Photosynthesis Click for the RAP Bonus/AP Prep  Crash Course Photosynthesis

___ + ___+___  ___+ ___ WHAT YOU SHOULD LEARN FROM THE PHOTOSYNTHESIS RAP What are the two reactions that make up photosynthesis? ____________ Where do these two reactions occur? Which one uses the water? – What does it become? Which one uses the Carbon dioxide? What does it become?

WHERE?

PHOTO- -SYNTHESIS AKA: Light-independent Reactions

Where?

Pigments in the Process

Why do plants appear green? …

Accessory pigments – protect

Paper Chromatography Polarity, solvents…Goal = Separate Pigments. Same Dude…Chargaff's rules states that DNA from any cell of all organisms should have a 1:1 ratio (base Pair Rule) of pyrimidine and purine bases and, more specifically, that the amount of guanine is equal to cytosine and the amount of adenine is equal to thymine.

Procedure

RESULTS

Photosynthesis & Cellular Respiration They are the reverse of each other. Common Misunderstanding: Photosynthesis occurs only in plant cells, and some in Protista No it does not occur in animal cells Cellular respiration occurs in all eukaryotes! The source of the glucose is what varies. Plants – autotrophs Animals – heterotrophs Fungi – heterotrophs  Detritivores

Cellular Respiration Bonus/AP Prep  Crash Course ATP & Respiration 4 min overview Cellular Respiration Anaerobic Aerobic Cellular repiration takes place in the mitochodrion. The 3 phases of cellular respiration are Glycolysis (Fermentation), Krebs Cycle, and Electron Transport. Glycolysis takes place in the cytoplasm. The Krebs cycle and electron transport takes place in the mitochondria. Bonus/AP Prep  Crash Course ATP & Respiration

Where does Cellular Respiration Occur? Cytosol is the part of the cytoplasm that is not held by any of the organelles in the cell. On the other hand, cytoplasm is the part of the cell which is contained within the entire cell membrane.

Cellular Respiration Lab/DEMO Groups of 6: Facilitator Timer Measurer Runner!/ Test Subject Recorder CO2 + H20 > H2CO3  Bromothymol Blue (BTB)

PRELAB -- Read these paragraphs and answer the questions below

DATA Lab Trial Time 1 2 Follow-up Questions: Compare the time it took the bromothymol blue solution to change color before exercise and after exercise. Explain why there was a difference. In this investigation, we measured the amount of carbon dioxide produced to find the rate of cellular respiration. What else could we measure to find out the rate of cellular respiration?
