Question 9

Gain of electrons

Answer 9

Reduction

Question 10

Factors that affect enzyme activity

Answer 10

Temperature, pH, substrate concentration

Question 11

What happens in glycolysis?

Answer 11

Glucose is split in half and 2 ATP is produced

Question 12

Is glycolysis catabolism or anabolism

Answer 12

Catabolism

Question 13

Energy from the transfer of high-energy PO4 - to ADP generates ATP

Answer 13

Substrate- level phosphorylation

Question 14

Energy released from the transfer of electrons from 1 compound to another is used to generate ATP in ETC

Answer 14

Oxidative Phosphorylation

Question 15

Final electron acceptor is O2

Answer 15

Aerobic respiration

Question 16

Final electron acceptor is not O2

Answer 16

Anaerobic respiration

Question 17

How is anaerobic respiration different from aerobic respiration?

Answer 17

Anaerobic respiration DOESN’T use O2 the final electron acceptor but aerobic respiration does

Question 18

How many ATPs do Prokaryotes generate from the aerobic breakdown of 1 molecule of glucose?

Answer 18

38 ATP

Question 19

Urease biochemical test
Oxidase biochemical test
Fermentation test

Answer 19

Producing urease
Used to detect cytochrome c oxidase
They can ferment a specific carbohydrate

Question 20

What happens in the krebs cycle ?

Answer 20

Oxidation of Acetyl CoA using decarboxylation and redox reaction

Question 21

What happens in the ETC cycle and chemiosmosis ?

Answer 21

In ETC, a series of carrier molecules that are oxidized and reduced as electrons are passed down chain.
In chemiosmosis, it is using released energy to produce ATP.

Question 22

The different types of fermentation

Answer 22

Alcohol and lactic acid fermentation
