Lesson 4 - Aerobic and Anaerobic Respiration (Cellular Respiration)

Question 1

Where is this ATP produced
in a cell?

Answer 1

Mitochondria

Question 2

Mitochondria

• Double membrane bound ____.
• Inner membrane encloses a fluid-filled ____.
• Folded ____ project into the matrix.
  Increases surface area
• Small circular ____.

Answer 2

• organelle
• matrix
• cristae
• DNA

Question 3

Cellular Respiration Formula

Answer 3

Glucose + Oxygen –> Carbon Dioxide + Water + ATP

Question 4

There are two ways to break down food:

Answer 4

Anaerobic Cellular Respiration - Fermentation

Aerobic Cellular Respiration - just Cellular Respiration

Question 5

First process for both of the methods of Cellular Respiration

Answer 5

Glycolysis

Question 6

• occurs in the cytoplasm of cell.
• Anaerobic process

Glucose is broken down into 2 molecules
of Pyruvic Acid.

NADH is produced and carries the high
energy electrons to the ETC (last step).

Total ATP made are: 2

Answer 6

Glycolysis

Question 7

• occurs in the Mitochondria
• Process cells use to get the most energy out of food molecules.
• Aerobic process – requires oxygen
• Balanced Equation:
  6O2 + C6H12O6 –> 6CO2 + 6H2O + 36 ATP
• 2 processes: Krebs Cycle and ETC

Answer 7

Aerobic Respiration

Question 8

Location: matrix of mitochondria.

First, pyruvic acid is broken down into
Acetyl Co-enzyme A.

CO2 is produced (What happens to this?)

Electron carriers produced: FADH2 and
NADH.

Net of 2 ATP are formed. (1 from each
pyruvic acid from glycolysis)

Answer 8

Krebs Cycle

Question 9

What respiration method is done without oxygen?

Answer 9

Anaerobic Respiration Fermentation

Question 10

Anaerobic Respiration

____ ____ Fermentation – pyruvic acid is
turned into lactic acid. Bacteria produce dairy products with lactic acid.

____ Fermentation – Yeast cells
produce CO2 and ethanol.

Answer 10

• Lactic Acid Fermentation
• Alcoholic Fermentation
