lesson 3

Question 1

state the definition meaning of the word substrate

Answer 1

a substrate is a substance which an enzyme can act on

Question 2

what is the definition of the word enzyme

Answer 2

enzymes are what speed up the rate of reaction

Question 3

what is the defenition of products

Answer 3

products are the chemicals produced by the degredation reaction

Question 4

describe what happens in a degradation reaction

Answer 4

is a process where one large substrate is split into two or more smaller products

Question 5

give an example of a degradation reaction name the substrate broken down , the enzyme involved and all the products

Answer 5

when starch is broken down into maltose and glucose by amylase

Question 6

explain the terms specific as applied under substrates

Answer 6

the term means an enzyme can only catalase one particular reaction because the active site only fits snugly with on type of substrate

Question 7

what enzyme can break down starch and what are the products

Answer 7

enzyme - amylase
product - maltose and glucose

Question 8

describe the events occuring in the enzyme degredation reaction

Answer 8

Stage 1 ) the enzyme and substrate are avalible for reaction

Stage 2) the substrate binds to the enzyme to form a enzyme substrate complex

Stage 3 ) product is made and realeased
