The second organelle that I would like to discuss is the mitochondria. The mitochondrion isn’t a very big organelle but they are very important because multiple processes occur inside them. The first process that I would like to discuss that takes place in the mitochondria is cellular respiration. Cellular respiration is such an important biochemical process to us human beings, it’s because it is how we derive energy from what we eat, and the glucose we get from it. Also cellular respiration takes place at the cellular level. It takes our food we intake and breaks it down in the presence of oxygen to make ATP, that energy form that we want. We have aerobic respiration, which is cell respiration that occurs in the presence of oxygen, for example …show more content…
For example this is when you take off in a dead sprint and your body is unable to run this process fast enough to keep up with you. Respiration is for heterotroph which is what we are, and we take organic compounds in the presence of oxygen and converting then into carbon dioxide and water and we also generate ATP here. We take glucose into the presence of oxygen which gives up carbon dioxide and water and a little bit of ATP. The energy comes from the hydrogen when oxygen pulls the hydrogen towards it. In the mitochondria we have the cristae which are the folds on the inside. We also have two membranes an inner one as well as an outer one. They are able to reproduce through binary fission. Now there are three steps in cellular respiration that are all very important. The first step is what we call glycolysis, the krebs cycle and the electron transport chain. So first in glycolysis takes place outside of the mitochondria where we take the glucose and break it down into pyruvate. Here we get some ATP and some NADH. Pyruvate then migrates into the mitochondria, and forms acetyl-coA which will then enter into the Krebs
