What else can I help you with?
Active transport always requires transport proteins during the process?
false
Does osmosis involve the use of transport proteins?
No, osmosis does not involve the use of transport proteins. Osmosis is the movement of water molecules across a selectively permeable membrane from an area of higher concentration to an area of lower concentration. Transport proteins are not involved in this process.
Which type of transport requires assistance from membrane proteins?
Active transport requires assistance from membrane proteins. These proteins, such as ion pumps and carrier proteins, help move molecules against their concentration gradient, requiring energy input to drive the process.
Does simple diffusion require transport proteins?
No, simple diffusion does not require transport proteins. It is a passive process where molecules move from an area of higher concentration to an area of lower concentration directly through the lipid bilayer of the cell membrane. Transport proteins are involved in facilitated diffusion and active transport.
Food particles move through proteins in the cell membrane without using energy in a process called?
Active transport
How does as large particle leave a cell using active transport?
It requires energy, and a carrier protein. The large particle binds to the carrier protein on the inside of the cell. The protein then changes conformation, thus moving the particle to the outside, where it is dropped off by another conformational change in the protein.
Why can channel proteins mediate much more rapid transport than carrier proteins?
Channel proteins allow ions or molecules to flow freely through a pore, leading to rapid transport without requiring conformational changes. Carrier proteins, in contrast, undergo conformational changes to transport substrates individually, making the process slower than channel proteins.
True or false active transport always requires transport proteins during the process?
true
What can large particle can enter a cell by an active-transport process?
The cell Wall
A larce particle can enter a cell by an active transport process called?
endocytosis
Can proteins pass through transport proteins?
No the soluble proteins can not pass though the transporters on the membrane. Transport proteins are highly specific they only allow the transport of ions such as Na or K across the cell. But transport proteins such as Hemoglobin can carry oxygen or CO2 to all the tissues for respiration.
What macromolecule is involved in facilitated diffusion?
Facilitated diffusion involves the transport of molecules across the cell membrane with the help of transport proteins. These transport proteins are typically made up of proteins, which are macromolecules. Therefore, macromolecules involved in facilitated diffusion are proteins.
Active transport always requires transport proteins during the process?
false
How do transport proteins make make it easier for certain molecules to diffuse across a membrane?
Facilitated diffusion is the diffusion of molecules.across a membrane through transport proteins. Transport proteins make it easier for molecules to enter or exit acell. But the process is still a form of passive transport.
Is the following sentence true or false active transport always requires transport proteins during the process?
false
Is the following sentence true or false active transport always requiring transport proteins during the process?
false
Does osmosis involve the use of transport proteins?
No, osmosis does not involve the use of transport proteins. Osmosis is the movement of water molecules across a selectively permeable membrane from an area of higher concentration to an area of lower concentration. Transport proteins are not involved in this process.
