Why is inner membrane of mitochondria folded and why is it able to make its own protein?
Why is inner membrane of mitochondria folded and why is it able to make its own protein?
Answer Expert Verified (a) inner membrane of mitochondria is folded as it provide more surface area for ATP synthesis.
What is the benefit of folding of inner membrane in mitochondria?
The deeply folded inner membrane of mitochondria provides a large surface area for ATP-generating chemical reactions.
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.
What are the folds of the inner mitochondrial membrane called?
The inner membrane forms invaginations, called cristae, that extend deeply into the matrix. The cristae define the third mitochondrial compartment, the crista lumen. The crista membranes contain most, if not all, of the fully assembled complexes of the electron transport chain and the ATP synthase (Fig.
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.
Why do mitochondria have double membranes?
The double membrane found in mitochondria and chloroplasts appears to be a relic of the absorption of the prokaryotic bacteria by the eukaryotic host cells. The inner membrane, which now contains numerous folds, apparently came from the bacterial membrane, while the outer membrane came from the host cell itself.
What are the two membranes of mitochondria?
As previously mentioned, mitochondria contain two major membranes. The outer mitochondrial membrane fully surrounds the inner membrane, with a small intermembrane space in between. The outer membrane has many protein-based pores that are big enough to allow the passage of ions and molecules as large as a small protein.
Where are mitochondria located?
Mitochondria are structures within cells that convert the energy from food into a form that cells can use. Each cell contains hundreds to thousands of mitochondria, which are located in the fluid that surrounds the nucleus (the cytoplasm).
What is respiration in the mitochondria?
Mitochondrial respiration is the set of metabolic reactions and processes requiring oxygen that takes place in mitochondria to convert the energy stored in macronutrients to adenosine triphosphate (ATP), the universal energy donor in the cell.
What process happens in the mitochondria?
Mitochondria, using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell. The process is called oxidative phosphorylation and it happens inside mitochondria. In ATP the energy is stored in the form of chemical bonds.
What is the cristae in the mitochondria?
The infoldings or inward projections of the inner membrane of the mitochondrion, which are studded with proteins and increase the surface area for chemical reactions to occur like cellular respiration.
Can you tell what shape the mitochondria have?
Mitochondria are typically round to oval in shape and range in size from 0.5 to 10 μm. In addition to producing energy, mitochondria store calcium for cell signaling activities, generate heat, and mediate cell growth and death.
Can you see mitochondria at 400x?
Mitochondria can vary greatly in size. As a result, only the largest mitochondria can be seen with the highest magnification of light microscopes. A light microscope can magnify an image up to 400 times, and the limit of its resolution is about .
Can you see fungi with a light microscope?
To study fungal spores, basidia, cystidia, sphaerocysts and other tiny features of fungi you will need a microscope capable of at least x 400 magnification. Other ‘must-have’ microscope features include: Adjustable illumination, most often from directly below the slide, and termed brightfield illumination.
Can light microscopes see living cells?
Light microscopes are advantageous for viewing living organisms, but since individual cells are generally transparent, their components are not distinguishable unless they are colored with special stains. Staining, however, usually kills the cells.
Is a light microscope 2D or 3d?
Most compound light microscopes produce flat, 2D images because high-magnification microscope lenses have inherently shallow depth of field, rendering most of the image out of focus.
What are the 3 main types of microscopes?
There are three basic types of microscopes: optical, charged particle (electron and ion), and scanning probe.
What is the most powerful type of microscope?
electron microscope
