Why the inner membrane of mitochondria is deeply folded Class 9?
Written by Michael Henderson — 1 Views
Answer. →The inner membrane of the mitochondria is folded to make more surface area where chemical reactions can take place. The more the folds, the bigger the surface. These folds are called cristae.
Also question is, what is the use of deep folding in the inner membrane of mitochondria?
Answer. The infoldings or inward projections of inner membrane of mitochondria are called cristae. They increase the surface area for chemical reactions to occur like cellular respiration. F1 particles of cristae have some oxidative enzymes called oxysomes.
Likewise, why is inner membrane of mitochondria folded and why is it able to make its own protein? The inner membrane is highly folded to enlarge the surface and forms the so-called cristae. All membrane proteins that are involved in the oxidative phosphorylation are located at the inner membrane. These proteins pump protons into the intermembrane space driven by an electron transfer.
Then, what is the name of the inner membrane of the mitochondria that are made into numerous folds?
cristae
Why is the inner membrane of mitochondria ruffled?
*The inner layer of mitochondria is ruffled because of more surface area. *Mitochondria might have originated from symbiotic bacteria because they took up residence inside the first eukaryotic cells. Desribe the arrangment of mocrotubles that compose the centrioles.

What is the main function of mitochondria of the cell?
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).Why do liver cells have lots of mitochondria?
For example, liver cells and muscle cells contain a lot of mitochondria. Muscle cells are assiciated with a large number of mitochondria as they require more ATP (energy) to function than other cells. They need this because of their frequent contraction and relaxation, which requires more ATP than average cells.Does the mitochondria have a nucleus?
They have no nucleus; instead their genetic material is free-floating within the cell. They also lack the many membrane-bound organelles found in eukaryotic cells. Thus, prokaryotes have no mitochondria.Why is the inner membrane of the mitochondria highly folded quizlet?
Why is the inner mitochondrial membrane folded? Because the cristae increase the surface area for chemical reactions.Why are mitochondria known as powerhouse of the cell?
Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the powerhouses of the cell.Why mitochondria are able to make some of their proteins?
Mitochondria can make some of the protein because they possess ribosomes as well as genetic instructions for manufacturing proteins. This code is found in the mitochondrial DNA together with other important components.How can mitochondria make their own protein?
Mitochondria are capable of making their own protein because it contains ribosomes which helps in making its own protein. Ribosomes are the sites of protein synthesis . Ribosomes are also known as protein factories.What separates the inner and outer membranes of mitochondria?
Mitochondria posses their own DNA and ribosomes. 6. Just like the chloroplast, the stroma separates the inner and outer membranes of the mito- chondria. ATP synthase pumps, by active transport, hydrogen ions back into the mitochondria matrix.What is the cristae in the mitochondria?
Mitochondrial cristae are the folds within the inner mitochondrial membrane. These folds allow for increased surface area in which chemical reactions, such as the redox reactions, can take place.What major classes of proteins are found in the inner mitochondrial membrane?
IMM-associated proteins- NADH dehydrogenase (ubiquinone)
- Electron-transferring-flavoprotein dehydrogenase.
- Electron-transferring flavoprotein.
- Succinate dehydrogenase.
- Alternative oxidase.
- Cytochrome bc1 complex.
- Cytochrome c.
- Cytochrome c oxidase.
What simple sugar is broken down in the mitochondria?
Glucose
What is the function of mitochondria 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. Oxidation releases energy,a portion of which is used to form ATP. Since mitochondria synthesises energy rich compound ATP it is called powerhouse of cell.Where is mitochondria found?
cytoplasm
