What is the job a a receptor molecule?
A receptor molecule is a molecule that receives information from outside the cell. They are embedded in either the plasma membrane or cytoplasm of a cell. A specific molecule on the surface or inside of a cell with a characteristic chemical and physical structure. Many neurotransmitters and hormones exert their effects by binding to receptors on cells.
How does a receptor in the membrane transmit a message to the cell?
Receptors detect a signal molecule and perform an action in response.
What part of the cell is like a gate?
In this analogy, the cell membrane is like a wall, keeping what's in the cell inside, and what is outside of the cell out. However, there are "gates" called receptors. Receptors are large protein molecules embedded in the membrane, with one end outside and one end inside. Different gates, or receptors, permit certain things to enter. For example a glucose receptor lets glucose enter the cell. When a glucose molecule passes a glucose receptor, the glucose molecule is attracted to the receptor by an electric charge. It then binds to the receptor, but now the balance of the charges in the protein molecule has been changed, so the protein molecule changes shape. When it changes shape, it pulls the glucose into the cell and then lets go of the glucose. Now the protein is free to return to its original shape, and the glucose is inside the cell.
What is the purpose of receptor proteins?
The intracellular proteins form the most important class of receptors called receptor proteins. Receptor proteins are located in the cytoplasm, cell membrane, or nuclear membrane. 1. Cytoplasmic receptor proteins include those that respond to steroid hormones. Ligand activated receptors may enter the cell nucleus where they modulate gene expression. 2. Receptors within cell membranes may be peripheral or trans-membrane proteins. Many receptors for hormones and neurotransmission are trans-membrane proteins. - a. Metabotropic receptors are coupled to G-proteins, acting through various secondary pathways involving ion channels, enzymes such as adenylyl (adenylate) cyclases, and phospholipases, or PDZ domains. - b. Ionotropic receptors are ligand-activated ion channels that permit entry of ions when the central pore is open. A receptor protein is protein molecule that found embedded in the plasma membrane surface of a cell. It receives chemical signals from outside the cell.

Define receptor of body?
A receptor is located on a cell membrane. Any neuronic transmission, hormone, etc. that cannot get inside of the cell's membrane will sit on the receptor in order to pass its message along to the cell. When the molecule sits on the receptor, it causes a series of reactions to occur inside of the cell. From the series of reactions that occur inside of the cell, the message is passed along, and the cell will perform as indicated by the molecule on the cell receptor.
What is a molecule that is generated when a specific substance attaches to a receptor on the outside of a cell membrane which produces a change in cellular function?

What is a signal transduction pathway?
A signal transduction pathway is a group of proteins that carry out transducing signals (which means it converts signals from outside the cell to a different signal inside the cell). A good example can be viewed when a hormone binds to the receptor in the plasma membrane (outside the cell), the receptor which has now been activated can now interact with intercellular proteins which produce new signals inside the cell.

The concentration of a sugar is high inside a cell and sightly lower outside the cell What is most likley to occur if the sugar molecule can cross the membrabe?
When sugar molecule crosses the membrane the sugar molecule moves to the outside of the membrane. This is taught in science.
