mitochondria
how mitochondria are work (explain about mitochondria)
Explain about mitochondria
cell, like other living things require energy to carry out the functions of like. the organelles responsible for energy production are the mitochondria.
these small structures vary widely in shape, frim long and slender to short and fat. the number of mitochondria in a particular cell varies with the cell's energy demands red blood cells lack mitochondria altogether, whereas these organelles may account for 20 percent of the volume of an active liver cell.
most of the chemical reactions that release energy occur in the mitochondria, but most of the cellular activities that require energy occur in the surrounding cytoplasm. cells must therefore store energy in a form that can be moved from placce to place.
Mitochondrial activity requires oxygen, this method of ATP production is known as aerobic metabolism aerobicmetabolism in mitochondria produces about 95 percent of ATP needed to keep a cell alive.
They make energy.

function
- Mitochondria generate chemical energy, similar to the type of energy you get from a battery. The energy made by the mitochondria is in the form of a chemical called adenosine triphosphate or ATPfor short. ATP is an energy currency that every cell in our body can use and it keeps us alive.
- Mitochondria are crucial to help preserve this environment and their most valuable contribution to this process is that they take up calcium. Calcium is important within cells as a signalling molecule mitochondria store calcium and release it when it is required. Too much free calcium within the cell would be detrimental to the finely tuned regulation of processes within the cell.
Why is mitochondrial DNA important?
Mitochondrial DNA contains vital information that allows the mitochondria to make the proteins it needs to make energy. It contains 37 genes compared to the thousands of genes found within the chromosomes, but all these genes are vital for making the mitochondria and hence our cells work properly. None of the genes within the mitochondrial DNA control your appearance but when these genes contain mistakes (mutations) because of the important job that mitochondria do they cause disease.
