enzymes

Question 1

define the term product

Answer 1

the product is what is formed when the enzyme and subsrtate react

Question 2

define the term substrate

Answer 2

substrate is the substance the enzyme reacts with

Question 3

describe the shape of an enzyme

Answer 3

its a 3-d shape with a region called the active site where it changes shape to fit a substrate

Question 4

state the biomoelcule an enzyme is made from

Answer 4

protein

Question 5

define catalyst

Answer 5

speeds up chemical reaction without being used up in said reaction

Question 6

describe the role of an enzyme

Answer 6

enzymes control chemical reactions

Question 7

describe the effects of temperature on enzymes activity

Answer 7

too low or too high temperature can cause an enzyme to be denatured, optimum temp in humans is 37 degrees and in plants its 20-30 degrees

Question 8

describe the effects of ph on enzyme activity

Answer 8

too low or too high ph can casue the enzyme to be denatured, optimum ph is 7 but in pepsin the stomcah acid its 2

Question 9

define the term optimum activity

Answer 9

optimum activity is the conditions under which enzymes work the best

Question 10

defien the term denatured enzyme

Answer 10

an enzyme that has lost its shape and can cause the substrate to not fit in the active site menaing the enzyme can no longer function

Question 11

define the term immoblized enzyme

Answer 11

immoblized enzymes are trapped in a gel or attatched to eachother

Question 12

describe the formation of immoblized enzymes

Answer 12

cross linking, ceramic beads, entrapped in a gel

Question 13

state the advantages of immoblized enxmes

Answer 13

can be reused so it cuts cost

Question 14

catabolic reacti0ons

Answer 14

convert smaller molecules into larger molecules

Question 15

anabolic reactions

Answer 15

convert smaller molecules into larger molecules

Question 16

enzyme specificity

Answer 16

enzyme reacts with only one particular substate
