AP BIOLOGY

Detailed explanation-1: -To meet this energy demand, muscle cells contain mitochondria. These organelles, commonly referred to as the cell’s “power plants, ” convert nutrients into the molecule ATP, which stores energy.

Detailed explanation-2: -The organelle that is abundant in muscles is the mitochondrion. Mitochondria are numerous in muscle cells to ensure that there is enough energy produced to meet the usual high demands of muscle activity such as contraction.

Detailed explanation-3: -Of all the cells in human body, its the heart muscle cells with about 5, 000 mitochondria per cell that contain far more mitochondria than any other organ in human body. The number of mitochondria reflects the energy requirement of a cell. Heart muscle cells have extra-special demand for ATP to keep the heart pumping.

Detailed explanation-4: -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-5: -Mitochondria Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
