How do mitochondria differ from ribosomes? | Socratic
Relationship Between Cell Structure & Function. By Contributor Ribosomes are puny pieces of protein found all over the cell. Mitochondria. Structure and function of mitochondria and chloroplasts. Why would these organelles need DNA and ribosomes, when there is DNA in the nucleus and scientists think host cells and bacteria formed endosymbiotic relationships long ago. Mitochondria is a completely different Organelle than the Ribosomes. adopted most multicelled animals billions of years ago for the symbiotic relationship. the cell for other works to do works (for function) ATP is energy rich molecule made.
Mitochondria and chloroplasts
Like messages, instructions and blueprints moving in and out of a main office, a river of proteins go through the nuclear pores to and from the rest of the cell.
Ribosomes Creating proteins is one of the most crucial jobs in a cell. They are made on ribosomes.
Ribosomes are puny pieces of protein found all over the cell. Each ribosome, in its own way, is like a small machine in a factory, spiraling out proteins on instructions that arrive from its nucleus. The endoplasmic reticulum is the site where the apparatus of the membrane are assembled, along with proteins and other materials that are exported from the cell.
The rough ER is given this name because of the ribosomes found on its surface. Newly made proteins leave these ribosomes and are put in the rough endoplasmic reticulum, where they will be modified chemically.
Golgi Apparatus Proteins made in the rough ER move next into an organelle called the Golgi apparatus. This organelle was discovered by the Italian scientist Camillo Golgi.From DNA to protein - 3D
In the Golgi apparatus, proteins are put all over the cell Lysosomes Even the neatest, cleanest factory needs a cleanup crew, and that's what lysosomes LY-suh-sohmz are. Lysosomes are small organelles filled with enzymes.
One function of lysosomes is the digestion of lipids into molecules that can be used by the rest of the cell.
Lysosomes are also involved in breaking down organelles that have outlived their usefulness. A number of serious human diseases can be traced to lysosomes. Vacuoles Every factory needs a place to store things, and cells contain places for storage as well. Some cells have compositions called vacuoles VAK-yoo-ohlz that stock up resources such as proteins and salts.
what is the relationship between mitochondria and ribosomes? | Yahoo Answers
BiologyWise Staff Last Updated: Mar 19, While studying the plant and animal cell, you might have come across many organelles that coordinate together to carry out the cell activities. One such important cell organelle is the ribosome, which is responsible for protein synthesis.
While mitochondria are considered as powerhouse of the cell for energy production, ribosomes are popularly related as the site for protein synthesis in a cell. Ribosomes Composition and Structure Ribosomes are composed of ribonucleic acid abbreviated as RNA and proteins, in nearly equal amounts. The ribonucleic acid is derived from the nucleolus, where ribosomes are synthesized in a cell. A simple prokaryotic cell for example, bacteria consists of a few thousands of ribosomes, whereas a highly developed eukaryotic cell for example, human cell has a few millions of ribosomes.
Prokaryotic ribosomes are smaller in size as compared to the eukaryotic ones. Coming to the ribosomal structure, a typical ribosome consists of two subunits, each of which contains RNA and proteins.
These two subunits are categorized with respect to the rate of sedimentation in a specific medium.

For example, the two subunits in a eukaryotic cell are 40S smaller subunit and 60S larger subunitwhere 'S' stands for the density unit, Svedberg. Thus, the higher the value assigned to the subunit, the larger is the size of the subunit.
