What is the function of the word mitochondria?
Table of Contents
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 10 functions of mitochondria?
More about each of these functions of mitochondria follows below.
- ATP Synthesis. Release of energy to fuel cell activity.
- Production of heat. Non-shivering thermogenesis.
- Role as independent units within eukaryotic cells. Mitochondria have mitochondrial DNA (mtDNA)
- Role in apoptosis. Programmed cell death.
- Storage of Ca2+ ions.
How does the structure of mitochondria relate to its function?
The structure of the mitochondrion is adapted to the function it performs: Outer membrane – the outer membrane contains transport proteins that enable the shuttling of pyruvate from the cytosol. Inner membrane – contains the electron transport chain and ATP synthase (used for oxidative phosphorylation)
How is the structure of a mitochondria important for its function?
The folding of the inner membrane increases the surface area inside the organelle. Since many of the chemical reactions happen on the inner membrane, the increased surface area creates more space for reactions to occur. If you have more space to work, you can get more work done.
What are the parts of mitochondria and its function?
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 the function of mitochondria in cells apex?
The main job of mitochondria is to perform cellular respiration. This means it takes in nutrients from the cell, breaks it down, and turns it into energy.
What are the major parts of mitochondria and its function?
The parts of the mitochondria are the outer membrane, intermembrane space, inner membrane, and matrix. The mitochondria function to produce the chemical energy required to fuel biochemical reactions in the cell.
What is mitochondria and its function Class 9?
Mitochondria are round “tube-like” organelles that provide energy to a cell in the form of ATP (Adenosine Triphosphate) for performing different chemical activities for the sustainance of life.
What is the function of mitochondria Class 11?
Mitochondria are the sites of aerobic respiration and produce cellular energy in the form of ATP, hence they are called ‘power houses’ of the cell. The matrix also possesses single circular DNA molecule, a few RNA molecules, ribosomes, and a few components of protein synthesis.
