Explained really well
von Julianna Z. am 25. Juni 2021 für Allosteric Control – Metabolic Control of Enzyme Activity

I liked the way the R and T states where explained. It all became very clear

 
Worth every minute.
von Olga A. am 31. Juli 2017 für Allosteric Control – Metabolic Control of Enzyme Activity

A great, insightful lecturer. A Prof. at the top of his game. Miss his long hair though (checkout his youtube site)!
