What are ribosomes main function?
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 are examples of mitochondria?
“What do you mean, example? Mitochondria are the cell organelles where respiration takes place.” “Your junk food unit is usually an demonstration of mitochondria since it gives you power and fire, just as the mtochondria reduces foodstuff substances to discharge electricity.
What is the other name of mitochondria?
power house of cellMitochondria is also known as power house of cell due to the production of ATP or kreb’s cycle and ETS taking place in it. Other name of mitochondria is POWER HOUSE OF CELL. A common name is the ‘powerhouse of the cell’.
What is the structure of mitochondria explain with diagram?
Structure of Mitochondria The mitochondrion is a double-membraned, rod-shaped structure found in both plant and animal cell. Its size ranges from 0.5 to 1.0 micrometre in diameter. The structure comprises an outer membrane, an inner membrane, and a gel-like material called the matrix.
What is Golgi apparatus Class 9?
Golgi apparatus. Golgi apparatus. The stacks of flattened membranous vesicles are called Golgi apparatus. It basically stores, packs and modifies the products in vesicles. It temporarily stores protein that moves out of the cell through the vesicles of the Golgi apparatus.
How do mitochondria die?
Without oxygen, the mitochondria stop working, and the cells in the brain or heart are damaged or even die. Perversely, if the oxygen does return, then the mitochondria get overwhelmed and produce a lot of “free radicals”.
What are the two main function of ribosomes?
A ribosome is a cell organelle. It functions as a micro-machine for making proteins. Ribosomes are composed of special proteins and nucleic acids. The TRANSLATION of information and the Linking of AMINO ACIDS are at the heart of the protein production process.
What organ has the most mitochondria?
heart muscle cellsA. Your heart muscle cells – with about 5,000 mitochondria per cell. These cells need more energy, so they contain more mitochondria than any other organ in the body!
What are the two functions of mitochondria?
Known as the “powerhouses of the cell,” mitochondria produce the energy necessary for the cell’s survival and functioning. Through a series of chemical reactions, mitochondria break down glucose into an energy molecule known as adenosine triphosphate (ATP), which is used to fuel various other cellular processes.
How are mitochondria formed?
Mitochondria and chloroplasts likely evolved from engulfed prokaryotes that once lived as independent organisms. At some point, a eukaryotic cell engulfed an aerobic prokaryote, which then formed an endosymbiotic relationship with the host eukaryote, gradually developing into a mitochondrion.
What is mitochondria in biology?
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions. … Generally, mitochondria, and therefore mitochondrial DNA, are inherited only from the mother.
What are ribosomes Class 9?
“Ribosomes are most important cell organelles composed of RNA and protein that converts genetic code into chains of amino acids.”
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.
Where is mitochondria found?
cytoplasmMitochondria are found in all body cells, with the exception of a few. There are usually multiple mitochondria found in one cell, depending upon the function of that type of cell. Mitochondria are located in the cytoplasm of cells along with other organelles of the cell.
What is the main function of ribosomes Class 9?
Ribosomes are a cell structure that makes protein. Protein is needed for many cell functions such as repairing damage or directing chemical processes. Ribosomes can be found floating within the cytoplasm or attached to the endoplasmic reticulum.
What is the function of mitochondria class 9th?
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.
What is mitochondria in simple words?
Mitochondria (sing. mitochondrion) are organelles, or parts of a eukaryote cell. They are in the cytoplasm, not the nucleus. They make most of the cell’s supply of adenosine triphosphate (ATP), a molecule that cells use as a source of energy. … They oxidise glucose to provide energy for the cell.
What is a mitochondria made of?
A mitochondrion contains outer and inner membranes composed of phospholipid bilayers and proteins.
