Biochemistry of Metabolism Worksheet

Question 1

substrate level phosphorylation

Answer 1

metabolic reaction; transfer phosphate group from substrate to ADP in order to make ATP

Question 2

oxidative phosphorylation

Answer 2

uses chemiosmotic process where movement of substance across a membrane is couple to the chemical reaction
-electron transport chain

Question 3

glycolysis

Answer 3

• phase 1 glucose breakdown/cellular respiration

- breakdown of glucose into pyretic acid (happen in cytoplasm)

Question 4

preparatory reaction/step

Answer 4

• phase 2 glucose breakdown/cellular respiration

- 2 private combine with 2 CoA and leads to 2 acetyl and 2 CO2

Question 5

decarboxylation

Answer 5

chemical reaction that removes the carboxyl group and releases CO2

Question 6

citric acid cycle/kreb cycle

Answer 6

• phase 3 glucose breakdown/cellular respiration
• breakdown of pyruvic to CO2 to small amounts of ATP
• only makes 2 ATP

Question 7

electron transport chain

Answer 7

• phase 4 glucose breakdown/cellular respiration
• energy yielding reaction that splits H removed during oxidation to H+ and e- and create a proton gradient used to bond ADP to P
• forms 34 ATP

Question 8

glycogenesis

Answer 8

formation of glycogen from excess glucose

Question 9

glycogenolysis

Answer 9

breakdown of glycogen in response to low blood sugar

Question 10

gluconeogenesis

Answer 10

make new glucose from non-carbs

Question 11

glycerol pathway

Answer 11

• lipid metabolism

- glycerol – glyceraldehyde phosphate – acetyl COA — kern cycle

Question 12

beta oxidation

Answer 12

• lipid metabolism

- conversion of fatty acid to acetyl CoA – Kreb cycle

Question 13

lipogenesis

Answer 13

excess dietary glucose and fatty acids turned into triglycerides
-making fat

Question 14

lipolyssi

Answer 14

breakdown of fat

Question 15

ketogenesis

Answer 15

making ketones

Question 16

transamination

Answer 16

• protein metabolism
• takine the amine group off amino acid to a keto acid
• transfering amine group

Question 17

oxidative deamination

Answer 17

• -protein metabolism
• amine group comes off and is released as amonia
• adds carbon dioxide to make it urea that we can pee out
