How does passive transport move substances across a cell membrane in the direction of their concentration gradient?
Passive transport moves substances across a cell membrane in the direction of their concentration gradient without requiring energy input from the cell. This process relies on the natural movement of molecules from areas of high concentration to areas of low concentration, facilitated by protein channels or carriers in the cell membrane.
What else can I help you with?
Does passive transport move substances with the concentration gradient?
Yes, passive transport moves substances with 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.
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.
Is passive transport able to occur against the concentration gradient?
No, passive transport cannot occur against the concentration gradient. It only moves substances from an area of high concentration to an area of low concentration.
Does passive transport move substances with the concentration gradient?
Yes, passive transport moves substances with 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.
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.
Why does active transport allow cells to accumulate substances in high concentrations where as passive means of transport do not?
Active transport uses energy from ATP to carry substances such as glucose to areas where it is required through the use of transport proteins. Whereas, facilitated diffusion is a passive process by which molecules move from an area of high concentration to an area of low concentration and it also depends on kinetic energy. Meaning that the distribution of molecules by facilitated diffusion will be random, whereas, active transport will have control over the direction of the concentration gradient.
Is passive transport able to occur against the concentration gradient?
No, passive transport cannot occur against the concentration gradient. It only moves substances from an area of high concentration to an area of low concentration.
What moves against the concentration gradient in biological systems?
In biological systems, active transport moves substances against the concentration gradient.
Which cell process will remove substances against a concentration gradient?
Active transport
How does difference in concentration relate to movement of substances across the membrane?
the concentration gradient will help to bring stuff into the cell and to move stuff out. Osmosis likes to move with the concentration gradient. Moving with a concentration gradient is passive transport and moving against it is active transport
What is the purpose of active transport?
Active transport expends energy to move substances against a concentration gradient.
What is the energy source for co-transport?
The energy source for co-transport is typically the concentration gradient of one substance that is established by an active transport process. This concentration gradient drives the movement of another substance against its own concentration gradient through a symporter protein.
What proceeds against a concentration gradient?
Molecules can move against concentration gradient by a movement called active transport. Molecules move from an area of low concentration to an area of high concentration by using chemical energy called ATP or an electrochemical gradient--either way, it uses cellular energy.
