Which organelle packages protein in vesicles and sends them the body where they are needed?
Golgi apparatus
What requires vesicles for transportation across cell membrane?
It is a type of active transportation.So energy is needed.
How are the small sacks that seal substances from the Golgi apparatus made?
They are 'pinched off' somewhat like a doing that with very soft clay. These are now called vesicles. And these vesicles are pulled off the membranes and travel to where they are needed.
What is the advantage for melanin granules being located in the deep layer of the epidermis?
The melanin is used to protect the cell's nucleus from the UV radiation from the sun. Since the upper layers of the skin are dead, there either is no nucleus remaining, or there simply is no need to protect the nucleus, therefore melanin granules are needed only in the deeper layers of skin
What does the Golgi apperatis do in a cell?
Receives modified proteins from the ER, further modifies them, packages them in vesicles and ships them to places in the cell where they are needed and to places where needed outside the cell. Lysosome synthesis here also.
Why might some people say Article 7 of the Constitution is no longer needed?
Why are some people say that Article BIO is no longer needed
What is needed to move a vesicle along micro tubules toward the center of the cell?
Mitotic spindles are needed to move the micro tubules to the center of the cell. Added: Motor proteins generally move vesicles around the cell.
Why do vesicles move around the cytoplasm?
Vesicles move around the cytoplasm so they can get needed nutrients around the cell so the cell can survive. The vesicles do this two ways, they can either be carted by special proteins called Dyein and Kinesin along the cytoskeleton, or they build up a substance called actin to a certain pressure then use it to jet around the cell.
What does the golgi produce?
The Golgi body modifies and ships proteins in vesicles to other parts of the cell where needed and out of the cell if need be. Also the Golgi is the site of lysosome synthesis.
Why was napoleon willing to sell the Louisiana territory to the united states?
He no longer needed a base in North America. (apex)
Why do Africans have large noses and kinky hair?
Climactic adaptations. The continent of Africa was the cradle of humanity. As people migrated to colder climates, noses narrowed because the air was colder.Breathing in large amounts of cold air causes bronchial spasms. Hair became straighter and longer to protect ears and neck from the cold.Same with skin color. People closer to the Equator needed more melanin to protect them from the sun. Scandinavian peoples have less intense sun, and long , dark winter days, so don't need as much melanin.
Why is the energy expended during endocytosis worth it?
Endocytosis is the bulk transport of materials into a cell, using energy in the form of ATP. It is an active process, and the energy is used to move the membranes around the materials to form the vesicles that are needed, and to move the vesicles into the cell.
