enzymes

Question 1

what is an enzyme

Answer 1

biological catalyst

Question 2

describe in detail the active site theory of enzyme action

Answer 2

-the substrate combines with the active site of the enzyme
-the active site is induced to caused to change shape slightly
-the substrate and enzyme form an enzyme substrate complex. the bonds in the substrate are altered so that the substrate changes into products

Question 3

describe what happens to an enzyme if it is overheated

Answer 3

becomes denatured

Question 4

give one example of a catabolic enzyme and one example of a anabolic enzyme

Answer 4

catabolic - amylase
anabolic - polymerase

Question 5

what is meant specify in relation to enzymes

Answer 5

only acts on one substrate

Question 6

what type of metabolic reaction is the induced fit model

Answer 6

catabolic

Question 7

why is the induced fit model a catabolic reaction

Answer 7

substrate is broken down

Question 8

identify the cell organelle where enzymes,es are produced

Answer 8

ribosome

Question 9

what is meany the enzyme denaturation

Answer 9

loss of shape

Question 10

give one condition that will denature an enzyme,e

Answer 10

unsuitable pH

Question 11

what is an immobilised enzyme

Answer 11

an exam that is fixed

Question 12

give one advantage of using immobilised enzymes

Answer 12

can be reused

Question 13

which type of biomolecule are enzymes

Answer 13

protein

Question 14

name two factors that affect the enzyme action

Answer 14

temperature, pH

Question 15

name the part of an enzyme responsible for its specificity

Answer 15

active site

Question 16

define substrate

Answer 16

the substance with which an enzyme reactsde

Question 17

define product

Answer 17

the substance the enzyme forms

Question 18

define bioprocessing

Answer 18

the use of enzyme controlled reactions to produce a product

Question 19

define bioreactor

Answer 19

a vessel or container in which living cell or their product are used to make a product
