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 are three ways molecules move through a semipermeable membrane?
Three ways molecules move through a semipermeable membrane are simple diffusion, facilitated diffusion, and active transport. In simple diffusion, molecules move from an area of high concentration to low concentration without the need for energy. Facilitated diffusion involves the movement of molecules across the membrane with the help of protein channels or carriers. Active transport requires energy and moves molecules against their concentration gradient.
What are two ways cell moves things by active transport?
passive transport and active transport.
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.
Are osmosis and endocytosis passive transports?
It is an active transport,Transport mechanisms fall into two catagories passive and active. Passive transport mechanisms do not require the cell to do work for the substance to enter or leave the cell. Instead the energy involved comes from the kinetic energy of the molecules in solution. Active transport mechanisms involve the cell to use cellular energy usually in the form of ATP to power special protein pumps to bring material into the cell.Passive transport mechanisms Active Transport mechanismsSimple diffusionOsmosisFacilitated DiffusionSimple protein channelsGated channelsActive transport via protein pumpsBulk flow mechanismsendocytosisphagocytosispinocytosisexocytosisThe passive transport mechanisms and the protein pump mechanisms involve movement of substances as single molecules across the membrane. The "bulk" flow mechanisms endocytosis and exocytosis enable the cell to take in very large packages of molecules...say a food item from the environment. Many books treat these bulk flow mechanisms as separate from active transport for that reason.
In what ways do molecules move?
it moves by diffusion, osmosis and active transport
What id the difference between active and passive transport?
Active transport requires energy to move molecules against their concentration gradient while passive transport does not require energy and moves molecules from high to low concentration. Active transport is selective and can transport specific molecules, while passive transport is nonselective and moves molecules based on their concentration gradient.
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.
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.

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.
How can active transport differ from passive transport?
Active transport requires energy input to move molecules against their concentration gradient, while passive transport does not require energy and moves molecules along their concentration gradient. Active transport usually involves the use of transport proteins, such as pumps or carriers, while passive transport relies on diffusion or facilitated diffusion.
What are two ways in which cells use the energy provited by ATP?
Cells use the energy from ATP for active transport and protein synthesis.
Contrast active and passive transpot.?
Active transport requires energy to move molecules against their concentration gradient, while passive transport does not require energy and moves molecules along their concentration gradient. Active transport involves protein pumps or channels that actively move molecules across the cell membrane, while passive transport relies on the natural movement of molecules without the need for additional energy input.
What moves products through a cell membrane?
Molecules pass through the cell membrane via processes like simple diffusion (high to low concentration), facilitated diffusion (with the help of transport proteins), or active transport (against the concentration gradient using energy).
What are two ways the the cell moves things by active transport?
passive transport and active transport.
What are two ways that the cell moves things by active. Transport?
passive transport and active transport.
