How is facilitated diffusion different from avtive transport?
Facilitated diffusion is a passive process where molecules move across a membrane with the help of transport proteins, following the concentration gradient and requiring no energy input. Active transport, on the other hand, is an energy-requiring process that moves molecules against their concentration gradient using ATP or an electrochemical gradient.
Moving particles from a place of lower to higher concentration using energy is what process?
The answer is active transports because it goes from high to low concentration h ope this helps.
What process drives molecules across a membrane against a concentration gradient?
Active transport is the process that drives molecules across a membrane against a concentration gradient, requiring energy input in the form of ATP. This process allows cells to accumulate substances they need in higher concentrations than their surroundings.
Which proteins are used in active and passive transport?
In active transport, proteins like pumps (such as Na+/K+ ATPase) are commonly used to move molecules against their concentration gradient, requiring energy in the form of ATP. Passive transport commonly involves proteins like ion channels and carrier proteins that facilitate the movement of molecules down their concentration gradient without requiring energy input.
What is the function of active transport in moving small molecules and ions across cell membranes?
Active transport is a process that moves molecules and ions against their concentration gradient, requiring energy in the form of ATP. This mechanism allows the cell to maintain internal concentrations of molecules that are different from their surroundings, facilitating processes like nutrient uptake and waste removal.
What is The energy-requiring movement of materials against a concentration gradient?
Active absorption
Does passive transport move substances against the concentration gradient?
No, passive transport does not move substances against the concentration gradient. It moves substances from an area of high concentration to an area of low concentration without requiring energy input.
Which transport mechanisms moves materials across a plasma membrane against an apparent concentration gradient?
active transport
What is the transport of materials against a concentration gradient called?
The process of moving materials against a concentration gradient is called active transport. Active transport generally uses a protein pump to move molecules from an area of low concentration to an area of high concentration; in order to perform an active transport, the cell must use some of its energy to initiate the reaction.
How do transport proteins that are pumps differ from that are channels?
Transport proteins that are pumps differ from those that are channels in that when it pumps, it moves materials against concentration gradient. Other wise, from low to high concentration levels. Channels move materials down a concentration gradient, requiring no energy expenditure by the cell. From high concentration to low concentration levels.
Active transport requires what?
Energy-requiring process by which substances move across the plasma membrane against a concentration gradient.

The transport of a substance across the cell membrane against its concentration gradient is called what?
The transport of a substance across the cell membrane against its concentration gradient is called active transport.
What is required when cells must move materials against a concentration gradient?
Active transport which requires ATP.
The transport of materials against the concentration gradient is called?
In biology (and cut potatoes in baths) this process is called Osmosis; in the Water Purification Industry the process called Reverse Osmosis is employed.
