1. Warm-Up (10/1)
On the piece of white paper from the back, answer the following question.
Bacterial cell
Name
Date
Period
In terms of organelles, what is the difference between us (eukaryotes) and bacteria?
Eukaryotic cell

2. Mitochondria are the site of cellular respiration
Cristae increase surface area and contain ATP synthase
(what does that do?)

3. Chloroplasts are the site of photosynthesis
Thylakoids are membrane-bound compartments organized into stacks called grana (singular granum).

4. Chloroplasts are the site of photosynthesis
Chlorophyll is a molecule in the thylakoids which reflects green light and absorbs red and blue light.
The most common chlorophyll

5. Chloroplasts are the site of photosynthesis
Light energy is used to form ATP from ADP + P in thylakoid membrane, then ATP is used to “fix” CO2 into glucose in the stroma.

6. Light is used to form ATP in the thylakoid membrane
Energy for carbon fixation

7. Critical Thinking Question
ATP synthase is an integral membrane protein (a transmembrane protein). Explain why the structure of chloroplasts and mitochondria is important for photosynthesis and cellular respiration to take place.

8. How do organisms convert one energy source into another?
Lab Question
How do organisms convert one energy source into another?

9. Lab Question Experiments: Measuring Tools:
Cellular Respiration: mealworms fed or starved
Photosynthesis: spinach leaves w/ or w/o light
spinach leaves w/ or w/o CO2
Measuring Tools:
O2 sensor
CO2 sensor

10. Closure (10/1)
On the piece of white paper from the back, answer the following question:
Name
Date
Period
Why are plants green? Why do they change color in the autumn?
Scale 1 – 10
