There are 136 muscle cell profiles in the bundle at this level, 11 nuclei and 765 mitochondria. The sectional area of each muscle cell profile (minus the nucleus) and of each mitochondrion was measured, in order to obtain the mitochondrial spatial density.

Muscle cells are assiciated with a large number of mitochondria as they require more ATP (energy) to function than other cells. They need this because of their frequent contraction and relaxation, which requires more ATP than average cells.

Muscles cells contain a large number of mitochondria because muscle tissues require a large amount of energy for movement and especially during exercise. Since ATP is produced by mitochondria, muscles cells have a large number of mitochondria to fulfill the energy requirements.

Cellular respiration occurs in mitochondria. Therefore, cells that are more active usually contain more mitochondria than cells that are not as active. Since muscle cells are required for the movement of an organism, they will have more mitochondria than skin cells.

Muscle cells require much more energy than the rest of the body, so the muscles contain more mitochondria. Your fat cells have many mitochondria because they store a lot of energy. Muscle cells have many mitochondria, which allows them to respond quickly to the need for doing work.

Aerobic exercise uses oxygen, which directly relates to how the mitochondria function. The more oxygen you pump to your muscle cells and their mitochondria through aerobic workouts, the faster and better they work to produce energy. There is also an increase in mitochondrial enzymes.

During strenuous exercise, the rate of energy use in skeletal muscles can increase by more than 100-fold almost instantly. 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.

The liver is a central organ for the homeostasis of carbohydrates, lipids and proteins metabolism. In this context, hepatocyte mitochondria are essential in regulating the flux of metabolites in the cell in order to adjust energetic demand, ammonia detoxification, or anabolic pathways.

Ogata and Yamasaki used electron microscopy to provide the first detailed description of mitochondrial localization in adult mammalian skeletal muscle (Ogata and Yamasaki, 1985). These studies revealed that mitochondria are located within the I-band, adjacent to the CRU on either side of the Z-line.

Answer: Some cells have more mitochondria than others. Your fat cells have many mitochondria because they store a lot of energy. Muscle cells have many mitochondria, which allows them to respond quickly to the need for doing work.

A. Your heart muscle cells – with about 5,000 mitochondria per cell. These cells need more energy, so they contain more mitochondria than any other organ in the body!

If mitochondria are present at almost half the synapses (Shepherd and Harris, 1998) and throughout several meters of axon, an estimated population of 2 million mitochondria per cell is reasonable.

Mitochondria are highly dynamic organelles that divide, fuse, and move purposefully within axons and dendrites. Major functions of mitochondria in neurons include the regulation of Ca2+ and redox signaling, developmental and synaptic plasticity, and the arbitration of cell survival and death.

The head of the sperm cell contains the haploid chromosome complement for the species in question. The sperm’s midpiece contains many mitochondria so that a supply of energy is available for the sperm to perform its function of traveling to and later fertilizing the egg.

In sexual reproduction, paternal mitochondria found in the sperm are actively decomposed, thus preventing “paternal leakage”. Mitochondria in mammalian sperm are usually destroyed by the egg cell after fertilization.

midpiece

A tenet of elementary biology is that mitochondria — the cell’s powerhouses — and their DNA are inherited exclusively from mothers.

The typical mammalian sperm midpiece contains approximately 50–75 mitochondria with one copy of mtDNA in each.

Interesting facts about our incredible mitochondria: there are about 10 million billion (100,000 trillion) mitochondria in an adult human! about 2 billion mitochondria are made every second throughout a person’s life.

You inherited your mitochondrial DNA from your mother, who inherited hers from her mother and so forth. Maternal inheritance also gave rise to the idea that there exists a “Mitochondrial Eve,” a woman from whom all living humans inherited their mitochondrial DNA.

Specifically, your mom’s—and your—mitochondria. The Supporting Evidence: The mitochondria is a tiny—but powerful—part of a cell. It’s responsible for the cell’s respiration and energy production processes. And, mitochondrial DNA (or mDNA) is inherited strictly from the mom.

The mitochondria, and thus mitochondrial DNA, are passed exclusively from mother to offspring through the egg cell.
