What is the name of the process that converts carbon dioxide into oxygen?
What is the name of the process that converts oxygen into carbon dioxide?
What percent of our atmosphere is oxygen? What percent is carbon dioxide?
4. When we breathe, we inhale and exhale. Explain the difference between inhalation and exhalation.

4. Anaerobic Respiration & ATP
Biology

5. ATP: Energy for the Cell
Energy is needed for all the cell’s processes including cellular respiration and photosynthesis.
ATP (adenosine triphosphate) is the organic compound that transfers energy within the cell.
ATP consists of a nitrogen base (adenine), a sugar (ribose) and three phosphate groups

6. ADP
To release the energy from ATP, the bonds between the phosphate groups must be broken.
When this occurs, only two phosphate groups are left creating ADP (adenosine diphosphate)
ADP can then be recombined with a phosphate to make ATP again.

7. Checks for Understanding
What are some key differences between ATP and ADP?
ADP- 2 phosphates
ATP- 3 phosphates

8. ATP-ADP Cycle
The continuous breaking and recombining of phosphate groups is called the ATP-ADP Cycle.
ATP is like a rechargeable battery, because it can be used over again.
ATP is the high-energy form like a charged battery.
ADP is the low-energy form like a used battery.

10. Anaerobic Respiration
A process that does NOT require oxygen is called anaerobic respiration.
Includes two processes, glycolysis and fermentation
Only 2 ATP molecules are produced through anaerobic respiration

11. Lactic Acid Fermentation
Lactic Acid fermentation- process in which an enzyme converts pyruvic acid into lactic acid
Used to manufacture foods like yogurt and cheese
Also occurs in your muscles during strenuous exercise like running

12. Alcohol Fermentation
Alcohol fermentation- process in which single-celled organisms convert pyruvic acid into ethyl alcohol
Used to produce wine, beer and bread as well

13. Checks For Understanding
What are the two processes included in anaerobic respiration?
Does anaerobic respiration require oxygen?
What are the two types of fermentation?
Glycolysis and Fermentation
No it does not
Lactic Acid and Alcohol
