MICROANATOMY

Detailed explanation-1: -The number of mitochondria in a cell depends on the cell’s function. Cells with particularly heavy energy demands, such as muscle cells, have more mitochondria than other cells. The main function of the mitochondria is to provide energy for cellular activity by the process of aerobic respiration.

Detailed explanation-2: -Mitochondria have an important role in cellular respiration through the production of ATP, using chemical energy found in glucose and other nutrients.

Detailed explanation-3: -Within eukaryotic cells, mitochondria function somewhat like batteries, because they convert energy from one form to another: food nutrients to ATP. Accordingly, cells with high metabolic needs can meet their higher energy demands by increasing the number of mitochondria they contain.

Detailed explanation-4: -The mitochondrion performs most cellular oxidations and produces the bulk of the animal cell’s ATP. The mitochondrial matrix contains a large variety of enzymes, including those that convert pyruvate and fatty acids to acetyl CoA and those that oxidize this acetyl CoA to CO2through the citric acid cycle.
