27.6. Find a rate equation to represent the breakdown of cellulose by cellulase in the absence of inhibitor. 27.7. What is the role of cellubiose in the breakdown of cellulose (find the type of inhibition, and rate equation). 27.8. What is the role of glucose in the breakdown of cellulose (find the type of inhibition, and the rate equation). The rate data for these problems are modified from Ghose and Das, Advances in Biochemical Engineering, 1, 66 (1971)
