Cellular respiration

Question 1

Reduction

Answer 1

Oxidation reaction -A^e- +B -> A+ B^e-

Question 2

Anaerobic

Answer 2

breakdowns of glucose

Question 3

Catabolic

Answer 3

occurs in both aerobic respirations and anaerobic respiration

Question 4

Glycolysis takes place in ?

Answer 4

Cytoplasm

Question 5

Glycolysis Net Yield

Answer 5

2ATP , 2 NADH, 2 pyruvate

Question 6

Amphibolic Pathway

Answer 6

doesn’t produce much ATP, but
provides electrons to power
oxidative phosphorylation.

Question 7

citric acid cycle takes place

Answer 7

mitochondrial matrix (in
eukaryotes)

Question 8

citric acid net yield

Answer 8

2 ATP, 8 NADH,
2 FADH₂, and 4 CO₂

Question 9

Oxidative phosphorylation

Answer 9

the final stage of aerobic respiration

Question 10

Oxidative phosphorylation occurs in

Answer 10

inner mitochondrial membrane

Question 11

Oxidative phosphorylation net yield

Answer 11

32 ATP

Question 12

*Fermentation

Answer 12

is anaerobic, meaning it occurs in the absence of oxygen. Some cells cannot
use an alternate final electron acceptor, and rely only on glycolysis to produce ATP. NAD+
molecules are recycled by other organic molecules to use again in glycolysis

Question 13

• lactic Acid fermentation

Answer 13

starts with glycolisis
the 2 pyruvates are reduced by NADH to produce 2 NAD+ and 2 lactic acid

Question 14

Ethanol Fermentation

Answer 14

Starts with Glycosis -> pyruvates are decarboxylated -> intermediate acetaldehyde is
reduced by NADH, producing 2
NAD+ and 2 ethanol

Question 15

Glycosis Step 1-3

Answer 15

Priming Reactions

Question 16

Glycosis Step 1-3: Priming Reactions

Answer 16

priming-glucose is converted into fructose 1, 6 bisphosphate, requires two ATP

Question 17

Glycosis Step 4-5

Answer 17

cleavage-fructose 1, 6 biosphate is split -> two glyceraldehyde 3-phosphate (3) and goes into 4ATP, 4ADP

Question 18

Glycolysis Steps 6-10

Answer 18

Oxidation and ATP formatting two G3P are oxidized, 2NAD+ are reduced, two Pi are added to each -> 1,3 bisphosphoglycerate (BPG) -> Two pyruvates, four ATP are generated

Question 19

Proteins

Answer 19

broken down into amino acids followed by deamination (removal of the group ) remainder can be added as intermediates in glycolysis or the citric acid cycle

Question 20

Lipids

Answer 20

broken down into fatty acids and glycerol, fatty acids undergo oxidation-fatty

Question 21

oxidation

Answer 21

fatty acids are converted into acetyl groups and CoA is added -> acetyl- CoA, the process is oxygen-dependent
