Does enzymes catalyze specific chemical reactions because the shape of their active site allows only certain substrate molecules to enter?
Yes.
Large molecules are surrounded by the cell membrane and enter the cell?
A large molecule that can not enter the cell through myosis enters the cell through by endocytosis. Endocytosis is an example of 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.
Which part of a cell allows nutrients and other materials to enter or leave the cell?
Transport proteins allow nutrients to enter and leave cells. Transport proteins are peppered throughout the cell membrane. Most molecules need the transport proteins to enter or leave the cell, but it's possible for some molecules, like water, to diffuse through the membrane by osmosis.
What are the Four ways materials can enter a cell?
Diffusion, filtration (hydrostatic pressure), active transport, and vesicular transport.
Diffusion with a channel protein?
They are the channels by which molecules enter in facilitated diffusion.
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.
How do nutrients first enter a cell?
nutrient are broken down before entering the cell.small parts of nutrients are taken inside a cell be diffusion and passive transport. there is no energy usage this kind of transport. but there are some big molecules that can not enter cell membrane. so there are taken by active transport.(there is a energy usage in active transport).
Why is active transport of molecules necessary?
To move substances from low to high concentration.

Yes.

What kinds of material enter a cell by active transport?
osmsis
How do large food particles enter amoeba?
Active transport
Could an organism survive only by using passive transport never active transport?
There's an almost infinite number of organisms out there and I wouldn't be overly surprised if some could, but generally speaking, cells need active transport to maintain control over the substances entering and exiting. At the expense of some enrgy, active transport allows cells to control to some extent the molecules that are allowed to cross the plasma membrane. A basic example would be to say that in most human cells, waste products are secreted by active transport so without such a process there would be a toxic buildup in the cell; and also that glucose requires active transport to enter a cell so without it, the cell would have no form of energy and die
What allows material to pass in and out the cell?
what allows all materialsto move in and out of the cell Diffusion and osmosis are natural processes of molecules moving in and out of cells from an area of low concentration to one of high concentration across a semi permeable membrance. This requires no energy. Active transport is used to transport molecules against the concentration gradient, and requires the expenditure of energy. Hope that's what you wanted.
