Study Notes

Enzymes and Denaturation

Enzymes are proteins.
They are denatured by extreme temperatures, pH, or other factors that affect protein structure.
Denaturation renders enzymes non-functional.

Action Potential Sequence of Events

Action potentials are a sequence of events that occur in neurons, resulting in the transmission of information.
