Photosynthesis And Cellular Respiration - Photosynthesis
Aerobic respiration and anaerobic respiration are metabolic processes. They both release energy that is then used by other metabolic processes, eg. protein synthesis. Anaerobic respiration can only take place for a short period of time because it produces toxic waste, ie. lactic acid and this poisons muscle: it gives you cramp.
Aerobic respiration takes place in almost all living things. It is easy to get rid of the Carbon Dioxide and excess water; this is excretion (the removal of the toxic waste products of metabolism), and maximum energy is released from the glucose.
Activities, games, puzzles, labs, and links for the study of life.
Anaerobic respiration (both glycolysis and fermentation) takes place in the fluid portion of the cytoplasm whereas the bulk of the energy yield of aerobic respiration takes place in the . Anaerobic respiration leaves a lot of energy in the ethanol or lactate molecules that the cell cannot use and must excrete.
Glycolysis itself yields two ATP molecules, so it is the first step of anaerobic respiration. , the product of glycolysis, can be used in to produce ethanol and + or for the production of lactate and NAD+. The production of NAD+ is crucial because glycolysis requires it and would cease when its supply was exhausted, resulting in cell death. A general sketch of the anaerobic steps is shown below. It follows Karp's organization.

Aerobic respiration, or in the presence of oxygen, uses the end product of (pyruvate) in the to produce much more energy currency in the form of than can be obtained from any . Aerobic respiration is characteristic of when they have sufficient oxygen and most of it takes place in the .
Some organisms can respire in the absence of air: this is anaerobic respiration. This does not release so much energy and it produces much more toxic waste products. However, if Oxygen is not available, anaerobic respiration is better than nothing. When this happens in our muscles we produce lactic acid which gives you cramp. The bacteria in milk produce the same chemical when they turn it sour. “Lactic” means “of milk”. So lactic acid is the acid in sour milk. Yeasts produce alcohol which is also toxic. Eventually there will be so much alcohol that the yeast cannot survive.

As you can see anaerobic respiration is not as efficient as aerobic and only a small amount of energy is released
