Cells use energy in the form of adenosine triphosphate (ATP) to perform active transport. This energy is required to move substances against their concentration gradient, from areas of lower concentration to areas of higher concentration. Active transport allows cells to maintain internal conditions and regulate the movement of molecules.

What are two ways in which cells use the energy provited by ATP?
Cells use the energy from ATP for active transport and protein synthesis.
What is the process that requires the use of energy to move materials across a membrane?
Active transport is the process that requires the use of energy to move materials across a membrane. This process involves the movement of molecules against their concentration gradient, requiring energy input from the cell.
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.
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 are 2 situations which active transport would be required?
Active transport is required in situations where molecules need to move against their concentration gradient, such as in the absorption of nutrients in the intestines or the reabsorption of ions in the kidney tubules. Additionally, active transport is necessary for the maintenance of electrochemical gradients, like the pumping of sodium and potassium ions by the sodium-potassium pump in nerve cells.
To perform active transport cells use what?
Energy, versus passive in which energy is not used.
What perform active transport cells use?
Energy, versus passive in which energy is not used.
What do cells use to take in molecules or other cells?
active transport by endocytosis
To perform active transport cells use?
In active transport, cells use energy (usually from ATP) to move molecules against their concentration gradient across a cell membrane. This process allows cells to accumulate molecules or ions inside the cell or expel them outside, maintaining the cell's internal environment and enabling various cellular functions. Examples of active transport mechanisms include the sodium-potassium pump and the hydrogen-potassium pump.
What do Cells use to make active transport?
Proteins and Atp energy.
What do cells use to transport substances reproduce and perform chemical reactions?
A fluid
How do you use active transport in a sentence?
Cells use active transport to pump nutrients into the cell against their concentration gradient.
What cells use active transport?
Energy, versus passive in which energy is not used.
How might life be different if cells had to use active transport to move every substance?
Life would be very difficult and processes would drag if cells were to use active transport to move every substance to its destination.
What are the two ways which cells use the energy provided by ATP?
Cells use the energy from ATP for active transport and cell division.
What are two ways which the cells use the energy provided by ATP?
Cells use the energy from ATP for active transport and cell division.
What are two ways in which cells use the energy provited by ATP?
Cells use the energy from ATP for active transport and protein synthesis.
