What is The energy-requiring movement of materials against a concentration gradient?
Active absorption
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.
Does Passive transport uses ATP to move molecules against their concentration gradient?
No, passive transport does not require ATP because it moves molecules along their concentration gradient, from an area of higher concentration to an area of lower concentration. ATP is only required for active transport, which moves molecules against their concentration gradient.
Which transport mechanisms moves materials across a plasma membrane against an apparent concentration gradient?
active transport
Does passive transport move with or against the concentration gradient?
Passive transport moves with the concentration gradient.
Is the movement of substances against their concentration gradient an active or passive process?
The movement of substances against their concentration gradient is an active process.
What moves against the concentration gradient in biological systems?
In biological systems, active transport moves substances against the concentration gradient.
Does active transport move molecules against the concentration gradient?
Yes, active transport moves molecules against the concentration gradient.
Does active transport move substances against the concentration gradient?
Yes, active transport moves substances against the concentration gradient.
Does active transport move substances against their concentration gradient?
Yes, active transport moves substances against their concentration gradient.
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.
What type of transport mechanism goes against the concentration gradient?
Active transport is the type of transport mechanism that goes against the concentration gradient.
