Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The binding that occurs between a signalling molecule and its specific receptor. The specificity of the binding is analogous to that of a particular key in a particular lock; e.g. the binding between a neurotransmitter and its receptor - or a hormone
