Where does the exchange of materials between a cell and its environment take place?
a cell membrane
What binds to a signal molecule enabling the cell to respond to the signal molecule?
receptor proteins bind to signal molecules
A series of molecules found in the inner membranes of mitochondria and chloroplasts through which electron pass in a process that causes protons to build up on one side of the membrane?
i belive it is electron transport chain
What are 2 types of active transport?
A) Active transport through special transport proteins in the plasma membrane. ATP causes these proteins to change shapes and move materials from low to high concentration. B) Bulk transport - moving large particles through the membrane by endocytosis or exocytosis.
What is the reaction of a base with a protein?
base causes denaturing of protein
Is insulin a neurotransmitter that affects growth?
No. Its a cellular membrane trigger that causes cells to transport sugar across the membrane ( via transport proteins).
How. do carriers proteins transport substances across cell membranes?
Carrier Proteins transport molecules from an area of higher concentration on one side of the membrane to an area of lower concentration on the other side.
What function does ATP serve in mitosis?
Sorry my answer is not too accurate... don't have my bio textbook on me. From memory, ATP phosphorylates the protein that causes active transport. It would give the energy needed for a protein to actively transport the molecule or atom of choice through the pore. Now active transport mitosis? I've never heard of that before. Are you saying that ATP activates a protein (which transfers thing) during mitosis?
What is the name of a surface membrane molecule that causes an immune reaction?
Antigens are surface membrane molecules that cause an immune reaction.
What are the difference of active transport and passive transport?
In passive transport the solute is driven across the cell until both sides of the membrane are equal. In active transport, energy causes the transporter to release the solute to only one side of the membrane.
What are the differ of active transport and passive transport?
In passive transport the solute is driven across the cell until both sides of the membrane are equal. In active transport, energy causes the transporter to release the solute to only one side of the membrane.
What type of membrane transport causes the depolarization phase of the action potential in neurons?
Diffusion
What are the different shapes of active and passive transport?
In passive transport the solute is driven across the cell until both sides of the membrane are equal. In active transport, energy causes the transporter to release the solute to only one side of the membrane.
What characteristics of a water molecule causes its attraction to a cell membrane?
Water molecules are polar This causes them to be attracted to the cell surface, which is also polar in nature
Where does the exchange of materials between a cell and its environment take place?
a cell membrane
What cause the mosaic pattern of the cell membrane viewed from above?
It causes it because the cell of the membrane are not moving. So therefore it is not moving.
What binds to a signal molecule enabling the cell to respond to the signal molecule?
receptor proteins bind to signal molecules
