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.
Gibberellin Role in Barley Germination
- Gibberellin is a plant hormone that plays a crucial role in the germination of barley.
