Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Some cells, such as human nerve and muscle cells, contain many more mitochondria than do other cells, such as skin cells. Why do some cells have more mitochondria than others?
A
The cells use more energy
B
The cells store more nutrients
C
The cells degrade more proteins
D
The cells divide more frequently
Explanation: 

Detailed explanation-1: -Liver cells contain 1000-2000 mitochondria in each cell. Heart, sperms, and muscle cells contain about 5, 000 mitochondria per cell. These cells need more energy, so they contain more mitochondria than any other organ in the body.

Detailed explanation-2: -Due to their relatively high energy demand, muscle cells require a particularly high number of mitochondria compared to other cell types.

Detailed explanation-3: -Answer and Explanation: Cells that require more energy to function would need to be able to synthesize larger amounts of ATP, the cellular energy. IN order to synthesize more ATP they would need to have more mitochondria.

Detailed explanation-4: -Some different cells have different amounts of mitochondria because they need more energy. So for example, the muscle has a lot of mitochondria, the liver does too, the kidney as well, and to a certain extent, the brain, which lives off of the energy those mitochondria produce.

Detailed explanation-5: -Muscles cells contain more mitochondria because they have to release large amount of energy quickly for movement.
