Mitochondrion is an organelle found both in plant and animal cells which provides energy to the cell by cellular respiration. The structure of mitochondrion, cellular respiration and the endosymbiotic theory will be discussed in this essay. In comparison with some of the other organelles within the cell, mitochondria serve some unique purposes in the function of the cell.
Structure
As known, all organelles have different important structures. Mitochondrion consists of an outer membrane, inner membrane, cristae and a matrix. Each of these serve a special job and without these, mitochondrion couldn’t make the energy that the cell needs.
Mitochondrion and chloroplast are the only organelles that are surrounded by two membranes. These two organelles complete each other in other ways too – chloroplasts use carbon dioxide and food to produce oxygen and sugar by photosynthesis and mitochondria use oxygen and sugar to produce carbon dioxide, water and energy by cellular respiration.
The outer membrane is like the customs of the mitochondrion. It allows the substances in and out of the organelle. It also protects the cell. The inner membrane is the place where many chemical reactions occur. Between the inner and outer membranes, …show more content…
There are two forms of cellular respiration that are called aerobic and anaerobic respiration. Aerobic respiration requires oxygen and anaerobic doesn’t, but they both use glucose to make ATP. ATP stands for adenosine triphosphate. Aerobic respiration occurs slowly but makes a lot of ATP compared to anaerobic respiration, which occurs faster but makes only a little amount of ATP. Prokaryotic cells don’t have mitochondria, so anaerobic respiration occurs in the cytoplasm of the cell and it will not be discussed further in this essay. In eukaryotic cells the aerobic respiration occurs in the cytoplasm and in the
