Cell Respiration

Question 1

Clicker:
C6H12O6 + 6O2 -> 6CO2 + 6H2O + ENERGY (ATP & heat)

The reaction above is an example of:
A. Catabolic Reaction
B. Anabolic Reaction

Answer 1

a.) Catabolic Rxn

Question 2

4 Stages of Carbohydrate Energy Harvest?

Answer 2

1.) Glycolysis
2.) Pyruvate Oxidation
3.) Citric Acid Cycle (Krebs Cycle)
4.) Oxidative phosphorylation (Electron Transport Chain)

Question 3

Reducing Agents of Cell Respiration?

Answer 3

NADH and FADH2
electron carriers that link all stages of cellular respiration

Question 4

Glycolysis
What are its two stages?

Where does Glycolysis occur?

Answer 4

1.) Energy Investment Reactions
2.) Energy Harvesting Reactions

Cytosol (cell liquid)

Question 5

Input of Glycolysis? (Energy Investment)

Answer 5

2 ATP per glucose molecule

Question 6

Output of Glycolysis?

Answer 6

4 ATP, 2 NADH

Question 7

1.) Where does Glycolysis and Fermentation occur?
2.) Where does the rest of cell respiration occur?

Answer 7

1.) Cytosol
2.) mitochondria

Question 8

Structures of mitochondria? (2)

Answer 8

1.) inner and outer membranes
2.) Matrix and Cristae
-cristae increases membrane surface area

Question 9

Pyruvate Oxidation

Answer 9

pyruvate is further oxidized by Co-A producing Acetyl Co-A

Occurs in the mitochondrial matrix

Question 10

Citric Acid Cycle (Krebs)

Answer 10

releases energy from nutrients through the oxidation of acetyl Co-A

-Substrate level phosphorylation
