Why does a muscle cell contain many mitochondria?

Respiration takes place in the mitochondria of cells in order to provide the cell with energy. 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.

Bearing this in mind why do muscle cells have far more mitochondria than bone cells?

Explanation: Muscle cells need energy to do mechanical work and respond quickly. Thus a higher number of mitochondria is present so that the cells requirement of energy to perform its specific function is fulfilled.

Keeping this in mind why do muscle cells have more mitochondria than fat cells?

The ATP is produced in the mitochondria using energy stored in food. 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.

Besides, why might muscle cells need more mitochondria than other animal cells?

Mitochondria are tiny organelles that transfer energy from organic molecules to adenosine triphosphate (ATP). Propose: Muscle cells have more mitochondria then other cells because bodies are constantly using their muscles to move, so the muscle cells need more mitochondria.

Do muscle cells have more mitochondria?

Muscles cells contain more mitochondria because they have to release large amount of energy quickly for movement.

What simple sugar is broken down in the mitochondria?

Glucose is a simple sugar that is broken down in the mitochondria.

What vitamins help mitochondria?

Several vitamins and (trace) minerals are essential for mitochondrial functioning, either by acting as cofactors in energy metabolism and/or by acting as antioxidants.
3.1. B vitamins
  • Thiamine (vitamin B1)
  • Riboflavin (vitamin B2)
  • Cobalamin (vitamin B12)
  • Other B vitamins.

What are the sources of ATP for muscle contraction?

ATP is required for muscle contraction. Four sources of this substance are available to muscle fibers: free ATP, phosphocreatine, glycolysis and cellular respiration. A small amount of free ATP is available in the muscle for immediate use.

Which type of muscle can contract without being stimulated by the nervous system?

Most Smooth Muscle Cells can CONTRACT WITHOUT Nervous Stimulation. Because most of its movements cannot be consciously controlled, Smooth Muscle is referred to as Involuntary Muscle.

What are the 4 types of muscles?

Muscle Types
  • Skeletal Muscle. Skeletal muscle, attached to bones, is responsible for skeletal movements.
  • Smooth Muscle. Smooth muscle, found in the walls of the hollow internal organs such as blood vessels, the gastrointestinal tract, bladder, and uterus, is under control of the autonomic nervous system.
  • Cardiac Muscle.

Which muscle cells have the greatest ability to regenerate?

Cardiac muscle can also hypertrophy. However, there are no equivalent to cells to the satellite cells found in skeletal muscle. Thus when cardiac muscle cells die, they are not replaced. Smooth cells have the greatest capacity to regenerate of all the muscle cell types.

Which cell has the most mitochondria?

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!

Where are mitochondria located in muscle cells?

Electron microscopy provides pictorial evidence that mitochondria are largely localized in distinct regions of the muscle, below the sarcolemma, termed subsarcolemmal (SS) mitochondria, and between the myofibrils, called intermyofibrillar (IMF) mitochondria.

Which type of muscle tissue is striated?

Muscle tissue can be categorized into skeletal muscle tissue, smooth muscle tissue, and cardiac muscle tissue. Skeletal muscle fibers are cylindrical, multinucleated, striated, and under voluntary control. Smooth muscle cells are spindle shaped, have a single, centrally located nucleus, and lack striations.

Which of the following is an accurate comparison of skeletal muscle to smooth muscle?

Which of the following is an accurate comparison of skeletal muscle to smooth muscle? Smooth muscle contracts more slowly but relaxes more rapidly. Smooth muscle contracts more rapidly but relaxes more slowly.

What is the most distinguishing characteristic of muscle tissue?

Ch 9 practice exam muscles and muscle tissues
QuestionAnswer
what is true about isotonic contraction?Muscle tension remains relatively constant.
What is the most distinguishing characteristic of muscle tissue?Its ability to transform chemical energy into mechanical energy.

Which type of muscle has more mitochondria?

Slow-twitch muscle fibers are fatigue resistant, and focused on sustained, smaller movements and postural control. They contain more mitochondria and myoglobin, and are aerobic in nature compared to fast-twitch fibers. Slow-twitch fibers are also sometimes called type I or red fibers because of their blood supply.

Which muscles can contract without the need?

Some muscles (skeletal muscles) will not contract unless stimulated by neurons; other muscles (smooth & cardiac) will contract without nervous stimulation but their contraction can be influenced by the nervous system.

Which of the following individuals would have more mitochondria in her skeletal muscle?

Physiology Exam 1
QuestionAnswer
Which of the following best describes the resting membrane potential (RMP)?The intracellular environment is negatively charged
Which of the following individuals would have more mitochondria in her skeletal muscle?A 22-year-old soccer player

Which cell has less mitochondria?

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.

What are the 3 muscle types found in the body?

The three main types of muscle include skeletal, smooth and cardiac.

How do I know my muscle fiber type?

The only 100% accurate reading of a muscle fiber type is through a muscle biopsy, but if you're looking for a practical test that can be done in less than a minute, I highly suggest you use the vertical jump test.

Which of the following is not a function of skeletal muscle?

So, the correct answer is 'Production of body heat.

Why are there so many mitochondria in a cell?

In return the host cell provides physical protection and a constant supply of food and oxygen. Mitochondrial cells divide using their own circular strand of DNA and as a result there can be many mitochondria in one cell. In cells where there is a high energy demand large numbers of mitochondria are found.

What do skeletal muscle cells have more of than other cells?

Skeletal muscle cells form elongated fibers in the body. They have multiple nuclei within each cell. This contrasts with the majority of other cells in human bodies. They also contain many mitochondria, cellular organelles that produce adenosine triphosphate (ATP), the body's fuel.

What are the 3 main categories of muscle fibers?

The 3 types of muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striated, and are under involuntary control.

What are the two most important pathways by which ATP is generated in muscle cells?

Muscle cells are able to produce ATP with oxygen, which is called aerobic respiration, or without oxygen, an anaerobic process called anaerobic glycolysis or fermentation.

What do mitochondria do in muscle cells?

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.

Which type of muscles can you control?

Skeletal Muscle
Skeletal muscles are voluntary muscles, which means you can control what they do.

What kind of neuron sends a signal to a muscle?

Motor neurons are responsible for voluntary control of the muscles all over the body. The operation of the nervous system depends on how well neurons communicate. For an electrical signal to travel between two neurons, it must first be converted to a chemical signal.

Do cardiac muscle cells have mitochondria?

Cardiac muscle cells have more mitochondria, as they are more reliant on aerobic respiration than skeletal muscle.
