What is B3 biology?
The study of animal and plant behaviour will provide opportunities to see how scientists gather data and use it to construct theories that can be scientifically tested, and then to see how these theories are applied to explain further observations.

Where are enzymes and proteins made?
Protease enzymes are responsible for breaking down proteins in our food into amino acids. Then different enzymes join amino acids together to form new proteins needed by the body for growth and repair. Protease enzymes are produced in your stomach, pancreas and small intestine.
