Great explanation of steady state using a graph
By Alina B. on 23. November 2016 for Enzymes and Enzyme Kinetics: Enzyme Catalysis

Thank you so much! The part at the end where the steady state was explained with a graph was especially useful.

A very clear understanding of the basic concepts was developed by Kevin. Good examples and perfect illustrations made everything so easy and interesting.

Excellent presentation
