What does it means if a substance moves down its concentration gradient?
If a substance moves down its concentration gradient, it means that it is moving from an area where it has a high concentration to an area where it has a low concentration. This is known as diffusion.
Is carrier mediated passive or active?
Carrier-mediated transport can be either passive or active, depending on the type of carrier protein involved. Passive carrier-mediated transport allows molecules to move down their concentration gradient without requiring energy input, while active carrier-mediated transport moves molecules against their concentration gradient using energy from ATP or an electrochemical gradient.
What is concentration gradient downhill or uphill?
when the solute passes from a higher solute concentration to a lower solute concentration, it is known as concentration gradient downhill. and the reverse is true for uphill. also, down hill transport requires energy which is derived from ATP. uphill transport is not derived from ATP's rather from the random motion of the molecules themselves.
What is it called When a nutrient moves from an area of higher concentration into an absorptive cell where the concentration is lower?
This process is called active transport. It requires energy to move nutrients against their concentration gradient into the absorptive cell.
Explain the difference between active transport and facilitated transport?
Active transport utilizes energy, such as ATP, to move molecules against their concentration gradient across the cell membrane. Facilitated transport, on the other hand, moves molecules down their concentration gradient with the help of transport proteins but does not require energy input.
Compare and contrast between osmosis and facilitated diffusion?
Osmosis is when a solvent moves from a lower concentration to a higher concentration. Facilitated diffusion is when a solvent moves down the concentration gradient through carrier molecules.
What moves against the concentration gradient in biological systems?
In biological systems, active transport moves substances against the concentration gradient.
What does it means if a substance moves down its concentration gradient?
If a substance moves down its concentration gradient, it means that it is moving from an area where it has a high concentration to an area where it has a low concentration. This is known as diffusion.
Does passive transport move with or against the concentration gradient?
Passive transport moves with the concentration gradient.
Is carrier mediated passive or active?
Carrier-mediated transport can be either passive or active, depending on the type of carrier protein involved. Passive carrier-mediated transport allows molecules to move down their concentration gradient without requiring energy input, while active carrier-mediated transport moves molecules against their concentration gradient using energy from ATP or an electrochemical gradient.
How does facilitated transport differ from active transport?
Simple diffusion = flow of small molecules ALONG the concentration gradient, does NOT require energy. facilitated diffusion = flow of molecules ALONG the concentration gradient with help of CARRIER PROTIENS or CHANNELS, does NOT require energy active transport= flow of larger or charged molecules AGAINST their concentration gradient, REQUIRES input of ENERGY in the form of ATP.)
Compare and contrast active transport and facilitated diffusion-?
Active transport requires energy input to move molecules against their concentration gradient, while facilitated diffusion does not require energy and relies on carrier proteins to move molecules down their concentration gradient. Both processes involve the use of proteins to transport molecules across the cell membrane, but active transport can move molecules against their concentration gradient, while facilitated diffusion can only move molecules down their concentration gradient.
Why active transport requires energy?
Active transport requires energy because it moves molecules or ions against their concentration gradient, from areas of lower concentration to areas of higher concentration. This process goes against the natural tendency of molecules to diffuse down their concentration gradient, requiring the input of energy in the form of ATP to drive the transport proteins involved.
What is concentration gradient downhill or uphill?
when the solute passes from a higher solute concentration to a lower solute concentration, it is known as concentration gradient downhill. and the reverse is true for uphill. also, down hill transport requires energy which is derived from ATP. uphill transport is not derived from ATP's rather from the random motion of the molecules themselves.
Does passive transport move substances with the concentration gradient?
Yes, passive transport moves substances with the concentration gradient.
How are active transport and facilitated diffusion different and how are they similar?
Active transport requires energy to move molecules against their concentration gradient, while facilitated diffusion does not require energy and moves molecules down their concentration gradient with the help of carrier proteins. Both processes involve the movement of molecules across a cell membrane but in opposite directions in terms of energy requirement.
What concentration gradient moves when a low concentration moves from an area of a higher concentration?
The low concentration moves down its concentration gradient from an area of high concentration to an area of low concentration. This process is driven by diffusion, where particles move spontaneously from regions of high concentration to regions of low concentration until equilibrium is reached.
