Flashcards in semester 1 exam part 4 Deck (30):
1

a flattened membranous sac inside a chloroplast that contains most of the components involved in the light reaction of photosynthesis

thylakoid

2

the molecule that accepts electrons that the chlorophyll a molecules have lost

primary electron acceptor

3

carbon atoms are fixed into organic compounds in

the calvin cycle

4

to produce the same amount of carbonhydrate, C4 plants require less

carbon dioxide than C3 plants

5

which of the following environmental factors will cause a rapid decline in the photosynthesis rate if the factor rises above a certain level

temperature

6

organic compounds that can be made from the products of the calvin cycle include

carbonhydrates, amino acids, and lipids

7

which of the following is not part of the light reactions

carbon fixation

8

the light reactions take place

on the thylakoid membrane

9

during photosynthesis, oxygen is produced when

water is split

10

excited electrons that leave chlorophyll a travel along two electron transport chains, resulting in the production of

NADP

11

a process that relies on a concentration gradient of protons across the thylakoid membrane to synthesize ATP

chemiosmosis

12

the breakdown product of glucose that diffuses into the mitochondrial matrix fro further breakdown is

pyruvic acid

13

glycolysis takes place

in the cytosol

14

the net number of ATP molecules made directly by glycolysis is

2

15

the starting substance of the krebs cycle, which is regenerated at the end of the cycle is

oxaloacetic acid

16

during glycolysis, glucose is

partially broken down and some of its stored energy is released

17

the electron transport chian or aerobic respiration

pumps protons into the space between the inner and outer mitochondrial membranes

18

the krebs cycle

breaks down a two carbon molecule into two molecules of carbon dioxide

19

both lactic acid fermentation and alcoholic fermentation produce

NAD+ from NADH and H+

20

the krebs cycle occurs in the

mitochondrial matrix

21

most of the ATP synthesized in aerobic respiration is made

through chemiosmosis

22

by accepting electrons and protons the oxygen used in aerobic respiration turns into

H20

23

glycolysis begins with glucose and produces

pyruvic acid

24

the electron transport chian is driven by two products of the krebs cycle

NADH and FADH2

25

six carbon compound that is the product of acetyl CoA and oxaloacetic acid is

citric acid

26

cellular respiration in the presence of oxygen is

aerobic

27

before the krebs cycle can proceed, pyruvic acid must be converted into

acetyl CoA

28

which of the following is not a product of the krebs cycle

ethyl alcohol

29

cellular respiration is similar to photosynthesis in that they both

produce ATP
involve chemiosmosis
make PGAL

30

ATP is synthesized in the electron transport chain when which of the following moves across the inner mitochondrial membrane

protons
