How does active transport differ from passive transport in terms of their mechanisms and energy requirements?
Active transport and passive transport are two different processes by which substances move across a cell membrane. Passive transport does not require energy and relies on the natural movement of molecules from an area of high concentration to an area of low concentration. Active transport, on the other hand, requires energy in the form of ATP to move molecules against their concentration gradient, from an area of low concentration to an area of high concentration. This difference in energy requirements is what distinguishes active transport from passive transport.

How is active transport different from passive transport, and what are two ways in which they contrast in terms of their mechanisms?
Active transport and passive transport are two methods by which substances move across cell membranes. Active transport requires energy input from the cell, usually in the form of ATP, to move molecules against their concentration gradient. In contrast, passive transport does not require energy and relies on the natural movement of molecules from areas of high concentration to low concentration. One way in which active and passive transport contrast in terms of their mechanisms is that active transport uses specific carrier proteins to transport molecules, while passive transport can occur through simple diffusion or facilitated diffusion. Another difference is that active transport can move molecules in both directions across the membrane, while passive transport typically only moves molecules in one direction.
Are symporters active or passive in their transport mechanism?
Symporters are active transport mechanisms that move molecules across a cell membrane using energy from ATP or an electrochemical gradient.
Compare active transport to passive transport?
Active transport requires energy, whereas passive transport does not. Passive transport is normally something moving from an area of high concentration to low concentration (with the grain). Active transport is something moving from an area of low concentration to an area of high concentration(against the grain).
Passive and active transport?
Passive transport does not require energy to move molecules across a cell membrane, relying on concentration gradients, while active transport requires energy in the form of ATP to move molecules against their concentration gradients. Passive transport includes diffusion, facilitated diffusion, and osmosis, while active transport involves pumps, such as the sodium-potassium pump, and vesicle transport mechanisms like endocytosis and exocytosis.
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.
Is water an active or passive transport?
Water can use both passive and active transport mechanisms. Passive transport involves movement of water molecules across a membrane without the need for energy, while active transport involves the use of energy to move water molecules against their concentration gradient.
Are symporters active or passive in their transport mechanism?
Symporters are active transport mechanisms that move molecules across a cell membrane using energy from ATP or an electrochemical gradient.
What is differs between active transport and passive transport?
Active transport requires energy; passive transport does not.
The difference between active transport and passive transport is?
Active transport requires energy; passive transport does not.
How does active transport differ from passive transport-?
Active transport requires energy while passive transport does not.
Is transport proteins active transport or passive transport?
passive
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.
Is active or passive transport hypertonic?

What is the dif frence between active and passive transport?
Active transport requires energy, passive transport does not.
Is an active transport active or passive?
It has is in the name. Active Transport
What is the name of the process of how things get in and out of the cell?
The process by which substances enter and exit the cell is called cellular transport. It primarily occurs through two main mechanisms: passive transport, which does not require energy, and active transport, which requires energy expenditure by the cell. Examples of passive transport include diffusion and osmosis, while examples of active transport include endocytosis and exocytosis.
