Yes primary active transport machinery (protein pumps) relies on phosphorylation of the carrier protein. ATP hydrolysis yields the phosphate molecule to interact with the protein pump. This cause the conformational change in the ion channel protein to carry out exchange of ions. For example: sodium-potassium pump: binding of phosphate release sodium from cell, whereas dephosphorylation allows the entry of potassium ions inside the cell.
What else can I help you with?
Does active transport involve the movement of molecules against the concentration gradient?
Yes, active transport involves the movement of molecules against the concentration gradient.
Does osmosis involve transport proteins?
No, osmosis does not involve transport proteins. Osmosis is the passive movement of water across a selectively permeable membrane in response to a concentration gradient. Transport proteins are involved in facilitated diffusion and active transport processes.
In what ways are active transport and facilitated diffusion similar?
Active transport and facilitated diffusion are similar in that they both involve the movement of molecules across a cell membrane, but they differ in that active transport requires energy input from the cell, while facilitated diffusion does not.
Materials can be moved from a low concentration to a high concentration through?
active transport processes like primary active transport or secondary active transport, which require energy to move molecules against their concentration gradient. This can involve the use of transport proteins or ion pumps in the cell membrane.
Is coupled transport an example of active or passive transport?
Coupled transport is an example of active transport.
Does active transport involve the movement of molecules against the concentration gradient?
Yes, active transport involves the movement of molecules against the concentration gradient.

What are the similarities between facillitated transport and active transport?
Both facilitated transport and active transport involve the movement of molecules across a cell membrane with the help of carrier proteins. However, facilitated transport does not require energy input from the cell, while active transport does require energy in the form of ATP. Both processes are specific and selective in what molecules they transport across the membrane.
What is a good sentence for Active Transport?
Active Transport is carried out in our body cells. Active Transport uses energy to transport materials.
Does Transcytosis combine diffusion and active transport?
Transcytosis is a cellular process that involves the transport of molecules across a cell via vesicles. It combines aspects of both endocytosis (a form of active transport) and exocytosis, allowing substances to move from one side of the cell to the other. While the vesicle transport requires energy (active transport), the actual movement of molecules within the vesicles can also involve diffusion. Thus, transcytosis incorporates both active transport and diffusion in its mechanism.
Is testosterone a passive transport or an active transport?
it is an ACTIVE transport.
Is an active transport active or passive?
It has is in the name. Active Transport
Both active transport and facilitated diffusion involve what?
Both active transport and facilitated diffusion involve the movement of molecules across a cell membrane. Active transport requires energy input, usually in the form of ATP, to move molecules against their concentration gradient. In contrast, facilitated diffusion utilizes carrier proteins or channel proteins to move molecules down their concentration gradient without requiring energy input.
IS Active transportation a carrier of protein?
Active transport is not a carrier of protein; rather, it is a cellular process that moves molecules across a membrane against their concentration gradient, often requiring energy in the form of ATP. This process can involve transport proteins, such as pumps and carriers, that facilitate the movement of ions and small molecules. While proteins themselves can be involved in active transport, the term "active transport" refers specifically to the mechanism rather than the transport of proteins.
What is it called when molecules uses energy to move across a semipermeable membrane?
Active transport
