substrate

Answer 1

adding water to the molecular bonds cleaves the bonds between the monomers

Question 2

hydrolases

Answer 2

aka hydrolytic enzymes

digestive enzymes that break down organic food molecules

Question 3

enzyme assay

Answer 3

the chemical method of detecting the presence of digested substances

IKI assay - detects starch (turns blue-black)
Benedict’s assay - detects presence of reducing sugars, such as glucose or maltose (changes from green to orange to reddish brown w/increasing amounts of maltose)
