AP Bio Chapter 7

Question 0

Autotrophs

Answer 0

Produce own food

Question 1

Photosynthesis

Answer 1

Conversion of solar energy into chemical energy

Question 2

Heterotrophs

Answer 2

Consumer

Question 3

Photosynthesis equation

Answer 3

CO2+H2O + Solar energy –> C6H12O6+ O2

Question 4

Stomata

Answer 4

Opening that allows co2 in and oxygen out

Question 5

Chloroplast

Answer 5

Organelle that contains chlorophyll double membrane photosynthesis happens inside organell

Question 6

Thylakoids

Answer 6

Flattened sac in chloroplast

Question 7

Grana

Answer 7

Stack of thylakoids

Question 8

Part of the plant cell

Answer 8

Mesophyll epidermis cuticle guard cell stoma xylem and phloem vascular bundle

Question 9

Chlorophyll

Answer 9

Pigment located inside thylakoids membrane

Question 10

Stroma

Answer 10

Semi fluid in chloroplasts

Question 11

Reduced in photosynthesis equation

Answer 11

Carbon dioxide into sugar gains electrons

Question 12

Oxidized in photosynthesis equation

Answer 12

Water into oxygen loss of electrons

Question 13

NADP+

Answer 13

Co enzyme in photosynthesis that reduces to become NADPH will gain two electrons and h

Question 14

NADPH

Answer 14

Electron carrier that gains two electrons and hydrogen

Question 15

Two steps of photosynthesis

Answer 15

Lift and dark (Calvin cycle)

Question 16

Light reaction

Answer 16

Only occurs with solar energy
Solar energy enters thylakoids
Energizes pigments and electrons( from water)
Electron reaches reaction center attaches to nadp+
Goes down etc releasing ATP that goes to Calvin
Electron reaches reaction center again
Attaches to nadp+ and goes to Calvin cycle

Question 17

Green color

Answer 17

Chlorophyll a and b

Question 18

Color of plants

Answer 18

All of the colors are absored or reflected. Reflected color is color of plant

Question 19

Carotenoids

Answer 19

Reflects orange

Question 20

Non cyclic pathway

Answer 20

Photo system 2

Question 21

Photo system 2

Answer 21

Electrons from water bounces around until it reaches reaction center attaches to nadp+ goes down etc

Question 22

Cyclic

Answer 22

Photo system 1

Question 23

Photo system 1

Answer 23

Gains electron from etc electron reaches reaction center attaches to electron acceptor. If cyclic goes down etc continuously producing ATP for Calvin cycle or attaches to nadph and goes to Calvin

Question 24

ATP synthase

Answer 24

Enzyme that joins p and adp to form ATP

Question 25

Chemiosmosis

Answer 25

Method of producing ATP

Question 26

Calvin cycle

Answer 26

RubP a dive carbon sugar combines with carbon dioxide to form an unstable six carbon sugar Wich breaks apart to two 3 pg which then combine together to form c6h12o6

Question 27

Carbon dioxide fixation

Answer 27

First rep of carbon cycle. RuBP with co2

Question 28

C3

Answer 28

Normal Calvin cycle

Question 29

C4

Answer 29

Co2 combines with PEP a three carbon produces a four carbon oxaloacetate this takes co2 to Calvin cycle Avoid photoresperation

Question 30

Photoresperation

Answer 30

Co2 is released instead of oxygen

Question 31

Cam

Answer 31

Combination co2 with PEP to fix co2 storin it at night during the day the c4 molecule goes through Calvin Minimal photosynthesis but prevents loss of water
