Protein pumps, such as the sodium-potassium pump and the proton pump, are membrane structures that function in active transport by moving ions against their concentration gradients across the cell membrane. These pumps require energy, usually in the form of ATP, to transport substances.

where does active transport takes place which part of the cell?
Active transport takes place in the small intestine, where nutrients are absorbed from the intestine and into the bloodstream. More specifically, it is the structures known as villi that contain the protein receptors necessary for active transport to take place. The process also happens in the nephrons of the kidneys, where glucose and water/ions are selectively reabsorbed back into the bloodstream.
What is it called when molecules uses energy to move across a semipermeable membrane?
Active transport
What is it called when sugars pass across the membrane that requires the use of energy?
active transport
What is the principle of active transport?
Active transport is a biological process that requires the input of energy to move substances across a cell membrane against their concentration gradient. This process utilizes specific carrier proteins embedded in the membrane to transport molecules such as ions, sugars, and amino acids. Active transport is essential for maintaining proper cellular function and regulating the internal environment of cells.
What ways of moving molecules across a membrane requires energy?
Active transport requires energy to move molecules across a membrane against their concentration gradient. This process is facilitated by specific carrier proteins embedded in the membrane that use energy, usually in the form of ATP, to transport molecules.
What is the function of active transport moving small molecules and ions across cell membrane?
the movement of materials against a concentration difference is known as active transport. Active transport requires energy.

Active transport
What are the membrane structures that function in active transport?
Membrane structures that function in active transport include ion pumps, such as the sodium-potassium pump, and ATP-powered transporters, such as ABC transporters. These structures use energy to move molecules against their concentration gradient across the cell membrane.
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.
The transport of a substance across the cell membrane against its concentration gradient is called what?
The transport of a substance across the cell membrane against its concentration gradient is called active transport.
Distinguish between active and passive transport?
Active Transport is the passage of materials across the membrane through the expenditure of energy. Passive Transport is the passage of materials across the membrane without the expenditure of energy. Bulk Transport is the type of active transport. Diffusion and Osmosis are type of passive transport.
What is used to move a substance through a membrane in active transport?
Electrochemical gradient is used to move substances through a membrane in active transport.
Which type of membrane transport process uses ATP as a source of energy?
Active transport processes use ATP as a source of energy to move molecules against their concentration gradient across a cell membrane. This process requires specific transport proteins, such as ion pumps, to actively transport molecules across the membrane.

The Na-K pump is an example of active transport?
Yes, that's correct. The sodium-potassium pump actively transports sodium ions out of the cell and potassium ions into the cell against their concentration gradients using energy from ATP. This process helps to maintain the cell's resting membrane potential and is essential for cellular function.
