How does the structure of the mitochondria affect its function?
Mitochondria are shaped perfectly to maximize their productivity. They are made of two membranes. 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.
Why is the structure of mitochondria important?
The cristae greatly increase the total surface area of the inner membrane. The membranes create two compartments. The intermembrane space, as implied, is the region between the inner and outer membranes. It has an important role in the primary function of mitochondria, which is oxidative phosphorylation.
What are the structures associated with the main function of the 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 is the structure of mitochondria?
Mitochondria have a double membrane arrangement which separates the organelle into four distinct compartments – the outer membrane, the intermembrane space, the inner membrane, and the matrix. Each compartment serves different functions.
What are 2 characteristics of mitochondria?
Characteristics of Mitochondria (i) The mitochondria are sausage-shaped or cylindrical having a diameter of 0.2-1.0 µm and average 0.5 µm and length 1.0-4.1 µm. (ii) Each mitochondrion is a double membrane bound structure. (iii) The inner compartment is called the matrix.
What is the role of mitochondria for Class 9?
1)They are sites of cellular respiration. 2)They uses oxygen to oxidise carbohydrates and fats present in the cell to carbon dioxide and water. Since mitochondria synthesises energy rich compound ATP it is called powerhouse of cell.
Why is the structure of the inner membrane of the mitochondria important to its function?
The inner membrane is also loaded with proteins involved in electron transport and ATP synthesis. This membrane surrounds the mitochondrial matrix, where the citric acid cycle produces the electrons that travel from one protein complex to the next in the inner membrane.
What is the main function of mitochondria of the cell?
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 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).
How is the structure of the mitochondria related to its function?
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. The inner membrane is strictly permeable only to oxygen and to ATP molecules.
How is the inner membrane of mitochondria permeable to oxygen?
The cristae and the proteins of the inner membrane aids in the production of ATP molecules. The inner membrane is strictly permeable only to oxygen and to ATP molecules. A number of chemical reactions take place within the inner membrane of mitochondria. The mitochondrial matrix is a viscous fluid that contains a mixture of enzymes and proteins.
How big is a mitochondrion in a cell?
Mitochondria (singular: mitochondrion) are double membrane-bound cell organelles with a typical size of 0.75-3 μm². They are found in most mammalian cells, with notable exceptions including mature erythrocytes.
How does the cristae increase the surface area of the mitochondrial membrane?
The cristae increase the surface area inside the mitochondrial membrane in order to generate ATP molecules efficiently. The larger the surface, the more the space to carry out cell functions. The surface of the cristae has oxysomes attached to it, which aids the osmosis of ions.

How is actin related to the movement of mitochondria?
This would imply that there is a signal, like an intracellular “chemo attractant” that at the same time directs movement of mitochondria and recruits the fission machinery to prepare mitochondria for their transport. Actin would then act as an active track to move the transportable organelle towards their destination.
How are mitochondria regulated by the cytoskeletal system?
A growing body of evidence suggests that mitochondria use cytoskeletal proteins as tracks for their movement; in turn, mitochondrial morphology and function is regulated via mostly uncharacterized pathways, by the cytoskeleton. 1. Introduction Mitochondria are essential organelles for life and death of the cell.
