Question: Starch synthase in plants contains a single active site that accommodates ADP-glucose. However, cellulose synthase may contain two UDP-glucose-binding active sites. Given the structural differences

Starch synthase in plants contains a single active site that accommodates ADP-glucose. However, cellulose synthase may contain two UDP-glucose-binding active sites. Given the structural differences between starch and cellulose, explain why two substratebinding sites would promote efficient cellulose synthesis.
