Cellular Respiration

This week in AP Biology we talked about cellular respiration. Cellular respiration is the metabolic process whereby certain organisms obtain energy from organic molecules. Without cellular respiration, no organism would be able to acquire energy. Another thing we discussed in class was aerobic and anaerobic respiration. Aerobic uses oxygen while anaerobic does not use oxygen. Also anaerobic produces lactic acid while aerobic does not. Lactic acid is produced in the muscle tissues during an intense exercise. That is why when someone gets done with a difficult workout they pant for oxygen because your body is getting all of the lactic acid out and taking oxygen in. There are three steps in cellular respiration, and they are glycolisis, Kreb's cycle, and Electron Transport Chain (ETC). Each one of these steps build up on each other to make several ATP's. (I don't know the cycle very well enough as of now to explain it very thoroughly). Cellular respiration is very important to any organism because we need energy to make our body work properly.
