Tissues and organs that need a lot of energy have large numbers of mitochondria in their cells. For example, liver cells and muscle cells contain a lot of mitochondria. Muscle cells are assiciated with a large number of mitochondria as they require more ATP (energy) to function than other cells.
As muscle cells have a high demand for energy (due to their function), they have a large number of mitochondria in order to meet their energy needs. … Muscle cells are assiciated with a large number of mitochondria as they require more ATP (energy) to function than other cells.
The liver is extremely rich in mitochondria due to its critical metabolic function in the body, with each hepatocyte containing 1000–2000 mitochondria9.
For technical reasons, many of these biochemical studies have been performed with mitochondria purified from liver; each liver cell contains 1000–2000 mitochondria, which in total occupy about one-fifth of the cell volume.
Since liver cells are highly regenerative and muscle cells spend high energy in contraction and expansion, these cells require high energy. Hence, presence of large number of mitochondria in liver cells and muscle cells is justified.
The number of mitochondria per cell varies widely—for example, in humans, erythrocytes (red blood cells) do not contain any mitochondria, whereas liver cells and muscle cells may contain hundreds or even thousands. The only eukaryotic organism known to lack mitochondria is the oxymonad Monocercomonoides species.
Muscles cells contain more mitochondria because they have to release large amount of energy quickly for movement.
What cells have the most mitochondria? 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!
The analysis of their ultrastructural morphology showed that liver connective tissue cells and smooth muscle cells developed cytoskeletal and cytoplasmic organelle polarities, in response to the contact with gel surface.
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.
In fat metabolism the liver cells break down fats and produce energy. They also produce about 800 to 1,000 ml of bile per day. This yellow, brownish or olive green liquid is collected in small ducts and then passed on to the main bile duct, which carries the bile to a part of the small intestine called the duodenum.
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.
Muscles cells contain more mitochondria because they have to release large amount of energy quickly for movement.
Interesting facts about our incredible mitochondria: each mitochondrion contains 17,000 tiny assembly lines for making ATP (energy) mitochondria are responsible for creating more than 90% of the energy needed to sustain life and support organ function. heart muscle cells contain about 5,000 mitochondria per cell.
A good example is exercise: We know that prolonged exercise can stimulate muscle cells to produce more mitochondria that will then help them meet their future energy needs. Like your cells, mitochondria can duplicate themselves to make more in a process called mitochondrial biogenesis.
What type of cell is likely to have the most mitochondria? Cells that need to perform high amounts of work, such as muscle cells in the heart and legs, fat cells and liver cells.
The same is true for smooth muscle; however, due to a combination of a reduced requirement to perform work and greater efficiency of contraction, smooth muscle would be expected to contain fewer mitochondria than skeletal and cardiac muscles.
A new study found that exercise — and in particular high-intensity interval training in aerobic exercises such as biking and walking — caused cells to make more proteins for their energy-producing mitochondria and their protein-building ribosomes, effectively stopping aging at the cellular level.
Muscle cells have the most number of mitochondria in a human body. That includes the cardiac cells as well(because, the heart is also a muscular chamber, if you’re not familiar). Their energy demand is very high compared to the other cells in the body, due to constant contraction and elongations.
In the study, researchers demonstrate that when the liver makes fat through lipogenesis, a signal is sent to skeletal muscle cells to burn fat through fatty acid oxidation. The fat-making process in the liver is controlled by PPAR delta, while the fat-burning process in muscle is controlled by PPAR alpha.
In NAFLD, given the role of muscle in energy metabolism, muscle loss promotes disease progression. However, liver damage may be directly responsible of this muscle loss. Indeed, muscle homeostasis depends on the balance between peripheral availability and action of anabolic effectors and catabolic signals.
Smooth muscle fibers are located in walls of hollow visceral organs (such as the liver, pancreas, and intestines), except the heart, appear spindle-shaped, and are also under involuntary control.
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.
Muscle cells have numerous mitochondria, more than other types of cells, so that they can quickly and forcefully respond to the body’s constant need for various types of movement.
One of the detoxifying functions of hepatocytes is to modify ammonia into urea for excretion. The most abundant organelle in liver cells is the smooth endoplasmic reticulum.
The primary role of the liver is in the regulation of the metabolism of amino acids and proteins. The liver carries out four main functions in protein metabolism: formation of plasma proteins, amino acid interconversion, deamination of amino acids and urea synthesis (for ammonia excretion).
Liver. The liver has many functions, but its main job within the digestive system is to process the nutrients absorbed from the small intestine. Bile from the liver secreted into the small intestine also plays an important role in digesting fat and some vitamins.
Your liver continually produces bile. This is a chemical that helps turn fats into energy that your body uses. Bile is necessary for the digestive process.
Terms in this set (46) Why do large cells need more mitochondria? … Mitochondria is place for cellular respiration. More mitochondria = more ATP produced.
Mitochondria supply the cell with ATP (Adenosine Triphosphate), which is the energy the cell needs. A heart cell is a type of muscle cell which needs plenty of energy to contract and keep functioning. This is why a heart cell needs more mitochondria than other cells- because they need more energy.
Fat cells have many mitochondria as well, but fat cells store a lot of energy. Since the muscle cell is an active call, it requires more energy and therefore has more mitochondria compared to the less active fat cell.
What cells have the most mitochondria? 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!
The extraocular muscles have, arguably, the highest mitochondrial content of all mammalian skeletal muscles.
Explanation: Neurons have more extended and complex shapes than other cells and consequently face a greater challenge in distributing and maintaining mitochondria throughout their arbors. … The axon in the nodal region usually contains concentrations of organelles, especially mitochondria.
