What is Mitochondria?

Mitochondria provide the energy a electric kiosk 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 admit different shapes depending on the cell example. Mitochondria are membrane-bound organelles, and like the focalise engender a double membrane. The surfaceer membrane is moderately smooth. But the inner membrane is highly convoluted, forming folds called cristae. The cristae greatly addition the inner membranes surface area. It is on these cristae that food (sugar) is combined with type O to produce ATP - the primary energy stock for the cell. Cells need energy for other processes such as the subtraction 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 utilize a sources of energy. Glucose is a stable chemical: it does non eject b reakdown releasing energy. Since glucose can somerset through cell membranes it is used to canalise energy from virtuoso part of your remains to a nonher in your blood. Glucose cannot be stored by cells. They must substitute 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 concur 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 such(prenominal)! less stable than either glucose or glycogen, so it cannot be used to store energy or to transport energy. Cells accomplish ATP when and where they need it. Muscle cells need a accord of ATP so... This is one of the best esays discussing mitochondria that I have incessantly 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 desire it, how about you?
