What occurs when substances move against the concentration gradient requires and the aid of carrier proteins?

Carrier molecules are molecules that play a role in transporting electrons through the electron transport chain. Carrier molecules are usually proteins bound to a nonprotein group; they can undergo oxidation and reduction relatively easily, thus allowing electrons to flow through the system. There are four types of carrier: flavoproteins (e.g. FAD), cytochromes, iron-sulphur proteins (e.g. ferredoxin), and ubiquinone.

What is the process that requires cellular energy to move a substance against its concentration gradient?
Active transport uses energy to move substances against the concentration gradient.
What is the movement of chemical substances usually across the cell membrane againts a concentration gradient requires cells to energy?
active transport
What movement of the substances through a cell membrane against a concentration gradient requires energy?
no because it is a form of passive transport. only active transport requires energy. facilitated diffusion just means that it cant be just absorbed through the membrane, it must go through specific chanels or be helped by transport proteins. but because facilitated diffusion moves from higher to lower concentrations, it requires no energy.
Proceeds Against a concentration Gradient requires a carrier?
Solute pump
What is the type of transport in which a cell goes against the concentration gradient in order to diffuse substances within?
Active transport is used to move molecules and ions across a membrane against their concentration gradient. "Active" means that the transporter requires energy to do its job (eg. glucose).
What is the process that requires cellular energy to move a substance against its concentration gradient?
Active transport uses energy to move substances against the concentration gradient.
Do Substances naturally diffuse up a concentration?
no down a concentration gradient high to low if its low to high it requires energy
Does active transport require transport proteins?
Yes, active transport requires carrier proteins in order to function. These require ATP to carry things in and out of the cell.
Active transport requires what?
Energy-requiring process by which substances move across the plasma membrane against a concentration gradient.
What is difference between active and passive?
Active transport requires an input of energy and can move substabces against their concentration gradient. Passive transport does not require added energy and can move substances only down their concentration gradient.
What is the movement of chemical substances usually across the cell membrane againts a concentration gradient requires cells to energy?
active transport
What movement of the substances through a cell membrane against a concentration gradient requires energy?
no because it is a form of passive transport. only active transport requires energy. facilitated diffusion just means that it cant be just absorbed through the membrane, it must go through specific chanels or be helped by transport proteins. but because facilitated diffusion moves from higher to lower concentrations, it requires no energy.
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.
What is endocytosis's concentration gradient?
Yes - as endocytosis requires energy.
What is the difference between active and passive diffusion?
passive diffusion requires absolutely nothing, no energy either, the particles simply flow from a high concentration gradient to a low concentration gradient. Active transport however require carrier proteins to allow the particles through the cell membrane
Proceeds Against a concentration Gradient requires a carrier?
Solute pump
How is facilitated diffusion different than normal diffusion?
Diffusion is the movement of molecules or partocles from an area of high concentration to an area of lower concentration, and Facilitated diffusion is when substances difuse across cell membranes more rapidly than you might expect.
