Looking for good tie-ins: precalculus/chemistry/biology

Does anyone know of some problems in trigonometry or linear systems that arise in chemistry or biology? We are teaching these linked courses, and we can't find any good ones.

Thanks.

These are topics (with the exception of sinusoidal waves) I present in biochemistry:
1. Sinusoidal wave function and repetitive behavior like heart rate
2. Velocity = d[P]/dt in enzyme kinetics.
3. Henderson-Hasselbach:
pH = pK + log [A-]/[HA]
4. Rate equation: K = e^-deltaG/RT;
deltaG = -RTlnKeq
5. Binding curves for oxygen to hemoglobin and myoglobin:
Y = pO2/pO2 + K

...to name a few.
