9.1 stages of cellular respiration

Question 1

3 stages

Answer 1

1-glycolysis
2-citric acid cycle
3-oxidative phosphorylation (ETC and chemiosmosis)

Question 2

where is glycolysis

Answer 2

cytosol

Question 3

what happens in glycolysis

Answer 3

breaks glucose down into 2 molecules of pyruvate

Question 4

citric acid cycle where

Answer 4

mitochondrial matrix

the cytosol of prokaryotes

Question 5

citric acid cycle what happens

Answer 5

oxidizes a derivative of pyruvate to carbon dioxide

completes breakdown of glucose

Question 6

oxidative phosphorylation where

Answer 6

inner membrane of mitochondria

plasma membrane of prokaryotes

Question 7

oxidative phosphorylation

Answer 7

NADH is formed
ETC
forms water in the end of the ETC
the energy released is stored to make ATP

Question 8

substrate level phosphorylation

Answer 8

makes small amount of energy by

• an enzyme directly transferring a phosphate group from a substrate molecule to ADP
• rather than adding an inorganic phosphate to ADP

Question 9

for each molecule of glucose degraded to CO2, _______ molecules of AT Pare made and _______of free energy

Answer 9

38

7.8kcl/mole of free energy
