The ribosomes in mitochondria have the same functions as ribosomes elsewhere.
Mitochondria contain DNA in the form of circular molecules. Along this DNA there are 37 genes, of which 13 hold the code for polypeptide chains that contribute to the synthesis of proteins in the inner membrane of the mitochondrion, which is the part of the mitochondrion at which ATP is synthesized.
These 13 genes are transcribed just as nuclear genes are in eukaryotic cells, and the messenger RNA (mRNA) molecules are translated at mitochondrial ribosomes.
The ribosomes are smaller than either prokaryotic or eukaryotic ones, having a sedimentation rate of 55S (Svedberg units) as against 70S for prokaryotic ribosomes and 80S for eukaryotic ones.
What else can I help you with?
What cell that scattered throughout the cell?
Organelles, such as ribosomes and mitochondria, are cells that are scattered throughout the cell. These structures perform specific functions crucial for the cell's survival and overall function.
What type of cell has enzymes DNA ribosomes and mitochondria?
The type of cell that has enzymes, DNA, ribosomes, and mitochondria is a eukaryotic cell. Eukaryotic cells have a defined nucleus that houses DNA, along with various organelles like ribosomes and mitochondria, which are responsible for different cellular functions such as protein synthesis and energy production.
Do plants and animal cells both have Ribosomes and mitochondria?
Yes, both plant and animal cells have ribosomes and mitochondria. Ribosomes are responsible for protein synthesis, while mitochondria are involved in producing energy in the form of ATP through cellular respiration. These organelles are essential for the functioning and survival of both plant and animal cells.
Which organelles are more numerous in active cells?
If a cell is very active, it would need to have a large number of Mitochondria.
Mitochondria contain their own so they can produce their own proteins?
Mitochondria contain their own DNA and ribosomes so they can produce some of their own proteins, particularly those essential for their function in generating energy through cellular respiration. This allows mitochondria to regulate their own processes independently of the cell's nuclear DNA.
Is the mitochondria studded with ribosomes?
Yes, mitochondria have their own ribosomes. These ribosomes are responsible for producing some of the proteins needed by the mitochondria to generate energy through a process called oxidative phosphorylation.
What types are the mitochondria and ribosomes?
Mitochondria have 70s ribosomes.Eukariyotes have 80s ribosomes.
Which is bigger a ribosome or a mitochondria?
Mitochondria are bigger than ribosomes. Ribosomes can be found in mitochondria
Which cell has ribosomes and mitochondria?
Ribosomes are in every cell. Mitochondria are in eukariyotes only
Are there 705 ribosomes in mitochondria?
That is not 705 ribosomes.They have 70s ribosomes.
What are the functions of ribosomes and mitochondria?
Ribosomes are responsible for protein synthesis in the cell, translating mRNA into proteins. Mitochondria are the powerhouse of the cell, generating energy in the form of ATP through the process of cellular respiration.
WHAT PARTOF THE CELL MAKES PROTEINS RIBOSOMES MITOCHONDRIA LYSOSOMES?
Proteins are made on ribosomes. They provide surface for it
What cell that scattered throughout the cell?
Organelles, such as ribosomes and mitochondria, are cells that are scattered throughout the cell. These structures perform specific functions crucial for the cell's survival and overall function.
What type of cell has enzymes DNA ribosomes and mitochondria?
The type of cell that has enzymes, DNA, ribosomes, and mitochondria is a eukaryotic cell. Eukaryotic cells have a defined nucleus that houses DNA, along with various organelles like ribosomes and mitochondria, which are responsible for different cellular functions such as protein synthesis and energy production.
What organelles do plants and animal cells have in common and what is their functions?
Nucleus, ribosomes, mitochondria etc. function for genetic information, protein synthesis and respiration.
Do mitochondria contain functional ribosomes?
Yes they have ribosomes.Mitochondria have 70s ribosomes.
How can mitochondria make their own protein?
Mitochondria have their own DNA and ribosomes, which allow them to synthesize their own proteins independent of the cell's nucleus. The DNA in mitochondria contains genes that encode for proteins involved in energy production and other mitochondrial functions. These proteins are synthesized by mitochondria's ribosomes using the genetic information from their DNA.
