Do ciliated epithelial cells have mitochondria?
Ciliated cells are located, with a small portion of cytoplasm, on the basement membrane and reach through the basal cells to the epithelial surface. In the cytoplasm, numerous mitochondria are formed; these mitochondria are found in apical cell locations and have an elongated configuration.
Which tissue has the highest number of mitochondria?
heart muscle cells
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!
What is special about ciliated epithelial cells?
Cilia are tiny hair like structures on the surface of the cell. The hairs sweep hair, mucus, trapped dust and bacteria up to the back of the throat where it can be swallowed.
Why do epithelial cells in the small intestine have a lot of mitochondria?
In particular the epithelial cells lining the small intestine. They will therefore have a large surface area provided by the microvilli and due to the need for active transport across their cell membranes they will contain a large number of mitochondria providing them with ATP.
Why do epithelial cells need mitochondria?
Mitochondria are able to modulate cellular ROS content within the enterocytes, and thus have a fundamental role in epithelial homeostasis by controlling apoptosis process and, finally, intestinal cell fate.
Why do cells have many mitochondria?
This is because mitochondria produce ATP during aerobic respiration and ATP is needed for muscle to contract. Without the mitochondria the muscle wouldn’t be able to contract. Muscles cells contain more mitochondria because they have to release large amount of energy quickly for movement.
Where would you find large numbers of mitochondria?
In cells where there is a high energy demand large numbers of mitochondria are found. The tail of a sperm contains many mitochondria and they run in a spiral like form along the length of the tail. In heart muscle cells about 40% of the cytoplasmic space is taken up by mitochondria.
Which type of cells would most likely have the largest number of mitochondria?
It is generally believed that the cells that have the most mitochondria in them are the muscle cells.
What is the purpose of the ciliated epithelial cell?
Ciliated epithelium performs the function of moving particles or fluid over the epithelial surface in such structures as the trachea, bronchial tubes, and nasal cavities. It often occurs in the vicinity of mucus-secreting goblet cells.
Why is mitochondria important in epithelial cells?
What does mitochondria do in small intestine?
Mitochondria present in cells of the inner intestinal wall control the renewal of this organ’s surface and may contribute to the development of gut diseases, according to a new study published in the journal Nature Communications.
Why do epithelial cells have so many mitochondria?
Answer and Explanation: Epithelial cells have many mitochondria because these cells have high levels of energy output and require the ATP produced by the mitochondria.
How does the ciliated epithelium create movement?
Ciliated epithelium creates movement by using cilia which is one of the examples cytoskeleton system. It is a well known fact that cytoskeleton components derive their energy from ATP hydrolysis which are mainly synthesized in mitochondria with the help of electron transport system.
Why does the human sperm cell have lots of mitochondria?
Why does the human sperm cell have lots of mitochondria? By Zaira Salvador. Mitochondria supply energy to the sperm cells and are responsible for carrying out the process of respiration, necessary to provide the tail (flagellum) with the energy supply that it needed to allow the sperm cell to swim towards the egg.
Where does the energy produced by mitochondria go?
Put simply, mitochondria are cell organelles linked to the membrane which work to generate enough chemical energy necessary to fuel the biochemical reactions of the cell. The chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate.
