 What is the difference between caffeine and chocolate?

Caffeine is a stimulant, but chocolate is not

Caffeine is a molecule, chocolate is not

Caffeine and chocolate are highly related molecules, differing by a single functional group

Caffeine is a drug, but chocolate is not
o Previously learned material
 One group of neurotransmitters is classified by the fact that all members have the same functional
group. What is that functional group?

You previously learned that the membranes surrounding cells are made up of lipids. In what way is
that lipid covering helpful to cells

What role do proteins have in biological membranes?

If you eat a mushroom, and ingredients in that mushroom acts upon serotonin receptors in a way
that is a lot like serotonin but there are important differences, you would characterize the
ingredients in the mushroom as being:
serotonin agonists
serotonin antagonists
partial serotonin agonists
partial serotonin receptors
