What is it called a molecule moves across a membrane through a protein channel without using energy?
Passive Transport
What is it called when 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?
The materials don't need energy its the cell that needs energy to pick up the material. The process in which a cell gathers materials while using its energy is call Active Transport. There are several ways in which the cell can pick up materials. It can wrap its membrane around it and form a vacuole or storage space for it. Or it can send some of its proteins to go and get it. There are also many more ways but those were just a few. To do these things cost the cell energy. There is a way although, for the cell to gather materials without using its energy. This is called Passive Transport. This can occur when there is a high concentration of water molecules outside of the cell, and a low concentration inside. The water naturally moves into the low concentrated area and it brings the dissolved materials with it.
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.?
The process of moving materials across the cell membrane without the expenditure of energy is called passive transfer
Does osmosis use energy?
No, it moves water across a partially permeable membrane (cell membrane) from an area of high concentration to an area of low concenration without energy
What is is when a molecule moves across a membrane through a protein channel without using energy?
Passive Transport
What is it called when a molecule moves a membrane through a protein channel without using energy?
passive transport
What is the movement of materials across a membrane that requires energy input called?
Active transport requires energy and proteins to move the materials across the cell membrane. This is in contrast to osmosis, which doesn't require energy to move the material.

What is folded membrane that moves materials through the cell?
endoplasmic reticulum
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 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
