What process the cell must use to allow the protein to enter and why?
The process the cell must use to allow the protein to enter is rather simple and uncomplicated. The cell uses the process of osmosis and diffusion along a concentration gradient to allow for passage in and out of the cell.
What controls diffusion and osmosis in and out of a cell?
the nucleus controls both osmosis and diffusion in and out of a cell
How are diffusion and facilitated diffusion similar?
Substances enter a cell through the cell membrane
What gas moves into or out of cell diffusion?
Oxygen moves into the cell and Carbon Dioxide moves out of the cell due to diffusion
What is is called when vesicles are used to move substances out of the cell?
The process that requires transport vesicles to transfer material out of a cell is called exocytosis.
Where diffusion occur?
Diffusion occurs on the cell membrane.
What cell part plays a role in diffusion?
The plasma membrane of a cell plays a role in diffusion.
What 3 ways can substances enter and leave a cell?
Substances can move in and out of a cell in several ways. Diffusion is when a substance will distribute itself in or out of a cell until the distribution on both sides of the cell is balanced. Active transport is when a cell transports a substance across the cell membrane that would not normally be able to pass through. Osmosis is the movement of water from areas with few dissolved dissolved substances to areas with high dissolved substances.
How does water get into cells?
i think it is because diffusion that water gets into the cells of few organisms. The specific type of transport used is osmosis. Diffusion is the net movement of substances typically from a rgion of high concentration to low concentration. This process does not require energy. Osmosis is diffusion but is specific to water.
How does osmosis and diffusion limit the size of a cell?
diffusion and osmosis limit the size of a cell by how fast is can move
When particles move out of a cell through diffusion the cell?
If the diffusion is moving particles from higher to lower concentration, it uses no energy from the cell; this is passive diffusion. However, if it is active diffusion, the cell is pumping out specific molecules into a higher concentration, therefore using energy.
What used a protein to move a molecule across a cell membrane without energy?
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
