1. Which of the folowing statements about glucokinase and hexokinase (that catalyze the same reaction) is TRUE? A. Glucokinase has a higher capacity than hexokinase to convert glucose to glucose 6 phosphate B. Hexokinase is only active in the liver where it can utilize multiple hexoses C. While glucokinase requires ATP for its action, hexokinase requires GTP D. Glucokinase can act on multiple glucose-like sugars (such as galactose) E. Hexokinase has a higher Km and easily handles all the glucose...
2. Which of the following statements is true of cyclic forms of 6-carbon sugars? a. Conversion of the linear form to the cyclic form results from a reaction between the 0 3 carbonyl C and an alcohol in the same molecule. b. Six-C sugars only form 6-membered rings c. The cyclic form has the same number of chiral centers as the linear form. d.xAt room temperature in aqueous solutions, glucose is primarily in the linear form Both a and b...
