- B Galactose
- C Ribose
- D Glucose
Correct answer: D. Glucose
Explanation: Cellulose is a polysaccharide made of glucose monomers linked by beta-1,4-glycosidic bonds. It forms plant cell walls.
As substrate concentration rises, reaction rate increases steeply at first, then plateaus at Vmax once every enzyme molecule is working at full capacity; Km is the substrate concentration giving half-maximal rate, and a LOWER Km means the enzyme reaches that rate with less substrate (higher affinity).
