3.2 Cellular Respiration

Question 1

What is ATP?

Answer 1

Adenosine triphosphate is the universal carrier of energy.

Question 2

What is cellular respiration?

Answer 2

The process by which an organism breaks down energy-rich molecules (glucose) to release the energy in a usable form (ATP).

Question 3

What are the 2 types of cellular respiration?

Answer 3

• Fermentation

- Glycolysis

Question 4

What is fermentation?

Answer 4

The process of anaerobic respiration in yeasts that results in alcohol formation.

Question 5

What is glycolysis? What are its 2 types?

Answer 5

The initial breakdown of glucose into 2 three carbon molecules called pyruvate.

• Aerobic respiration
• Anaerobic respiration

Question 6

What is aerobic respiration?

Answer 6

With oxygen, where pyruvate molecules are broken down to produce carbon dioxide, water, and ATP.

Question 7

What is anaerobic respiration?

Answer 7

Without oxygen, where the pyruvate molecules pass through to prevent accumulation or build up, of pyruvate.

Question 8

Give the chemical formula for cellular respiration:

Answer 8

C6H1206 (glucose) + O2 (oxygen) = CO2 (carbon dioxide) + H2O (water) + ATP
