What is it called a molecule moves across a membrane through a protein channel without using energy?
Passive Transport
Why might material need energy to move through the cell membrane?
Materials may need energy to move through the cell membrane against their concentration gradient, which is known as active transport. This process requires cellular energy to pump molecules or ions across the membrane. Without energy, the movement of materials across the cell membrane would rely solely on passive processes like diffusion, which may not be sufficient for maintaining proper cellular functions.
What best describes passive transport?
it moves materials from areas of high concentration to areas of low concentrationit moves materials of high concentration to areas of low concentration
What organelle regulates what moves in and out of the cell?
The plasma membrane selectively controls movement of materials into and out of the cell, and has receptors for hormones and enzymes. The generic term for these two processes is endocytosis (material moved into the cell) and exocytosis (movement of material out of the cell).
A non-energy requiring process that moves materials across a cell membrane with the concentration gradient.?
Passive transport is a non-energy requiring process that moves materials across a cell membrane with the concentration gradient. This process includes simple diffusion, facilitated diffusion, and osmosis.

What is a substance that moves across a cell membrane without using the cells energy tends to move?
away from the area where it is more concentrated
The process that moves materials through a membrane against a concentration diffrence is known as?
This process is known as active transport; needing ATP energy to complete the process.

What is the movement of materials across a membrane that requires energy input called?
Active transport is the movement of materials across a membrane that requires energy input, typically in the form of ATP. This process allows cells to move molecules against their concentration gradient, ensuring the proper balance of ions and molecules inside and outside the cell.
