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: -This function is so important that mitochondria can take up as much as 25% of the cell volume. Cells contain from 1000 to 2500 mitochondria.

Detailed explanation-3: -The four complexes of the mitochondrial respiratory chain are critical for ATP production in most eukaryotic cells.
