What is the source of the energy used in active transport?
The energy used in active transport is derived from ATP (adenosine triphosphate), which is produced through cellular respiration in the mitochondria of cells. ATP provides the necessary energy for the transport proteins to move molecules against their concentration gradient across the cell membrane.
How is passive transport different then active transport?
Passive transport does not require energy input and relies on the concentration gradient to move molecules across the cell membrane. Active transport requires energy (usually in the form of ATP) to move molecules against the concentration gradient.
Active transport is the process of what?
Active transport is the process by which a cell uses energy to move molecules or ions across a cell membrane against their concentration gradient. This process requires the use of ATP energy to pump substances from an area of low concentration to an area of high concentration.
Both active transport and facilitated diffusion involve what?
Both active transport and facilitated diffusion involve the movement of molecules across a cell membrane. Active transport requires energy input, usually in the form of ATP, to move molecules against their concentration gradient. In contrast, facilitated diffusion utilizes carrier proteins or channel proteins to move molecules down their concentration gradient without requiring energy input.
What does active transport and facilitated diffusion have in common?
Both active transport and facilitated diffusion are methods of moving substances across cell membranes. Active transport requires energy input to move substances against their concentration gradient, while facilitated diffusion does not require energy and moves substances along their concentration gradient with the help of transport proteins.
active transport reguires?
Active transport requires some form of energy input, usually ATP
What does ATP for the cell?
The ATP makes energy for a cell usually in active transport.
What is the process of active transport a. Exergonic or b. endergonic?
It is b. endergonic because active transport uses ATP for energy.
Is it true that active transport differs from passive transport in that it does not require an input of energy?
No, active transport requires an input of energy, usually in the form of adenosine triphosphate (ATP), to move substances against their concentration gradient. Passive transport, on the other hand, does not require energy and relies on the natural movement of substances down their concentration gradient.
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.
Which type of transport require energy?
Active transport requires energy in the form of ATP
The process of active transport requires the most direct use of?
The process of active transport requires the direct use of cellular energy, usually in the form of adenosine triphosphate (ATP). This energy is needed to move molecules across a cell membrane against their concentration gradient.
Active transport requires energy because it usually involves the movement of what substances?
Molecules
Energy expended by the cell in order for active transport to occur usually comes from a substance known?
The energy for active transport usually comes from the hydrolysis of ATP (adenosine triphosphate), which releases energy that the cell uses to move molecules against their concentration gradient.
How is active transport different from osmosis?
active transport uses energy
How is active transport different from osmosis's?
active transport uses energy
How is facilitated transport different from active transport?
Facilated transport does not need to use energy but active transport does.
