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

How do mitochondria make ATP?

Most of the adenosine triphosphate (ATP) synthesized during glucose metabolism is produced in the mitochondria through oxidative phosphorylation. This is a complex reaction powered by the proton gradient across the mitochondrial inner membrane, which is generated by mitochondrial respiration.

What is the inner membrane of mitochondria made of?

The mitochondrial inner membrane is made primarily of a phospholipid bilayer, just like the cell membrane. Embedded in this bilayer are various proteins that serve to carry out the electron transport chain. The membrane has folds called christae that increase its surface area.

What does the intermembrane space do in the mitochondria?

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. The matrix contains the enzymes that are responsible for the citric acid cycle reactions.

What proteins are found in the mitochondria?

The mitochondrial inner membrane carries two large ATP-dependent protease complexes, the iAAA protease and the matrix-exposed mAAA protease^{18,161,162,163}. These proteases are main elements of a quality control system for protein processing and turnover in mitochondria.

What are the sites of protein synthesis?

Ribosomes are the sites in a cell in which protein synthesis takes place. Cells have many ribosomes, and the exact number depends on how active a particular cell is in synthesizing proteins. For example, rapidly growing cells usually have a large number of ribosomes (Figure 5).

Which organelle is used for storage?

Cells that use a lot of energy may have thousands of mitochondria. Vesicles are small membrane bound sacs that transport materials around the cell and to the cell membrane. The vacuoles are like storage centers. Plant cells have larger vacuoles than animal cells.

What produces ribosomes in the cell?

Eukaryote ribosomes are produced and assembled in the nucleolus. Ribosomal proteins enter the nucleolus and combine with the four rRNA strands to create the two ribosomal subunits (one small and one large) that will make up the completed ribosome (see Figure 1).

What is the main function of ribosome?

Ribosomes have two main functions — decoding the message and the formation of peptide bonds. These two activities reside in two large ribonucleoprotein particles (RNPs) of unequal size, the ribosomal subunits. Each subunit is made of one or more ribosomal RNAs (rRNAs) and many ribosomal proteins (r-proteins).

What is produced in the smooth ER?

The smooth endoplasmic reticulum functions in many metabolic processes. It synthesizes lipids, phospholipids as in plasma membranes, and steroids. Cells that secrete these products, such as cells of the testes, ovaries, and skin oil glands, have an excess of smooth endoplasmic reticulum.

What cell part packages proteins?

The Golgi apparatus modifies, sorts, and packages different substances for secretion out of the cell, or for use within the cell. The Golgi apparatus is found close to the nucleus of the cell where it modifies proteins that have been delivered in transport vesicles from the Rough Endoplasmic Reticulum.

What manufactures proteins in a cell?

Ribosomes are the protein factories of the cell. Composed of two subunits, they can be found floating freely in the cell's cytoplasm or embedded within the endoplasmic reticulum.

What does the Golgi apparatus do?

The Golgi apparatus transports and modifies proteins in eukaryotic cells. How have scientists studied dynamic protein movements through the Golgi? The Golgi apparatus is the central organelle mediating protein and lipid transport within the eukaryotic cell.
