Metabolism and Cellular Respiration Quiz

Question 1

whats anabolism

Answer 1

when larger molecules are made from smaller ones

Question 2

whats catabolism

Answer 2

breakdown of larger molecules into smaller ones

Question 3

what does the sythnesis of ATP from ADP result from

Answer 3

energy captured as it is liberated from the catabolism of glucose

Question 4

whats glycolysis

Answer 4

breakin gdown of glucose to form pyruvic acid

Question 5

what does anaerobic mean

Answer 5

without oxygen

Question 6

what does oxidation mean

Answer 6

loss of electrons and hydrogen ions

Question 7

whats the objective of glycolysis

Answer 7

generate ATP

Question 8

wehre does glycolysis occur

Answer 8

cytoplasm

Question 9

whats the purpose of cellular respiration

Answer 9

to break down glucose and slowly release it as energy

Question 10

what starts glycolysis and whats the final product

Answer 10

glucose; pyruvic acid

Question 11

how many ATP are generated in glycolysis reaction? whats the net gain?

Answer 11

4 generated, net gain of 2

Question 12

how many ATP are produced if glucose is completely broken down in the presence of oxygen

Answer 12

36

Question 13

how many ATP are prdouced if glucose is broken down without oxygen

Answer 13

2

Question 14

what does fermentation form

Answer 14

lactic acid or ethyl alcohol

Question 15

what happens to the pyruvate prdouced in glycolysis if oxygen is avaliable

Answer 15

enters mitochondrie, gets oxidized, forms acetyl CoA which gets oxidized in the krebs cycle

Question 16

what happens to pyruvate produced in glycolysis if oxygen is not availabe

Answer 16

stays in the cytoplasm and reduced to form lactic acid or ethyl alcohol

Question 17

how many ATP does heach NAD 2H molecule make

Answer 17

3

Question 18

how many ATP deoes each FAD 2H molecule produce

Answer 18

2

Question 19

what is the net yeild of glycolysis

Answer 19

2 ATP, 2 NAD 2H

Question 20

what is the net yeild of puryvate to acetyl CoA

Answer 20

2 NAd 2H

Question 21

whats the net yeild of the krebs cycle

Answer 21

2 ATP, 6 NAD 2H, 2 FAD 2H

Question 22

whats the total net yield in cellular respiration

Answer 22

4 ATP, 10 NAD 2H, 2 FAD 2H

Question 23

where does electron transport occur

Answer 23

mitochondira

Question 24

what does electron transport do

Answer 24

energy is released from the electrons which is used to phosphorylate ADP to ATP making oxygen the ultimate electron aceptor and causing the formation of water

Question 25

where does electron transport occur

Answer 25

mitochondria
