Why do muscle cells have more mitochondria than fat cells?

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.

Why do larger cells need more mitochondria?

Why do large cells need more mitochondria? Need more energy. Mitochondria is place for cellular respiration. More mitochondria = more ATP produced.

Do skeletal muscles have multiple mitochondria?

A skeletal muscle contains multiple fascicles – bundles of muscle fibers. Each individual fiber and each muscle is surrounded by a type of connective tissue layer of fascia. … Muscle fibers also have multiple mitochondria to meet energy needs. Muscle fibers are in turn composed of myofibrils.

Why does a muscle cell contain many mitochondria Why does a white blood cell contain many lysosomes?

Muscle cells contain many mitochondria because muscle burn more energy so the cells need more mitochondria to make more energy. White blood cells have more lysosomes because they are used to fight infection. Lysosomes get rid of waste so the white blood cells have more so they can get rid of infections.

How many mitochondria do muscle cells have?

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. mitochondrial DNA can mutate up to 10x faster than nuclear DNA in an ordinary cell. mitochondria use over 90% of the oxygen we breathe.

What organelle would you expect a muscle cell to have a lot of and why?


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.

Why do mitochondria have two membranes?

The double membrane found in mitochondria and chloroplasts appears to be a relic of the absorption of the prokaryotic bacteria by the eukaryotic host cells. The inner membrane which now contains numerous folds apparently came from the bacterial membrane while the outer membrane came from the host cell itself.

Which cell — a fat cell or a muscle cell would have more mitochondria?

Muscle cells require large amounts of energy in order to function properly. Muscle cells contain more mitochondria within their cells and these…

How do some cells have more mitochondria?

Logically mitochondria multiply when a the energy needs of a cell increase. Therefore power-hungry cells have more mitochondria than cells with lower energy needs. For example repeatedly stimulating a muscle cell will spur the production of more mitochondria in that cell to keep up with energy demand.

Why are muscle cells Multinucleated?

Skeletal muscles generate heat as a byproduct of their contraction and thus participate in thermal homeostasis. … The cells are multinucleated as a result of the fusion of the many myoblasts that fuse to form each long muscle fiber. Cardiac muscle forms the contractile walls of the heart.

Why do cardiomyocytes have larger mitochondria and more mitochondria than skeletal muscle fibers?

Cardiac muscle cells contain many more mitochondria than skeletal muscle cells in order to generate the energy needed to power contraction. Cardiac muscle is said to be involuntary as you can’t voluntarily cause it to contract which you can with skeletal muscle.

Which cells contain more 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!

Why do fat cells have few mitochondria?

I only need a little energy which i get from a small amount of food in the way that fat cells only a little energy which they get from a small number of mitochondria. … This is because mitochondria produce ATP during aerobic respiration and ATP is needed for muscle to contract.

What can we infer about the total quantity of mitochondria in a muscle cell versus a skin cell?

There are more mitochondria in muscle cells than there are in skin cells. … Cells that are more active and/or move more will require a greater energy produced via cellular respiration. Therefore cells that are more active usually contain more mitochondria than cells that are not as active.

Why does skeletal muscle have so many nuclei?

Skeletal muscle fibers are multinucleate because they are sincitios. … Skeletal muscle cells arise in embryo as uninucleated entities. Later the myoblasts cells fuse together and give rise to multinucleated muscle fiber therefore have multiple nuclei (each nucleus originating from a single myoblast).

Where are mitochondria located in muscle cells?

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.

What does a represent in the mitochondria figure above?

This figure shows above shows the relationship between chloroplasts and mitochondria. The letters “a” and “e” represent the products of photosynthesis that are needed as reactants for cellular respiration. … Cellular respiration would continue using glycerol fatty acids and amino acids as an energy source.

What is the function of the two membranes of mitochondria quizlet?

What is the function of the two membranes of mitochondria? Protons are pumped into the space between the membranes. What is the role of oxygen in respiration?

Which of the following best describes the role the double membrane plays in the mitochondria?

Which of the following best describes the role the double membrane plays in the mitochondria? The double membrane structure creates two sets of membranes to embed proteins into for cellular respiration.

What is the function of mitochondria in a muscle cell?

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.

Why do skin cells have fewer mitochondria than muscle cells?

Skin cells would contain fewer mitochondrias than muscle cells. Skin cells function in protection whereas muscle cells function in movement requiring energy. Muscle cells convert energy into motion therefore more mitochondria would be found in muscle cells.

Why is the mitochondria the most important organelle?

As the power plants in virtually every human cell (as well as animal plant and fungi cells) mitochondria play an essential role in creating energy to drive cellular function and basically all of our biological processes.

Why do some cells have mitochondria?

Mitochondria are essential components of nearly all cells in the body. These organelles are the powerhouses for cells providing energy to carry out biochemical reactions and other cellular processes. Mitochondria make energy for cells from the chemical energy stored in the food we eat.

Why mitochondria is a cell within a cell?

Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. … It is for this reason that mitochondria are often referred to as the powerhouses of the cell. Cells that need a lot of energy like muscle cells can contain thousands of mitochondria.

What is the explanation for multiple nuclei in skeletal muscle fibers?

Muscle fibers form from the fusion of embryonic myoblast cells and satellite cells thus each fiber contains multiple nuclei. Because muscle fibers are so long many copies of DNA are needed to keep the cell functioning.

Why is the Multinucleate condition important in skeletal muscle fibers?

Why is the multinucleate condition important in skeletal muscle fibers? It’s so long it has to have multiple nuclei. The time of a murder victims death is commonly estimated by the flexibility of the Body.

How could multinucleated cells be explained?

Certain cell types normally have several nuclei per cell. How could such multinucleated cells be explained? The cell underwent repeated mitosis but cytokinesis did not occur. … In animal cells Taxol prevents microtubule depolymerization.

Why are mitochondria larger and more numerous in cardiac muscle tissue?

Cardiac muscle cells contain larger amounts of mitochondria than other cells in the body enabling higher ATP production. … Myoglobin transfers oxygen from the blood to the muscle cell and stores reserve oxygen for aerobic metabolic function in the muscle cell.

What does the difference in mitochondrial concentration most likely indicate about cardiac muscle cells?

What does the difference in mitochondrial concentration most likely indicate about cardiac muscle cells compared with skeletal muscle cells? … Cardiac muscle cells have a lower release rate of carbon dioxide into veins. Cardiac muscle cells require a larger supply of energy released through respiration.

Which muscle would have the most mitochondria in the muscle fibers?

Slow-twitch muscle fibers

Slow-twitch muscle fibers have high concentrations of mitochondria and myoglobin. Although they are smaller than the fast-twitch fibers they are surrounded by more capillaries (1 2).
