1. Kinetic
2. Potential
3. Heat
4. Chemical

Question 2

Potential energy

Answer 2

Stored energy

Question 3

Heat energy

Answer 3

Heat

Question 4

Chemical energy

Answer 4

Energy stored in the form of chemical bonds (stored in food)

Question 5

Enzymes

Answer 5

Proteins
Without enzymes chemical reactions cannot take place

A+B ————-> C+D
(Reactants) (Products)

Question 6

2 Factors affecting enzyme activity

Answer 6

Temperature
ph
Substrate concentration

Question 7

Diffusion

Answer 7

Substances move from area of high concentration to low concentration to attain equilibrium.

Question 8

Osmosis

Answer 8

Diffusion of water across a semi permeable membrane

Question 9

Isotonic (in osmosis) (animal cells)

Answer 9

When 2 solutes have the same concentration

Question 10

Hypotonic (in osmosis) (animal)

Answer 10

Solution has lower concentration of solutes

Question 11

Hypertonic (in osmosis) (animal cell)

Answer 11

Solution with greater concentration of solutes

Question 12

Turgid

Answer 12

(Hypotonic in plants)

Water coming in

Question 13

Flaccid

Answer 13

Isotonic in plants

Waters going in and out

Question 14

Plasmolyzed

Answer 14

Hypertonic in plants

Water goes out and membrane pulls away from the cell wall

Question 15

ATP

Answer 15

Adenosine triphosphate

Question 16

Active site

Answer 16

Part where substrate and enzyme combine

Question 17

Substrate

Answer 17

A specific substance on which an enzyme reacts

Question 18

Mechanism of action

Answer 18

1. Substrate binds (not connected yet) 2. Form the enzyme substrate complex 3. Substrate is transformed into two separate parts 4. Release of product 5. Reuse of enzyme
