Because some cells are bigger and hungrier :D The number of mitochondria a cell contains depends on how much energy the cell needs to produce. Muscle cells for example, contain more number of mitochondria compared to kidney cells. In addition, the number of mitochondria in a cell is not a constant. It varies depending on the physical activity of an individual. To give you an example, it has been observed that marathon runners have more number of mitochondria in their leg muscle cells than people with desk jobs.
There may be some leakage of the high energy electrons in the respiratory chain to form reactive oxygen species, this will cause the mitochondria (which creates energy for the cell) to be different in the cells of older people. The mitochondria generates energy for the cell, so as you age there may be some leakage of the energy that the mitochondria generates.
Aging is associated with progressive mitochondrial dysfunction that occurs due to the accumulation of mitochondrial DNA (mtDNA) mutations and increased reactive oxygen species (ROS) production that causes oxidative damage to cellular macromolecules.
The mitochondria. In plant cells the chloroplast makes energy also.
Oxidative phosphorylation in the mitochondria in cells
it isn't the cells that make peoples races different it is there DNA that makes people black or white
The organelle responsible for producing energy in cells is the mitochondria. Through a process called cellular respiration, mitochondria generate adenosine triphosphate (ATP), which serves as the main energy currency in cells.
Mitochondria! Remember this: The mitochondria is like a powerhouse of the cell. It makes and provides ATP that provides energy. This organelle is very important. If not anything else about mitochondria, at least always remember that it makes energy
Makes and stores energy.
The mitochondria. In plant cells the chloroplast makes energy also.
Mitochondria, an organelle in eukaryotic cells makes the cells main energy source ATP. Basically the Mitochondria are the powrhouses of a cell that keep it running.
Mitochondria or mitochondrion
It's a very important organelle in cells because the mitochondria is what makes the energy for the cell. :D
Mitochondria makes the energy and the cytoplasm transports it throughout the cell
The mitochondria is what produces energy. It makes it ATP.
it isn't the cells that make peoples races different it is there DNA that makes people black or white
The mitochondria.
Oxidative phosphorylation in the mitochondria in cells
Plant cells make energy for the cell and makes sugars that feed the plant to do it! This sections has to do somthing with a certain part that is called the mitochondria..
The mitochondria ( Singular: Mitochondrion) is often called a cells power plant. This is because it makes the cells energy.
