Aerobic respiration traps energy using oxygen as the ultimate electron receptor - see details for photosynthesis. Aerobic respirationAerobic respiration requires oxygen in order to generate energy (ATP). It is the preferred method of pyruvate breakdown from glycolysis and requires that pyruvate enter the mitochondrion to be fully oxidized by the Krebs cycle.

The product of this process is energy in the form of ATP (Adenosine Triphosphate), by substrate-level phosphorylation, NADH and FADH2. Simplified Reaction: C6H12O6 (aq) + 6O2 (g)? 6CO2 (g) + 6H2O (l)?

Hc -2880 kJThe reducing potential of NADH and FADH2 is converted to more ATP through an electron transport chain with oxygen as the "terminal electron acceptor". Most of the ATP produced by aerobic cellular respiration is made by oxidative phosphorylation. This works by the energy released in the consumption of pyruvate being used to create a chemiosmotic potential by pumping protons across a membrane.

This potential is then used to drive ATP synthase and produce ATP from ADP. Biology textbooks often state that between 36-38 ATP molecules can be made per oxidised glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 32-34 from the electron transport system). Generally, 38 ATP molecules are formed from aerobic respiration.

However, this maximum yield is never quite reached due to losses (leaky membranes) as well as the cost of moving pyruvate and ADP into the mitochondrial matrix. Aerobic metabolism is 19 times more efficient than anaerobic metabolism (which yields 2 mol ATP per 1 mol glucose). They share the initial pathway of glycolysis but aerobic metabolism continues with the Krebs cycle and oxidative phosphorylation.

The post glycolytic reactions take place in the mitochondria in eukaryotic cells, and in the cytoplasm in prokaryotic cells. Photosynthesis: See link below for more details. http://en.wikipedia.org/wiki/PhotosynthesisPhotosynthesis is the conversion of light energy into chemical energy by living organisms.

The raw materials are carbon dioxide and water, the energy source is sunlight, and the end-products include glucose and oxygen. It is arguably the most important biochemical pathway,1 since nearly all life depends on it. It is a complex process occurring in higher plants, phytoplankton, algae, as well as bacteria such as cyanobacteria.

Photosynthetic organisms are also referred to as photoautotrophs.1The word comes from the Greek photo-, light, and synthesis, putting together. Sources: http://en.wikipedia.org/wiki/Aerobic_respiration .

Mitochondria in the cells of people use oxygen to burn fuel(fat, glucose etc), Photosynthesis- Chloroplasts.... act like the mitochondria in people and make energy from sunlight and they make sugar and oxygen. We use sugar and oxygen and make ATP energy from it in our mitochondria.

Do it yourself. You arent going to learn squat if you have everyone else do your work for you...

3 first time post from me on here, and quite frankly I hate biology, and im studying the answers for a final, so enough with the attitude.

Diagram of the relationship of photosynthesis and aerobic respiration.

How many can I get from using the word respiration.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
