Melanin vesicles, or melanosomes, are destroyed through a process called autophagy, where cellular components are degraded and recycled. When melanin production is no longer required, cells recognize the excess melanosomes and target them for elimination. Lysosomes, which contain enzymes that break down cellular debris, play a key role in this degradation process. This ensures that cellular homeostasis is maintained and prevents the accumulation of unnecessary melanin.
What else can I help you with?
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 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.
What effect would surgical removal of the seminal vesicles have on the human male reproductive system?
Surgical removal of the seminal vesicles can lead to a decrease in semen volume and fertility because the seminal vesicles produce a significant portion of the fluid in semen. However, it may not affect the ability to have erections or ejaculation. Hormonal changes or treatments may be needed to manage related symptoms.
Why was napoleon willing to sell the Louisiana territory to the united states?
He no longer needed a base in North America. (apex)
How does the Golgi transport lipids?
The Golgi transports lipids by receiving them from the endoplasmic reticulum in vesicles, modifying them as needed, and then packaging them into new vesicles for transport to their final destination within the cell or outside of the cell. The Golgi apparatus also plays a role in sorting and directing the lipids to different cellular compartments.
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.
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 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.
