Can mitochondria produce protein?
The short answer: No.
Mitochondria are the power-house of the cell. It is where the Electron Transport Chain takes place as well as the production site almost all of the ATP a cell produces. Proteins are produced by ribosomes of the rough endoplasmic reticulum.
Okay... the answer above is only partially true. Mitochondria do, in fact, synthesize some of their own proteins, due to the fact that they contain their own DNA. However, the first respondent is correct that most of the proteins used in a cell are synthesized in the rough ER. Hope this helps.
Could an organism survive without its mitochondria if all the other organelles were present?
Primordial bacteria have no organelles. They represent the stage of evolution before organelles were acquired. Organelles (probably) began as infectious bacteria invading ameoba-like cells. If the host didn't kill them off and they didn't kill the host then the bacteria become a sort of parasitic organelle. These can be removed without too much harm to the host. In fact the host would probably benefit by their removal. If the parasitic bacteria them started to provide some service to the host cell then the host benefits from their presence. If the service they provide duplicates some basic process of the host then the host will 'forget' how to do the service itself and rely solely on its (now) symbiotic organelles. This is a very common facet of living things: if you don't use a certain ability then you lose it. Removal of the organelles at this stage would be fatal to the host.
How does mitocondra and chloroplast work to gether?
Since the mitochondrial produces Carbon dioxide and water the chloroplast takes those products and makes sugar and oxygen, which those two products are taken by the mitochondrial to produce its products.
This diagram will clarify more:
Chloroplast gives=sugar+oxygen
Sugar+oxygen goes to mitochondrial
Mitochondriall gives= carbon dioxide +water
Carbon + water goes to chloroplast
How does exercise Increased number of mitochondria?
Mitochondria make the energy in your body. During exercise you need more energy so you need more energy "factories"
Which activity occurs in s mitochondria?
Proteins are made
Main activity is respiration.It produces energy through respiration
How many times is chloroplast larger than mitochondria?
This is a relatively complicated question as the exact origins of mitochondria and how they came to be included in eukaryotic cells is still under investigation and therefore open to debate.
Everyone seems to agree though, that they originally come from bacterium and that they were assimilated into eukaryotic cells either because they were useful or through some form of symbiosis.
As mitochondria are common to both plant and animal cells it could therefore be argued that they shared a common ancestor at some point in evolution.
The inclusion of the chloroplast came later, and a separate line of mitochondrial and chloroplast carrying cells evolved - eventually becoming plants. The line without the chloroplast becoming animals.
Can your body produce a natural lubricant?
Astroglide is best natural personal lubricant and is recommended by health professionals and clinics.
ASTROGLIDE Natural Personal Lubricant is free of glycerin, free of alcohol, free of petroleum, free of fragrance, free of flavourings and free of hormones. It is water based, water soluble, latex safe, soft and smooth, long lasting and also a moisturiser.
It lasts longer than any other personal lube and less need be applied. ASTROGLIDE Natural is ALL NATURAL and contains purified water, Aloe Vera, Vitamin C & E and Chamomile (known antibacterial).
It contains:
Aloe Vera - Aloe vera soothes, moisturises and softens skin Chamomile Flower Extracts - Flower-derived chamomile extract offers additional soothing as well as anti-bacterial properties
Vitamins C & E - Vitamins C and E contribute antioxidant benefits
Xylitol - Corn cob-derived xylitol is a natural, sugar-free humectant that helps retain and absorb moisture
It is non sticky, PH balanced, contains no sugar, does not stain clothes or sheets, very slippery and you only need a small quantity, whereas you need heaps with the others. Its available world-wide http://www.astroglide.com/
Which does not take place in the mitochondria of the cell?
Glycolysis. The Krebs cycle and Electron Transport Chain or Oxidative Phosphorylation both occur in the Mitochondria. For photosynthesis, the process takes place in the chloroplasts which are in the mesophyll cells of the leaves. Don't know if this answer is going to help. And because of this i think i m going to have to do my ap bio hw tomoro. thanks a lot.
What is the formula that shows the release of energy by the mitochondria?
Mitochondria are significant to a cell because they are the site of aerobic cellular respiration. In the cytoplasm, glucose is converted anaerobically into pyruvate. The pyruvate enters the mitochondrion, where a series of reactions called the Krebs cycle breaks it down to carbon dioxide and water. A summary of this pyruvate breakdown is: C3H4O3 → 3CO2+ 3H2O During this process, energy is released as bonds of organic molecules are broken. At some stages, energy is released in large enough packets to drive the synthesis of ATP: ADP + Pi → ATP [Pi= an inorganic phosphate ion] For the individual reactions of the Krebs cycle, visit: http://en.wikipedia.org/wiki/Krebs_cycle
How much ATP can be produced without mitochondria?
Yes, Mitochondria make up to 80% of our atp, without it we cannot survive, but it doesnt mean it is the only source of atp.
What is two types of ribosomes and mitochondria?
The difference between ribosomes of prokaryotes and eukaryotes is the structure of the ribosomes. Prokaryotes have 70S ribosomes, each consisting of a small (30S) and a large (50S) subunit. Eukaryotes have 80S ribosomes, each consisting of a small (40S) and large (60S) subunit.
In eukaryotes, the ribosomes may be classified as either 'free' or 'bound'. Free ribosomes may be found suspended in the cytosol whereas bound ribosomes are attached to endoplasmic reticulum (as such called rough endoplasmic reticulum).
Where are large numbers of mitochondria found in?
Large numbers of mitochondria are typically found in cells that have high energy demands, such as muscle cells, liver cells, and cells of the heart. These organs and tissues require significant energy production to carry out their functions effectively.
Why does the mitochondria have folds?
Generating ATP is efficient whe surface area is high.Inner folds increase the surface area.
What is the function of mito chondrion?
The purpose of mitochondria in a cell is to basically convert food into energy. Imagine it as the powerhouse of a cell.
Mitochondria gets energy from glucose through what process of?
Mitochondria gets energy from glucose through the process of Cellular Respiration.The process by which ATP is manufactured from glucose is called cellular respiration.
What do mitochondria do in liver cells?
Mitochondria in liver cells are responsible for generating energy through a process called oxidative phosphorylation. They help produce ATP, which is the main source of energy for cellular functions in the liver. Mitochondria also play a role in the metabolism of fatty acids and detoxification processes in liver cells.
The rate of aerobic respiration in the mitochondria is dependent on the surface area of the cristae because energy potential is built up through the pumping of hydrogen ions across the membrane. With more membrane surface area, there is more energy production and storage capacity so the rate of aerobic respiration may increase.
What chemical reaction that occurs during mitochondria?
I think you are asking about the respiration reaction
Glucose + oxygen ---> carbon dioxide + water
C6H1206 + 6 O2 ---> 6 CO2 + 6 H2O (balanced equation)
What in the mitochondria break down food molecules?
Mitochondria use glucose as fuel.So food we eat converted to glucose.
How are mitochondria and chloroplast linked?
Chloroplasts and mitochondria both create ATP. Chloroplasts use sunlight, glucose, and carbon dioxide to create ATP, and the process also creates oxygen. Mitochondria use oxygen and glucose to create ATP, and the process creates carbon dioxide. Plant cells contain both chloroplasts and mitochondria, but animal cells contain only mitochondria.
Are mitochondria and bacteria the same size?
0.5 micrometers = 0.0005 millimeters Bacteria Escherichia coli cells, an "average" sized bacterium, are about 2 micrometres (μm) long and 0.5 μm in diameter, Mitochondrion (plural mitochondria) Mitochondrion=0.5-10 micrometers (μm) in diameter.
