Question 1

What is the order of stages in cellular respiration?

Answer 1

1. Glycolysis
2. The Link Reaction
3. The Kreb Cycle
4. The Electron Transport Cycle (ETC)

Question 2

What are the inputs and outputs of each stage?

Answer 2

glycosis
input: glucose & ADP+P
output: ATP & Pyruvate

Kreb cycle
input: Pyruvate & ADP+P
oitput: ATP & CO2

ETC
input: O2 & ADP+P
output: ATP & H2O

Question 3

What is the location of each stage?

Answer 3

Glycosis-Cytosol
Kreb-mitochondria
etc-mitochondria

Question 4

What is the overall chemical equation for cellular respiration?

Answer 4

~29ADP+~29P—-> ~29ATP+~29PH2O

above is synthesis of ATP

C6H12O6 6O2 —-> 6CO2+6H2O

Question 5

Compare and contrast what happens in your cells to generate ATP when you have oxygen vs. no oxygen

Answer 5

In the presence of O2:
-Glycolysis-2 ATP/glucose
-Krebs Cycle-2
-ETC-~30
Total~34

In the absence of O2:
Glycolysis-2ATP/glucose
-Fermentation-0
Total=2
