Active transport requires energy because it typically involves the movement of molecules against their concentration gradient, meaning substances are moved from an area of lower concentration to an area of higher concentration. This process is essential for maintaining cellular homeostasis and enabling cells to uptake necessary nutrients or expel waste products. The energy for this transport often comes from ATP, which powers the transport proteins or pumps involved.
What else can I help you with?
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 symport is active transport or passive transport?
Symport is a form of active transport. It involves the movement of two or more substances across a cell membrane in the same direction, using energy typically derived from the electrochemical gradient of one of the substances. This process requires energy input because it often moves substances against their concentration gradients.
What movement against a concentration gradient from low to high concentration?
The movement against a concentration gradient from low to high concentration is known as active transport. This process requires energy, usually in the form of ATP, because it involves the movement of substances against their natural tendency to flow from areas of higher concentration to areas of lower concentration. Active transport is essential for maintaining cellular functions, such as nutrient uptake and ion regulation. Examples include the sodium-potassium pump and the transport of glucose into cells.
Is water an active or passive transport?
Water can use both passive and active transport mechanisms. Passive transport involves movement of water molecules across a membrane without the need for energy, while active transport involves the use of energy to move water molecules against their concentration gradient.
Is pushing a cart through a store more like active transport or passive transport Why?
Pushing a cart through a store is more like active transport because it requires energy and effort to move the cart against resistance, such as friction or gravity. Active transport involves moving substances across a membrane against a concentration gradient, which also requires energy. In contrast, passive transport occurs naturally without energy input, like a ball rolling downhill. Therefore, the act of pushing a cart involves an active process similar to active transport.
Active transport requires energy because it usually involves the movement of what substances?
Molecules

This process requires energy input because it often moves substances against their concentration gradients.
Is osmosis a type of passive transport?
because it involves the movement of molecumes from a point of higher concentration to a lower concentration through a semipearmable membrane..
What movement against a concentration gradient from low to high concentration?
The movement against a concentration gradient from low to high concentration is known as active transport.

Active transport is essential for maintaining cellular functions, such as nutrient uptake and ion regulation. Examples include the sodium-potassium pump and the transport of glucose into cells.
Why does active transport require more energy than osmosis or facilitated diffusion?
Active transport requires more energy than diffusion this is because during active transport, the molecules are being transported against and toward the concentration gradient whereas in diffusion, the molecules go from the concentration gradient.
Does active transport require a transport protein?
Active transport requires the use of ATP because in active transport things move against the concentration gradient. Usually there is a protien pump (which is a form of a transport protien) that does this.
Is facilitated diffusion reversible?
Yes, facilitated diffusion is reversible because it involves the movement of molecules across a membrane with the help of transport proteins. These transport proteins can facilitate the movement of molecules in both directions depending on the concentration gradient of the specific molecule.
Why transport proteins require energy to function in active transport?
Because there is a higher concentration inside the cell then out side ....because it requires energy to move the molecules outside in a different direction then they would normally move, it is like riding a bike up a hill it requires energy.
Which type of transport require energy?
Active transport requires energy in the form of ATP
