4.3 Cellular Respiration

Question 1

What is the order of the stages of Cellular Respiration?

Answer 1

starts with glycolysis, link reaction, the kreb’s cycle, then the electron transport chain

Question 2

What are the inputs and outputs of glycolysis?

Answer 2

inputs: glucose and ADP
outputs: pyruvate and glucose

Question 3

What are the inputs and outputs of the kreb’s cycle?

Answer 3

inputs: ADP
outputs: CO2 and ATP

Question 4

What are the inputs and outputs of the electron transport chain?

Answer 4

inputs: ADP and oxygen
outputs: water and a TON of ATP

Question 5

What is the location of glycolysis?

Answer 5

cytoplasm

Question 6

What is the location of the link reaction/kreb’s cycle?

Answer 6

mitochondria

Question 7

What is the location of the electron transport chain?

Answer 7

inner membrane of mitochondria

Question 8

What is the overall chemical equation of cellular respiration?

Answer 8

C6H12O6 —> 6CO2 + 6H2O

Question 9

What happens if there is no oxygen in your cell for these processes?

Answer 9

fermentation, there are two types, alcoholic and lactic acid fermentation

Question 10

What do both types of fermentation have in common?

Answer 10

starts with pyruvate, both occur during lack of oxygen, and both regenerate NAD+

Question 11

What is the first to shut down due to lack of oxygen?

Answer 11

the electron transport chain stops first then kreb’s cycle gets backed up, glycolysis keeps going only due to fermentation
