What is Mitochondria?

Mitochondria provide the energy a electric stall requirements to move, divide, induce secretory products, contract - in short, they ar the power centers of the cell. They are ab aside the size of bacteria but may moderate different shapes depending on the cell pillow slip. Mitochondria are membrane-bound organelles, and like the effect engender a double membrane. The discoverer membrane is slightly smooth. But the inner membrane is highly convoluted, forming folds called cristae. The cristae greatly growth the inner membranes surface area. It is on these cristae that food (sugar) is combined with type O to produce ATP - the primary energy showtime for the cell. Cells need energy for other processes such as the deduction of proteins from amino-acids and the coming back of DNA. This energy usually comes from the breakdown of glucose; though fats and proteins whoremaster in any case be employ a sources of energy. Glucose is a stable chemical: it does non pull out breakdown releasing energy. Since glucose can somerset through cell membranes it is used to canalise energy from virtuoso part of your consistency to another in your blood. Glucose cannot be stored by cells. They must qualify the glucose into glycogen. Both liver cells and muscle cells can store glycogen. Storing glucose is not possible for two reasons. Firstly it would just get out of the cell. Secondly it would postulate an enormous osmotic effect. Glycogen is not soluble so it cannot leak out of cells. Instead of storing tens of thousands of glucose molecules, the cell can store a fewer glycogen molecules which have rattling little osmotic effect.

ATP is very much(prenomina l) less stable than either glucose or glycog! en, so it cannot be used to store energy or to transport energy. Cells refer ATP when and where they need it. Muscle cells need a drove of ATP so... This is one of the best esays discussing mitochondria that I have perpetually read, and believe me, there is alot of them. Im interested in biology, so I started with a feeling that this wouldnt be that good, but as I read further and further it became better and better. I like it, how about you?
