CHAPTER 9 - Cellular Respiration

Question 1

In what organelle does cellular respiration take place?

Answer 1

inside the Mitochondria oxygen is needed

Question 2

Describe the process of cellular respiration?

Answer 2

The break down of food in the presence of oxygen to create ATP.

Question 3

TRUE OR FALSE: Bacteria can perform respiration. The mitochondria isn’t NEEDED for cellular respiration. Bacteria uses their outer membrane for aerobic respiration.

Answer 3

TRUE

Question 4

What are the two types of respiration and their differences?`

Answer 4

Aerobic and anaerobic respiration.
Aerobic respiration is the respiration in the presence of oxygen.
Anaerobic is the respiration

Question 5

What are the two types of respiration and their differences?`

Answer 5

Aerobic and anaerobic respiration.
Aerobic respiration is the respiration in the presence of oxygen. The complete breakdown of O2.
Anaerobic is the respiration consumes compounds other than O2

Question 6

Whats the difference between Autotrophs and Heterotrophs?

Answer 6

Autotrophs use the CO2 and H2O and converts it into organic matter. They break down the organic compound for food.

Question 7

What is the equation for cellular respiration? NOT PHOTOSYNTHESIS

Answer 7

C6H12O6 + 6O2 –> 6CO2 + 6H2O + ATP

Question 8

Label and define the parts of the mitochondria.

Answer 8

Inner and outer membrane
Any folds within the inner membrane is the CRISTAE
ATP synthase particles, granules, and ribosomes.
Everything else is known as the matrix

Question 9

What are the 3 steps of respiration?

Answer 9

Glycolysis, Kreb Cycle, and Electron Chain Trasnport.

Question 10

What are the 3 steps of respiration?

Answer 10

Glycolysis, Kreb Cycle, and Electron Chain Transport.

Question 11

Where does glycolysis occur? What is produced?

Answer 11

Cytoplasm, or the outside of the cell

2 Pyruvates, 2 ATP’s, and NADH

Question 12

What is fermentation?

Answer 12

The partial degradation of sugars without O2

Question 13

What becomes oxidized in aerobic respiraton?

Answer 13

Glucose.

Question 14

What is called the transfer of electrons in a chemical reaction between reactants?

Answer 14

Redox Reactions

Question 15

What is OIL RIG?

Answer 15

Oxidation is Loss, Reduction is Gain (Electrons)

Question 16

What are the two types of fermentation?

Answer 16

Alcoholic and Lactic Acid.

Question 17

What purpose do metabolic pathways serve?

Answer 17

They use energy sources (carbs, proteins, fats) and turn extra foods into fat for storage
- Fermentation and Aerobic respiration

Question 18

Aerobic respiration breaks down glucose into what 3 stages?

Answer 18

Glycolysis, Citric Acid Cycle, and Oxidative phosphorylation (Krebs and Electron chain)

Question 19

Describe the process of glycolysis in aerobic respiration?

Answer 19

Glycolysis occurs with or without O2, breaks down sugar into 2 pyruvates.

Question 20

When oxygen (O2) is present in the mitochondria, what does the pyruvate turn into before entering the mitochondria?

Answer 20

Acetyl CoA

Question 21

The Citric Acid Cycle is served to complete what performance?

Answer 21

The breakdown of pyruvate to CO2 as a waste product.

Question 22

Oxidative Phosphorylation is also referred to as

Answer 22

the Electron Transport Chain

Question 23

What are the two electron carriers in the electron transport chain/oxidative phosphorylation?

Answer 23

NADH and FADH2

Question 24

TRUE OR FALSE: Anaerobic respiration and fermentation allow the cell to produce ATP without oxygen (O2)

Answer 24

TRUE.

Question 25

Alcohol fermentation produces what?

Answer 25

2 Ethanol, with the release of CO2

Question 26

Lactic acid fermentation produces what?

Answer 26

2 Lactate, with no release of CO2. Happens during exercise.
