What binds to a signal molecule enabling the cell to respond to the signal molecule?
receptor proteins bind to signal molecules
When a signal molecule such as a growth hormone binds to a receptor protein in the plasma membrane it stays on the outside of the cell. How might the inside of the cell know that the signal has bound?
Due to a conformational change of the receptor protein....
When a receptor protein in a cell membrane acts as a enzyme the receptor protein does what?
When a receptor protein acts as an enzyme, the receptor protein activates a second messenger that acts as a signal molecule within the cell. Resources: HOLT Biology Textbook - 9th grade edition Chapter 4, Cells and Their Environment.
Epinephrine acts as a signal molecule that attaches to proteins?
G-protein-linked receptor
The process of transduction usually begins?
When the signal molecule changes the receptor protein in some way.

When the signal molecule changes the receptor protein in some way.
An allosteric receptor embedded in a cell membrane will change shape only?
when a signal molecule fits the shape of the receptor
Why is it important that each receptor protein binds to only one signal molecule?
because every receptor has specific shape on it, which binds with specific molecule.
What is a molecule that acts as signal when it binds to a receptor?
Intracellular receptor
Relaying a message from a receptor protein to a molecule that performs a specific function within a cell is called?
Signal Transduction
Relationship between receptor protein and signal molecule?
Depending on what harmone it is, the hormone will attach to the receptor protein if the shape of the hormone and the receptor protein correspond.
What 3 things can occur when a signal molecule binds to a receptor protein?
1. Change the permeability of membrane. 2. Form a Second messenger. (Amplifies the first signal inside the cell.) 3. Activates enzymes inside the cell. (speeds up reactions inside the cell=catalyze)
What change takes place in the cell membrane if a signal molecule causes a transport protein to open?
A permeability change takes place.
