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.
What are three ways molecules can cross the cell membrane?
Molecules can cross the cell membrane through simple diffusion, facilitated diffusion via transporter proteins, and active transport using energy to move molecules against their concentration gradient.
Can water enter a cell by active transport?
There are two ways that the molecules (i.e: water) move through the membrane: passive transport and active transport. Active transport requires that the cell use energy that it has obtained from food to move the molecules (or larger particles) through the cell membrane. Passive transport does not require such an energy expenditure, and occurs spontaneously.
What are the three ways that things move in and out of the cell?
Things can move in and out of a cell through passive diffusion, facilitated diffusion, and active transport. Passive diffusion involves movement down a concentration gradient without the need for energy input, while facilitated diffusion involves the use of transport proteins. Active transport requires energy input to move molecules against their concentration gradient.

There are two main ways in which molecules are transported into and out of cells - active transport and passive transport. Which of the following statements is true of passive transport?
Carrier proteins are sometimes used during passive transport.

Which are passive and which are active ways of crossing the plasma membrane?
Passive ways of crossing the plasma membrane include diffusion and facilitated diffusion, where substances move across the membrane down their concentration gradient without the use of energy. Active transport, on the other hand, requires energy, typically in the form of ATP, to move substances against their concentration gradient. Examples of active transport include the sodium-potassium pump and endocytosis. Overall, passive transport relies on natural concentration differences, while active transport requires energy input.

Passive transport does not require such an energy expenditure, and occurs spontaneously.
What are the different ways in transporting materials across the membrane?
through several ion channels,communication junctions(eg;gap junction)active transport,passive transport etc

Active transport requires energy input to move molecules against their concentration gradient.
Why does it take energy to transport some things across the cell but it doesn't take energy to transport other things?
there are two ways to transport things into a cell: active and passive transport. In active transport the cell has to physical engulf whatever it needs from outside the cell. In passive transport, if something inside the cell has less of the item that is outside of the cell, the things outside of the cell go into the cell until the number is balanced. This happens automatically so it doesn't involve energy.
