Unit 3

Question 1

Cellular Respiration

Answer 1

Cells harvest chemical energy stored in organic molecules and use it to generate ATP

Question 2

Major Source of Fuel for animals

Answer 2

Starch (broken down into glucose)

Question 3

Oxidation of glucose

Answer 3

transfers electron to a lower energy state, releasing energy to use in ATP synthase

Question 4

Oxidation

Answer 4

lose electrons

Question 5

Reduction

Answer 5

gain electrons

Question 6

Cellular Respiration Formula

Answer 6

Glucose +Oxygen = CO2 + H2O + energy

Question 7

Path of Electrons in energy harvest

Answer 7

glucose -> NADH -> ETC -> Oxygen

Question 8

Oxidative Phosphorylation

Answer 8

ETC and chemiosmosis

Question 9

Site of Glycolysis

Answer 9

cytosol

Question 10

Cite of the Citric Acid Cycle

Answer 10

Matrix

Question 11

Chemiosmosis

Answer 11

ATP synthase: H+ gradient creates energy

Question 12

Anaerobic Respiration

Answer 12

ATP using ETC without oxygen

Question 13

Fermentation

Answer 13

ATP without ETC: extension of glycolysis with recycled NAD+

Question 14

Alcohol Fermentation

Answer 14

pyruvate converted to ethanol

Question 15

Lactic Acid Fermentation

Answer 15

pyruvate reduced directly by NADH to form lactate

Question 16

Photosynthesis

Answer 16

solar energy to chemical energy

Question 17

ototrophs

Answer 17

use photosynthesis

Question 18

stromata

Answer 18

pores where CO2 and O2 enter and exit

Question 19

grana

Answer 19

stacked colums of chlorophyll

Question 20

stroma

Answer 20

fluid in chloroplasts

Question 21

Photosynthesis equation

Answer 21

6Co2 + 6H20 + light energy = C6H12O6 + 6O2

Question 22

Colors best absorbed by chlorophyl

Answer 22

red & blue wavelengths (least in green)

Question 23

Photosytem II wavelength

Answer 23

680

Question 24

Photosytem I wavelength

Answer 24

700

Question 25

Redox Process

Answer 25

Photosynthesis is this: H2O is oxidized and CO2 is reduced

Question 26

The electron donor in Photosynthesis

Answer 26

H20

Question 27

Calvin Cycle

Answer 27

Builds sugar using ATP and the reducing power of electrons carried by NADPH

Question 28

3 phases of the Calvin Cycle

Answer 28

1. Carbon Fixation (catalyzed by rubisco, uses ATP) 2. Reduction 33. Regeneration of the CO2 acceptor (RuBP)
