Is active transport low to high?
Yes, active transport moves substances from an area of low concentration to an area of high concentration.
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.
How does active transport enable the movement of substances from a low concentration to a high concentration within a cell?
Active transport is a process in which cells use energy to move substances against their concentration gradient, from an area of low concentration to an area of high concentration. This allows the cell to maintain specific concentrations of substances inside and outside the cell, which is important for various cellular functions.
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 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.
Is active transport low to high?
Yes, active transport moves substances from an area of low concentration to an area of high concentration.
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.
What transport that requires no energy and moves substances from an area of high concentration to a lower concentration?
Your mom...........no I'm just kidding, but there are some cars that regire no energy, but just solar power.
Does active transport move from higher to lower concentration?
Active Transport- When molecules move from an area of lower concentration to an area of higher concentrationPassive Transport- When molecules move from an area of higher concentration ot an area of higher concentration (also called diffusion)

The net movement of water across a membrane from the solution of lower concentration to one of higher concentration is called?
This is referred to as OSMOSIS. When you say "solution of lower concentration" this implies the solute concentration is low, thus water concentration is high. So, osmosis is movement of water from a high concentration of water, to a lower concentration of water, just to be clear.
In which type of process do substances move down their concentration gradient across the membrane?
Active transport is a process that removes substances from a cell against the concentration gradient. The molecules move from low concentration to high concentration during this process.
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.
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.
When a substance moves from an area of low concentration to an area of high concentration while using energy the processed is term is?
When a substance moves from an area of low concentration to an area of high concentration while using energy the process is called active transport.
When do cells do active transport?
When transporting substances from low to high concentration, or when transporting substances too large to pass through the membrane without assistance from a transport protein.
Can passive membrane transport processes include movement of water from an area of low concentration to an area of high concentration?
No, passive membrane transport processes do not involve movement of substances from areas of low concentration to areas of high concentration. Instead, passive processes such as osmosis and diffusion move substances down their concentration gradient, from areas of high concentration to areas of low concentration without requiring energy input.
