Enzymes And Biochemical Reactions (Biology)

Question 1

What critical task do enzymes perform

Answer 1

Lowering a reactions activation energy

Question 2

A substance that speeds up a chemical reaction without being changed

Answer 2

Catalyst

Question 3

A biological catalyst (usually a protein)

Answer 3

Enzyme

Question 4

The reactant molecule that an enzyme works on

Answer 4

Substrate

Question 5

The part of the enzyme where the substrate binds

Answer 5

Active site

Question 6

How do enzymes lower activation energy

Answer 6

By binding to a substrate and holding it in a way that allows the reaction to happen more efficiently

Answer 10

Ase

Question 11

If the graph starts at 4 and ends at 10, what is 4-10

Answer 11

The range

Question 12

If the line never touches 12 and 14 what is that part

Answer 12

No enzymatic activity

Question 13

What is the optimum ph of the enzyme

Answer 13

8

Question 14

If an enzyme is under 7 ph

Answer 14

Acidic

Question 15

If an enzyme is over 7 ph

Answer 15

Basic

Question 16

If an enzyme is exactly 7 ph

Answer 16

Neutral

Question 17

Why do our bellies make noise

Answer 17

Because it is acidic

Question 18

What does competitive inhibitor do

Answer 18

Goes to enzymes active site, causing the substrate to no longer bind

Question 19

What are the 2 internal body condition factors

Answer 19

Temperature and Ph

Question 20

What are the environmental conditions

Answer 20

Enzyme/substrate concentration and competitive inhibitor

Question 21

What organic molecule are enzymes made of

Answer 21

Proteins

Question 22

What happens to water when exposed to 100 degrees Celsius

Answer 22

Begins go boil and molecules evaporate

Question 23

What happens when proteins go through 100 degrees Celsius

Answer 23

They change shape and denaturation

Question 24

What specific changes happens to enzymes to make them stop working

Answer 24

Denaturation

Question 25

What happens when an active site gets deformed and loses shape

Answer 25

Loss of biological activity
