Mitochondrion is an organelle that is found in cells that creates the energy so that cells can use them to survive and maintain stability of cellular activity. Most people confuse mitochondria with mitochondrion because mitochondrion is a single thing while mitochondria are multiple mitochondrion. You just have to understand that because it would not be good if you confuse them. Furthermore, it is a very essential organelle in the cell because of its uses.
Main ideas :
- Found ONLY in eukaryotic cells.
- Creates ATP using aerobic or anaerobic respiration. (Cellular Respiration)
- The amounts of mitochondria in a cell depend on its use of energy need.
- They have folds on their surface (called cristae) that increase the efficiency of ATP produced.
- One of the few organelles that have double membranes. (Inner membrane and outer membrane)
- Contain their own DNA (called Mitochondrial DNA)
- Also contain ribosomes.
Summary : Mitochondrion is a vital organelle (little organ) because everybody considers it like a NEED for life. They create energy by breaking the bonds between phosphates and release energy for the cell's use. It starts when plants release oxygen and glucose and mitochondria grasp the products of the photosynthesis where they become the reactants of cellular respiration and the plants store the energy in chemical bonds and mitochondria breaks the bonds and when it breaks it, the energy is just given away to the cell. It is also regularly confused that mitochondria releases energy by storing it in bonds. But, that does not make the slightest sense of all. The actual thing is that it releases energy by BREAKING the bonds of glucose where the energy is stored. Another common misconception is that people think plants don't have mitochondria because they think plants don't have muscles and so on. But, plant cells DO have mitochondria and that is just like the way we have mitochondria (You can also see mitochondria of plant cells in the image above). In conclusion, Mitochondria are very crucial organelles that require for a cell's growth, activity and functioning.
