Where is the mitochondria in an animal cell?
cytoplasm
Mitochondria are located in the cytoplasm of cells along with other organelles of the cell.
Why is mitochondria in animal cells?
Mitochondria are rod-shaped organelles that can be considered the power generators of the cell, converting oxygen and nutrients into adenosine triphosphate (ATP). This process is called aerobic respiration and is the reason animals breathe oxygen. …
What is the best definition of mitochondria?
mitochondria. See word origin. Frequency: A spherical or elongated organelle in the cytoplasm of nearly all eukaryotic cells, containing genetic material and many enzymes important for cell metabolism, including those responsible for the conversion of food to usable energy.
What is the main function of mitochondria?
Mitochondrion, membrane-bound organelle found in the cytoplasm of almost all eukaryotic cells (cells with clearly defined nuclei), the primary function of which is to generate large quantities of energy in the form of adenosine triphosphate (ATP).
What is the structure of the mitochondria in an animal cell?
Mitochondria have an inner and outer membrane, with an intermembrane space between them. The outer membrane contains proteins known as porins, which allow movement of ions into and out of the mitochondrion.
What is an example of a mitochondria?
Mitochondria are typically round to oval in shape and range in size from 0.5 to 10 μm. 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.
What is mitochondria and its functions?
Mitochondria Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
What are the functions of a mitochondria?
Mitochondria are well known as the powerhouse of the cell, and as discussed in the section on Generation of ATP: Bioenergetics and Metabolism, in an active tissue such as heart, they are responsible for generating most of the ATP in the cell.
What is the role of mitochondria in animal cells?
What is the role of mitochondria in animal cells? Mitochondria are organelles which provide the energy used up by the cell in respiration, through producing molecules called ATP. Some cells have loads of mitochondria, and other cells have very little.
Where does the word mitochondrion come from in biology?
The word mitochondrion comes from the Greek μίτος, mitos, “thread”, and χονδρίον, chondrion, “granule” or “grain-like”. Mitochondria generate most of the cell’s supply of adenosine triphosphate (ATP), used as a source of chemical energy. A mitochondrion is thus termed the powerhouse of the cell.
Where are mitochondria located in an eukaryotic cell?
“Mitochondria are membrane-bound organelles present in the cytoplasm of all eukaryotic cells, that produces adinosine triphosphate (ATP), the main energy molecule used by the cell.” Read on to explore what is mitochondria, its structure, and functions. What is Mitochondria?
Why are mitochondria called the powerhouse of the cell?
Mitochondria are a membrane-bound organelle present in the cytoplasm of all eukaryotic cells. It is responsible for producing Adenosine triphosphate (ATP), the main energy currency of the cell. 2. Why are mitochondria called the powerhouse of the cell?
