Week 6: Respiration and Fermentation

Question 1

Atp definition

Answer 1

The common energy carrier of cells

Question 2

Cellular Respiration

Answer 2

breaks down carbohydrates and other metabolites with the concomitant buildup of ATP

Question 3

Cellular Respiration Stages

Answer 3

Glycolysis, The Krebs Cycle, The Electron Transport Chain

Question 4

Glycolysis occurs in

Answer 4

the cytoplasm of cell

Question 5

Glucose is

Answer 5

broken down into 2 molecules of Pyruvic Acid

Question 6

Glycolysis :

NADH is

Answer 6

produced and carries the high energy electrons to the ETC(last step).

Question 7

Krebs cycle location

Answer 7

matrix of mitochondria

Question 8

NADH and FADH2 carry

Answer 8

high energy electrons

Question 9

Electron Transport Chain location

Answer 9

cristae (inner membranes) of the mitochondria

Question 10

The electron carries

Answer 10

NADH and FADH2

Question 11

H+ions move through

Answer 11

ATP synthase channel to generate the ATP

Question 12

Fermentation

Answer 12

an aerobic process

Question 13

Disadvantage of fermentation

Answer 13

End products: toxic to cells

Question 14

Disadvantage of fermentation reason 2

Answer 14

blood can’t remove all lactate—>muscle fatigue

Question 15

Disadvantage of fermentation reason 3

Answer 15

O2 is needed to restore ATP levels and rid the body of lactate—> oxygen debt

Question 16

Disadvantage of fermentation reason 4

Answer 16

efficiency: far less efficient than the complete breakdown of glucose

Question 17

Advantages of fermentation

Answer 17

Provides a quick burst of ATP energy for muscular activity

Question 18

Answer 19

Yeast fermentation

Question 20

Advantages of fermentation reason 4

Answer 20

Bacterial fermentation
