3 examples of active transport?
In the intestines, cells use active transport to pump nutrients such as glucose and amino acids from the intestinal lumen into the bloodstream. In the kidney, cells actively transport ions and small molecules from the blood into the nephron tubules for excretion in urine. In nerve cells, active transport is used to maintain the concentration gradients of sodium and potassium ions across the cell membrane, essential for nerve signaling.
Does exocytosis require ATP?
Yes, exocytosis does require ATP because it is a form of active transport. Cell change requires energy.
What types of transport require ATP?
The two types of cell trnsport it Passive Transport and Active Transport. Active Transport does require energy to move into and out of the cell. Passive Transport doesn't require energy to move into and out of the cell. Hope I helped!
What two characteristics describe active transport?
Two characteristics that describe active transport are that active transport: -require energy -always maintain effervescence, which is the the state in which molecules move from a lower concentration to a higher one.
When proteins help transport molecules in and out of the cell it is called . passive diffusion facilitated diffusion active transport endocytosis and exocytosis?
The correct term for proteins helping transport molecules in and out of the cell is facilitated diffusion. This process involves the use of specific proteins that aid in the movement of molecules across the cell membrane, but it does not require energy input from the cell.
Exocytosis active or passive?
active

What do cells use to take in molecules or other cells?
active transport by endocytosis
What is the movement of materials through a cell membrane?
Movement of substances into and out of cells include passive mechanisms that do not require cellular energy (diffusion, facilitated diffusion, osmosis, and filtration) and active mechanisms that use cellular energy (active transport, endocytosis,and exocytosis).
Does exocytosis require ATP?
Yes, exocytosis does require ATP because it is a form of active transport. Cell change requires energy.
Are osmosis and endocytosis passive transports?
It is an active transport,Transport mechanisms fall into two catagories passive and active. Passive transport mechanisms do not require the cell to do work for the substance to enter or leave the cell. Instead the energy involved comes from the kinetic energy of the molecules in solution. Active transport mechanisms involve the cell to use cellular energy usually in the form of ATP to power special protein pumps to bring material into the cell.Passive transport mechanisms Active Transport mechanismsSimple diffusionOsmosisFacilitated DiffusionSimple protein channelsGated channelsActive transport via protein pumpsBulk flow mechanismsendocytosisphagocytosispinocytosisexocytosisThe passive transport mechanisms and the protein pump mechanisms involve movement of substances as single molecules across the membrane. The "bulk" flow mechanisms endocytosis and exocytosis enable the cell to take in very large packages of molecules...say a food item from the environment. Many books treat these bulk flow mechanisms as separate from active transport for that reason.
Does diffusion use vesicles?
No, diffusion does not use vesicles. Diffusion is a passive process in which molecules move from an area of higher concentration to an area of lower concentration without the use of vesicles. Vesicles are used in active transport processes like endocytosis and exocytosis.
How do you use exocytosis in a sentence?
Endocytosis is an energy using process by which cells absorb molecules by engulfing them. "The process of endocytosis happens within cells. "

How do solutes get in and out of the cell?
Solutes can enter and exit cells through various mechanisms such as passive diffusion, facilitated diffusion, active transport, and endocytosis/exocytosis. Passive diffusion occurs when solutes move across the cell membrane down their concentration gradient. Facilitated diffusion involves the use of transport proteins to help solutes cross the membrane. Active transport requires energy to move solutes against their concentration gradient. Endocytosis and exocytosis involve the cell engulfing or releasing solutes by forming vesicles.
What two characteristics describe active transport?
Two characteristics that describe active transport are that active transport: -require energy -always maintain effervescence, which is the the state in which molecules move from a lower concentration to a higher one.
What processes use energy to release substance in or out of the cell?
Active transport processes, such as the sodium-potassium pump or the proton pump, use energy to move substances against their concentration gradients across the cell membrane. Endocytosis and exocytosis also require energy to transport large molecules or particles into or out of the cell, respectively.
