What else can I help you with?
A specific protein that recognizes certain molecules bringing them across the membrane?
The protein you are referring to is likely a transporter protein, which is responsible for facilitating the transport of specific molecules across the cell membrane. These transporter proteins bind to their target molecules on one side of the membrane and undergo a conformational change to transport the molecules to the other side. Examples include glucose transporters and ion channels.
What is a specific protein that recognizes certain molecules?
balls
What do you call a cell membrane that allows certain molecules to pass through?
A selectively permeable membrane.
What does it mean if a cell membrane is selectively permiable?
The cell membrane only allows certain molecules through.
A specific protein that recognizes certain molecules?
There are antibodies and cell-surface receptors and enzymes; is there a more specific A. in view?
Why do you think that the eggs membrane will let water to enter but not corn syrup?
water molecules are smaller than corn syrup. the membrane allows a certain size of molecules.
Why can't charged molecules pass through the membrane?
Charged molecules cannot pass through the membrane because the membrane is selectively permeable, meaning it only allows certain substances to pass through based on their size and charge. The charged molecules are repelled by the hydrophobic interior of the membrane, which prevents them from crossing.
What is the ability of certain hormones to attach to a cell determined by?
receptor molecules in the cell membrane
What is the term for a membrane that allows certain but not all molecules to diffuse through it?
semi-permeable.
What cell organelle has pores that allow certain molecules to leave and enter it?
Cell membrane
What does semi permeable membrane do?
I semi-permeable membrane is a membrane when only certain substances can pass through it.it is a membrane that will only allow certain molecules through it . in general oxygen , food and water are allowed to enter ; waste products are allowed to exit and harmful substances are kept out. hope this helps.
What is a membrane that only allows certain materials to pass through?
A membrane that permits the passage of only certain molecules is called a semi-permeable membrane. In its simplest form, this separation process is based on molecular size. Smaller molecules pass through and larger ones are retained. In most biochemical processes, a concentration gradient drives the movement of molecules through the membrane.
