Active transport requires the use of ATP because in active transport things move against the concentration gradient. Usually there is a protien pump (which is a form of a transport protien) that does this.
Transport proteins facilitate the movement of substances across the cell membrane by acting as channels or carriers. Channels allow specific ions or molecules to pass through, while carriers bind to specific molecules and undergo a conformational change to transport them across the membrane. These proteins play a crucial role in maintaining cellular homeostasis by regulating the passage of essential molecules in and out of the cell.
Molecules can cross the cell membrane through simple diffusion, facilitated diffusion via transporter proteins, and active transport using energy to move molecules against their concentration gradient.
Microtubules are made of protein subunits called tubulin. These tubulin subunits polymerize to form long, hollow tubular structures that are essential for various cellular processes such as cell division, cell shape maintenance, and intracellular transport.
Coupled transport is an example of active transport.
Protien also eli is a sexy beast
Transport protiens are open on the outside and the molecule goes in the protien and it flips and then it enters the cell.
Active transport requires the use of ATP because in active transport things move against the concentration gradient. Usually there is a protien pump (which is a form of a transport protien) that does this.
it helps move certain substances such as water and sugar across the membrane.
There is absolutely no protien in a serving of margarine.
Amino acids are the building blocks of protien.
No. It is a protien.
no
protien
Well, chicken is meat and meat is protien, so I guess chicken curry does contain protien. &:)
