What types of transport require ATP?
Active transport processes, such as sodium-potassium pumps and protein pumps in cells, require ATP to move molecules across cell membranes against their concentration gradient. Muscle contraction also relies on ATP for movement in muscle cells.
What process changes the shape of transport proteins when a particle binds with it?
The process that changes the shape of transport proteins when a particle binds to it is called conformational change. This change in shape allows the protein to either open a channel for the particle to pass through or undergo a rotational movement to transfer the particle across the membrane.
Is carrier proteins passive transport or active transport?
Carrier proteins can facilitate both passive and active transport across a cell membrane. In passive transport, carrier proteins help molecules move down their concentration gradient without the need for energy input. In active transport, carrier proteins use energy to transport molecules against their concentration gradient.
What are the two general types of transport used by cells to transport materials in and out of the cell?
The two general types of transport used by cells are passive transport, which does not require energy and includes processes like diffusion and osmosis, and active transport, which requires energy and involves processes like protein pumps and vesicle transport.
Does active transport require a hydrostatic pressure gradient between intracelluar and extracellular regions?
Active transport does not require a hydrostatic pressure gradient specifically, as it utilizes energy from ATP to move molecules against their concentration gradient. However, the presence of gradients (such as concentration or electrical) can affect the efficiency of active transport processes.
Differences between primary and secondary active transport?
In primary active transport, the transport protein gets phosphorylated; in secondary active transport, the transport protein is not phosphorylated
Did NaCl require a transport protein?
Did NaCl require a transport protein for diffusion?
What types of transport require ATP?
Active transport processes, such as sodium-potassium pumps and protein pumps in cells, require ATP to move molecules across cell membranes against their concentration gradient. Muscle contraction also relies on ATP for movement in muscle cells.
Does active transport require a membrane?
Yes, active transport requires a membrane because it involves the movement of molecules or ions against their concentration gradient, which requires energy expenditure. This process is facilitated by specific transport proteins embedded within the membrane.
Is a protein channel active transport?
They are two major active transport proteins.
What is a transport protein?
It's either a passive or active transport.
What process changes the shape of transport proteins when a particle binds with it?
The process that changes the shape of transport proteins when a particle binds to it is called conformational change. This change in shape allows the protein to either open a channel for the particle to pass through or undergo a rotational movement to transfer the particle across the membrane.
What kind of transport require energy?
Active Transport
What does active transport require that passive transport doesn't?
Active transport moves substances against the concentration gradient. That means than it takes energy to drive protein pumps to move something across the cell membrane from a low concentration to a higher one.
Through what type of proteins does active transport occur?
Active transport occurs through carrier proteins that pump molecules against their concentration gradient using energy from ATP. These carrier proteins undergo conformational changes to transport molecules across the cell membrane.
Is carrier proteins passive transport or active transport?
Carrier proteins can facilitate both passive and active transport across a cell membrane. In passive transport, carrier proteins help molecules move down their concentration gradient without the need for energy input. In active transport, carrier proteins use energy to transport molecules against their concentration gradient.
Does active transport require transport proteins?
Yes, active transport does require transport proteins. These proteins use energy to move molecules against their concentration gradient, typically from an area of low concentration to high concentration. This process is essential for maintaining cellular homeostasis.
