Unit 3

Question 1

Enzyme

Answer 1

Speeds up reactions

Question 2

Catalyst

Answer 2

(Enzyme) speeds up reactions without using all of their energy

Question 3

Denaturation

Answer 3

Proteins (enzymes) lose shape from high temperature or extreme pH and cannot function

Question 4

Competitive Inhibition

Answer 4

Molecule blocks the active site and the substrate can’t bind

Question 5

Noncompetitive Inhibition

Answer 5

Inhibitor binds somewhere else but changes the shape of the enzyme so the substrate can’t bind

Question 6

Photosynthesis

Answer 6

Converts light energy into chemical energy in plant glucose

Question 7

Light Dependent Reactions

Answer 7

Step one of photosynthesis in the thylakoid membrane; makes ATP and NADPH for the next step

Question 8

Photosystem 2

Answer 8

First step where light is absorbed and water is split to release electrons

Question 9

Photolysis

Answer 9

Splitting of water using light which produces electrons

Question 10

ETC

Answer 10

Electrons travel through proteins

Question 11

Photosystem 1

Answer 11

Reenergizes electrons by passing them to NADP+ to make NADPH

Question 12

Light Independent Reactions

Answer 12

Use CO2 + ATP + NADPH to make G3P

Question 13

G3P

Answer 13

3 carbon sugar made in the Calvin Cycle, used to make glucose and carbs

Question 14

Photophosphorylation

Answer 14

Use light energy to add phosphate to ADP, which makes ATP

Question 15

Cellular Respiration

Answer 15

Break down glucose to make ATP in the mitochondria (glycolysis, krebs, ETC)

Question 16

Matrix

Answer 16

Inside of the mitochondria where the Krebs cycle happens

Question 17

Inter membrane Space

Answer 17

Between inner and outer membrane, where H+ builds up to make ATP

Question 18

Glycolysis

Answer 18

Break glucose into 2 pyruvate to make 2 ATP + 2 NADH

Question 19

Pyruvate

Answer 19

3 carbon molecule

Question 20

Anaerobic

Answer 20

No oxygen needed

Question 21

Krebs Cycle

Answer 21

Break down pyruvate and makes NADH, FADH2, and CO2

Question 22

NADH and FADH2

Answer 22

Carry electrons to the ETC

Question 23

Oxygen forms Water

Answer 23

Oxygen is the final electron accepter at the end of the ETC

Question 24

Chemiosmosis

Answer 24

H+ flows through ATP Synthase like a turbine to make ATP

Question 25

Oxidative Phosphorylation

Answer 25

ETC & chemiosmosis makes 32-34 ATP

Question 26

Protein Gradient

Answer 26

ETC pumps H+ into inter membrane space which creates a gradient

Question 27

Endotherms

Answer 27

Mammals that regulate body temp, which causes them to use more ATP

Question 28

Fermentation

Answer 28

Keep making ATP when oxygen is not available
