Answer 3

fermentation

Question 4

name the 3 carbon molecules produced when glucose is broken in half during glycolysis

Answer 4

pyruvic acid (pyruvate)

Question 5

since fermentation doesn’t require oxygen it is said to be

Answer 5

anaerobic

Question 6

since cellular respiration requires oxygen it is said to be

Answer 6

aerobic

Question 7

which high energy electron carrier us regenerated during fermentation that allows cells to continue to make ATP using glycolysis

Answer 7

NAD+

Question 8

complete overall chemical equation for cellular respiration

Answer 8

C6H12)6 + 6O2 —> 6CO2 + 6H2Oh + Energy(ATP)

Question 9

how are the photosynthesis equation and cellular respiration equation related

Answer 9

they are the opposite of one another

Question 10

alcohol fermentation equation

Answer 10

NADH + pyruvate —> CO2 + Ethanol

Question 11

lactic acid fermentation equation

Answer 11

NADH & pyruvate —> NAD+ & lactate

Question 12

yeast uses this kind of fermentation to make bread dough rise

Answer 12

alcoholic

Question 13

your muscle cells use this during rapid exercise when oxygen is low

Answer 13

lactic acid

Question 14

why don’t you become intoxicated from eating bread if yeast uses alcoholic fermentation

Answer 14

the ethanol evaporates because of the high temperatures while baking in the oven

Question 15

correct sequence of AEROBIC cellular respiration

Answer 15

Glycolysis, Krebs Cycle, ETC

Question 16

where do carbon atoms in pyruvic acid end up following the Krebs Cycle

Answer 16

they become part of the CO2 molecule and end up in the atmosphere

Question 17

how many total ATP molecules are produced by 1 molecule of glucose completing aerobic cellular respiration

Answer 17

36

Question 18

what is produced during the Krebs Cycle

Answer 18

ATP, NADH, FADH2

Question 19

What molecule is the final electron acceptor at the end of ETC

Answer 19

oxygen

Question 20

why is water a product of aerobic respiration

Answer 20

h+ (hydrogen) atoms are added to oxygen and it joins together to make water

Question 21

what moves across the membrane from the intermembrane space to the matrix causes ATP synthase to spin and make ATP

Answer 21

H+ ions

Question 22

What stage of cellular respiration produces the most ATP? How much do each of them produce?

Answer 22

***ETC=32
Krebs Cycle=2
Glycolysis=2

Question 23

what happens as electrons pass down the ETC

Answer 23

1. energy from the moving electrons transport H+ ions into the intermembrane space
2. energy from the H+ ions crossing back into the matrix causes ATP synthase to make ATP
3. water is produced
