/formed in each reaction? 3) How are the other molecules effected by oxygen? 4) How does it relates to the other process (aerobic respiration)? 5) How is water changed/formed in each reaction? 6) How are the molecules effected by water? 7) How does water related to the other process (aerobic respiration)? Aerobic respiration: same set of questions only with ATP and carbon dioxide now. basically, i have to right 4 stories, 2 for photosynthesis and 2 for aerobic respiration, from the view of the molecules that go through the reactions in each process and I need the informations. Thank you anyone who helped! All answers are appreciated but make sure they're accurate ;D

for photosynthesis i cant help you but as far as aerobic respiration goes to answer all of those questions you would need pages of information. I would look up Glycolosis and the krebs cycle in google you will find alot of the information you need.

Need help with Biology homework?

How does aerobic respiration ultimately depend on photosynthesis

because photosynthesis makes glucose (during calvin cycle)
we need glucose to respire aerobically.
glycolosis (break down of sugar) is the first step in A.R. and is used through out A.R. till the very end

Describe the processes of photosynthesis and aerobic respiration. Include how they are related.?

The processes of photosynthesis and cellular respiration are interdependent. That is, each process is necessary to fuel the other. So, the chemical products of photosynthesis are the chemical reactants of cellular respiration, and the products of cellular respiration are the reactants of photosynthesis.
Photosynthesis produces oxygen and glucose, which will be used in the set of reactions called cellular respiration. Photosynthesis consumes CO2 and gives off O2, while (aerobic) cellular respiration consumes O2 and gives off CO2, making these two a perfect complement, with the net effect being turning sunlight into the potential energy in the chemical bonds that comprise plants and animals.

Compare and Contrast: photosynthesis and cellular respiration.?

Please help at least suggestions cuz i need to study for a bio test to bring up my grade....10 easy points for u

1.Photosynthesis uses CO2 (produced in respiration)
2.Photosynthesis produces O2 (used in respiration)
3.Photosynthesis depends on light (respiration does not)
4.Photosynthesis needs chlorophyll (respiration does not)
5.Photosynthesis occurs in chloroplasts (respiration does not - uses mitochondria)
6.Photosynthesis uses NADP (respiration uses NADH)

True/False, WHY? Aerobic respiration occurs in animals but not plants, which make ATP only by photosynthesis?

True/False AND WHY? Aerobic respiration occurs in animals but not plants, which make ATP only by photosynthesis. is this true or false and why, please give as much detail as possible

This is absolutely false.

Many people think that because plants do photosynthesis, which turns carbon dioxide and water into simple sugars and oxygen, they must NOT do aerobic respiration, which is sort of the opposite process. This is absolutely not is a MYTH. Plant cells have mitochondria and therefore have the capacity to perform aerobic respiration.

When a plant performs photosynthesis, it is essentially capturing the energy in sunlight and storing it in the form of sugars. I'll restate this to emphasize its importance: the most important product of photosynthesis is sugar, NOT ATP. ATP is produced during part of photosynthesis, but it is used in a subsequent stage so there is not sufficient ATP production during photosynthesis to keep the plant alive.

So the plant stores sunlight energy in sugars during photosynthesis; what happens next? When the plant needs energy to carry out some of its metabolic processes, it must convert the stored energy in sugars into ATP. It does so through aerobic respiration, just like animal cells do. The big difference between energy metabolism in animals vs plants is that animals lack the ability to capture energy from sunlight; therefore, they must obtain it by eating other organisms.

I hope that helps. Good luck!
