What are the two types of transport across the cell membrane?
active transport and passive transport. active transport requires energy and able to transport molecules from low concentration side to higher concentration side. passive is just like a tube that connects innner side and outer side. it requires no energy but unable to do like active transport does
What is the function of the Golgi vesicles?
The Golgi apparatus is able to: 1. Glycosylate (add sugar goups) to proteins 2. Enclose proteins vesicles and transport to a region of the cell where they are requird to perform a specific function
If a cell lacked ribosomes it wouldn't be able to do what?
It wouldn't be able to synthesize proteins.
Does osmosis require membrane proteins?
No, osmosis is a special type of diffusion in which a water molecule is able to passively transport through a membrane without a protein. Although it is polar, it's extremely small size makes this possible
What requires a host cell because they are not able to make proteins on their own?
Viruses.
Why do cells need carriers proteins that transport glucose?
Large molecules, such as glucose, are not able to pass through the cell membrane. Therefore proteins are needed to transport them across.
Which type of proteins are involved in nutrient transport and why?
integral proteins, because they span the membrane and thereby are able to carry nutrients across the membrane
What are the two types of transport across the cell membrane?
active transport and passive transport. active transport requires energy and able to transport molecules from low concentration side to higher concentration side. passive is just like a tube that connects innner side and outer side. it requires no energy but unable to do like active transport does
What do transport dos?
Transport proteins help move (or "transport") large molecules that aren't able to pass through a cell's membrane, through said cell membrane through means of diffusion.
How does the nucleus control the functions of life?
it controls all the activities of the cells and the cells transport proteins and you need proteins to be able to digest food, see, and move around.
How do transport proteins work?
They are used in Facilitated Diffusion, helping to transport ions, macromolecules, and other substances incapable of entering a cell by themselves to cross through the plasma membrane of the cell.
Why does the endoplasmic reticulum have so many tubes?
It has so many tubes because it must be able to transport proteins and other materials throughout the entire cell.
Why mitochondria are able to make some of their proteins?
as they contain their own DNA and hence are able to synthesize proteins,but the DNA contains small number of genes so it is able to produce some of the proteins.
What is the function of the Golgi vesicles?
The Golgi apparatus is able to: 1. Glycosylate (add sugar goups) to proteins 2. Enclose proteins vesicles and transport to a region of the cell where they are requird to perform a specific function
What would happen if the cell didn't contain the smooth ER?
The cell would be unable to transport vital materials, such as proteins, to other parts of the cell. The cell wouldn't be able to function and it would die.
How is the Proteins that are secreted from a eukaryotic cell must first travel through the endomembrane system set up?
As they are being synthesized, secretory proteins enter the lumen of the endoplasmic reticulum. From the ER, vesicles transport these proteins to the Golgi, where they are sequentially modified and concentrated in a cis-to-trans direction. Secretory vesicles bud from the Golgi and move along cytoskeletal filaments to eventually fuse with the plasma membrane, secreting their protein cargo. Each of these transport steps requires specialized proteins to ensure that the cargo is sent to the proper location and is able to fuse with the target membrane.
If a cell lacked ribosomes it wouldn't be able to do what?
It wouldn't be able to synthesize proteins.
