Cellular Respiration

Question 1

Where does it take place?

Answer 1

The matrix of the mitochondria (except for glycolysis)

Question 2

Glycolysis

Answer 2

Breaks glucose down into 2 pyruvate

Question 3

What comes out of glycolysis?

Answer 3

2 ATP and 2 NADH

Question 4

Citric Acid/Krebs Cycle

Answer 4

Enzymatic reaction that breaks down pyruvates

Question 5

What comes out of the Krebs Cycle?

Answer 5

1 ATP per pyruvate, NADH, and FADH

Question 6

Electron Transport Chain

Answer 6

sets up a chemical and energy gradient in the intermembrane space of mitochondria and generates ATP as protons return to the mitochondrial matrix

Question 7

What comes out of the electron transport chain?

Answer 7

25-38 ATP

Question 8

Is cellular respiration aerobic or anaerobic?

Answer 8

Aerobic

Question 9

What is the anaerobic version of cellular respiration called?

Answer 9

Fermentation

Question 10

What does fermentation lack?

Answer 10

Citric Acid Cycle and Electron Transport Chain

Question 11

What comes out of fermentation?

Answer 11

2 ATP per glucose molecule

Question 12

What are the disadvantages of fermentation?

Answer 12

• causes a lactic acid build-up in cells
• in yeast, it produces ethyl alcohol and CO2 instead of lactate
