What is the most important function of mitochondria Quizlet?

The most important function of the mitochondria is to produce energy through the process of oxidative phosphorylation. It is also involved in the following process: Regulates the metabolic activity of the cell. Helps in detoxifying ammonia in the liver cells.

What is mitochondria?

“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?

What is the function of the outer membrane of mitochondria?

The outer membrane covers the surface of the mitochondrion and has a large number of special proteins known as porins. It is freely permeable to ions, nutrient molecules, energy molecules like the ADP and ATP molecules. The inner membrane of mitochondria is rather complex in structure.

What is the role of the mitochondria in the synthesis of ATP?

The enzymes present in the matrix play an important role in the synthesis of ATP molecules. The most important function of mitochondria is to produce energy through the process of oxidative phosphorylation. It is also involved in the following process:

2. Why are mitochondria called the powerhouse of the cell?

Mitochondria are the cell organelles that are responsible for producing ATP, the energy currency of the cell.

3. Briefly describe the structure of mitochondria.

Mitochondria is a rod-shaped, double membraned organelle. It is found both in plant cells and animal cells.

4. What are cristae?

The inner membrane of mitochondria has many folds. These folds form a layered structure called cristae.

5. What is a mitochondrial matrix?

A mitochondrial matrix is a viscous fluid containing a mixture of enzymes, ribosomes, inorganic ions, mitochondrial DNA, nucleotide cofactors, and...

7. State a few mitochondrial disorders.

Alpers disease, Barth syndrome, Kearns-Sayre syndrome.

What is the role of mitochondria in the cell?

Besides this, it is responsible for regulating the metabolic activity of the cell. It also promotes cell multiplication and cell growth. Mitochondria also detox ammonia in the liver cells. Moreover, it plays an important role in apoptosis or programmed cell death. 7. State a few mitochondrial disorders.

What is the main energy molecule used by the mitochondria?

Mitochondria Definition. “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.”.

What is the function of the cristae in the mitochondria?

It has many folds that form a layered structure called cristae, and this helps in increasing the surface area inside the organelle. The cristae and the proteins of the inner membrane aids in the production of ATP molecules.

What is the outer membrane of the mitochondrion made of?

The outer membrane and the inner membrane are made of proteins and phospholipid layers separated by the intermembrane space. The outer membrane covers the surface of the mitochondrion and has a large number of special proteins known as porins.

What is the powerhouse of the cell?

Popularly known as the “ Powerhouse of the cell ,” mitochondria (singular: mitochondrion) are a double membrane-bound organelle found in most eukaryotic organisms.

What is the matrix of mitochondria?

Mitochondrial Matrix. The mitochondrial matrix is a viscous fluid that contains a mixture of enzymes and proteins. It also comprises ribosomes, inorganic ions, mitochondrial DNA, nucleotide cofactors, and organic molecules. The enzymes present in the matrix play an important role in the synthesis of ATP molecules.

Which organelle is responsible for producing ATP?

Mitochondria are the cell organelles that are responsible for producing ATP, the energy currency of the cell. 3. Briefly describe the structure of mitochondria. Mitochondria is a rod-shaped, double membraned organelle. It is found both in plant cells and animal cells. 4.

What is the role of the mitochondrion in eukaryotic cells?

At present the specialists know correctly what role does the mitochondrion play in a eukaryotic cell: it is providing the energy necessary for multiple chemical processes that take place inside. It is possible because these structures are a complex process called cellular respiration.

How powerful are mitochondria?

Mitochondria are very powerful, as they determine many things throughout our lives. However, the most exciting fact about mitochondria is that they were once not a simple structure, but were a part of a separate species:

What is the process of cellular respiration that the mitochondria participate in?

The process of cellular respiration that the mitochondria participate in also generates undesirable by-products. As many reactions in mitochondria require oxygen, the safer form of oxygen gets transformed into so-called reactive oxygen species or ROS:

Do mitochondria have DNA?

As we have already mentioned, mitochondria have their own DNA. It is tiny and carries a few genes. However, mitochondria also produce a lot of ROS that often damage their genomes. It leads to a severe problem:
