co2, h20

Question 15

what molecule is transfered to o2 to make h20

Answer 15

hydrogen

Question 16

at what speed is the energy in glucose REALEASED

Answer 16

slowly and subtley

Question 17

what percent of our food intake goes to heat energy

Answer 17

90%

Question 18

what role does ATP synthase have in cellular respiration

Answer 18

is fueled by hydrogen to make ATP

Question 19

how is ATP formed

Answer 19

when a phosphate is broken up the bond breaking releases atp

Question 20

what are the steps of aerobic pathway in order

Answer 20

glycolysis, Krebs cycle, electron transport

Question 21

what happens to the molecules in the krebs cycle when they are released

Answer 21

they go through the electron transport chain and get recharged to be reused

Question 22

where does gycolysis occur

Answer 22

cytoplasm

Question 23

where does the Krebs cycle occur

Answer 23

in the matrix inside the michtochondria

Question 24

where does lactic acid fermentation and alcoholic fermentation occur

Answer 24

cytoplasm

Question 25

what do products of the Krebs cycle drop off in the electron transport chain

Answer 25

hydrogen

Question 26

if the pyruvate molecule goes down the aerobic pathway what is it converted into for the krebs cycle

Answer 26

2 acetyl COA

Question 27

what are the products and reactants of lactic acid fermentation

Answer 27

reactants- 2 pyruvate , NADH products- NAD+, 2 lactate

Question 28

what are the products and reactants of alcoholic fermentation

Answer 28

reactants-NADH, 2 pyruvate products- co2, NAD+, 2 ethanol

Question 29

what does g3p do in cellular respiration

Answer 29

a step after glycolysis it helps split the glucose into pyruvate

Question 30

what are the three steps of gycolysis in order

Answer 30

investment- where 2 ATP come in cleavage- where glucose gets split with G3P into pryruvate energy harvest- where 2NAD+ get converted into 2 NADH and the 2ADP gets converted into 2 ATP

Question 31

can gylcolysis happen to any molecule?

Answer 31

yes

Answer 32

reactants- nad+, FAD , ADP, acetyl COA, products- Co2 {waste product} NADH, fadh2, atp, coA

Question 33

what is substrate phosphyorlation

Answer 33

when a phosphate attches to a molecule

Question 34

what is chemiosmotic phosphorylation

Answer 34

when a phosphate attached to ADP molecules making atp through it flowing through the membrane by chemiosmsis
