What do cell membranes allow?
Cell membranes allow the regulation of what enters and exits the cell, maintaining cell homeostasis. They also provide structural support and separate the cell's internal environment from the external environment. Additionally, cell membranes facilitate cell communication and recognition.
Where an enzyme and substance meet or connect?
Membrane Proteins, or transport site, these sites act as transporters, enzymes, cell surface receptors and cell surface identity markers, as well as aiding in cell-to-cell adhesion and securing the cytoskeleton.
What forms of vesicular transport processes are used by flu viruses diphtheria and cholera toxins to enter your cells?
Flu viruses enter cells through endocytosis, a process where the cell engulfs the virus in a vesicle formed from the cell membrane. Diphtheria toxin enters cells through receptor-mediated endocytosis, where the toxin binds to a cell surface receptor and is internalized. Cholera toxin is taken up by clathrin-dependent endocytosis, where the toxin binds to a receptor on the cell surface and is internalized in clathrin-coated vesicles.
Cell membranes usually allow what substances to enter a cell?
Cell membranes usually allow water, gases (such as oxygen and carbon dioxide), and small uncharged molecules to enter a cell. Larger molecules or charged ions may require specific transport proteins or channels to cross the membrane.
What is it called when a part of a cell membrane closes around a molecule to allow the molecule to enter the cell?
This is called endocytosis.
Which type of receptors binds to ligands that cannot enter the cell?
Extracellular
How substance are able to enter and exit a cell?
osmosis
What is agonsit?
An agonist is a chemical that binds to a receptor of a cell and triggers a response by the cell. An agonist often mimics the action of a naturally occurring substance.
Which substance can enter a cell by diffusion without have to be digested?
water
What is the characteristic of a cell membrane that control which substance can enter and exit the cell?
Selective permeable
What is a characteristic of a cell membrane that controls which substance can enter and exit the cell?
Selective permeable
What is the characteristic of a cell membrane that controls which substance can enter and exits the cell?
Selective permeable
What is the characteristic of cell membrane that controls which substance can enter and exit the cell?
Selective permeable
A protein on the cell membrane binds and recognized to specific substance is called a?
It is called a receptor protein.

When this is taken up by the cell it binds to the repressor so that the repressor no longer binds to the operator?
The inducer.
