ViviProtein 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.

What is it called when molecules uses energy to move across a semipermeable membrane?
Active transport
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 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.
