6. Describe balloon appearance and smell
BLOW IT UP
To observe cellular respiration of yeast in an enclosed, fluid environment
Describe balloon appearance and smell
After 20 minutes

8. OMG: Gas Uptake
Q1. Describe what you observed in test tubes A and B after 24 hours.
Q2. Explain the reason behind the change in color that happened to the solution after 24 hours.

9. OMG: Gas Release
Q3. Describe what you observed in the test tube after placing it inverted on top of the funnel with Hydrilla inside?
Q4. What does the presence of bubbles represent? What is inside the bubbles?
Q5. The purpose of adding sodium bicarbonate powder is to increase the amount of carbon dioxide in the water. What is the role of carbon dioxide in the process of photosynthesis?
Q6. Discuss the exchange of gases happening during photosynthesis (discuss the uptake and release).

12. PHOTOSYNTHESIS light putting together
Putting together carbon dioxide and water, using light, to produce food and oxygen

15. Photosynthesis happens in which time of the day?
Both daytime and night time

17. In which part of the plant body does photosynthesis takes place?
Chloroplast

19. Blow it up
Q1. What happened to the balloon in the setup containing water, yeast, and sugar? How about in the setup with water and yeast only?
Q2. What do you think is inside the inflated balloon? Predict its possible identity.
Q3. Describe the smell of the resulting solution and compare it to a commercial beverage.

20. Blow it up
Q4. The experiment is an example of a cellular respiration taking place, is the setup an example of aerobic respiration or anaerobic respiration? Why do you say so?
Q5. What is/are the starting material/s of anaerobic respiration?
Q6. What is/are the end product/s of anaerobic respiration?

22. Cellular Respiration
BREATHING
RESPIRATION

23. Cellular Respiration
Breakdown of food molecule to release energy (ATP)
Can happen in the presence or absence of oxygen
AEROBIC
ANAEROBIC

24. O2 AEROBIC RESPIRATION -happens in the cytosol and the mitochondrion
-yields the greatest number of energy (ATP- adenosine triphosphate)

25. O2 ANAEROBIC RESPIRATION -also called fermentation
-happens in the cytosol
-utilizes enzymes
-yields low amount of energy (ATP)

26. O2 ANAEROBIC RESPIRATION Alcoholic Fermentation
Glucose → carbon dioxide + alcohol + energy
Lactic Acid Fermentation
Glucose → lactic acid + energy
