BIL 151 Lab section K1/U4 Name:_________________________________________ Quiz 10 (optional—if you take this quiz, you can drop your two lowest quiz grades instead of your one lowest) 1) Where in the chloroplast do the light-dependent reactions of photosynthesis occur? Thylakoid membranes 2) What is the job of the primary electron acceptor in photosystems I and II? It accepts the excited electron from the chlorophyll a or b in the reaction center of PS I and II, elevating its energy. The electron acceptor in PS II sends it down the electron transport chain to produce ATP and to go into PS I. The electron acceptor in PS I transfers it to ferredoxin, after which NADP reductase uses it to catalyze the reduction of NAPD + to NADPH 3) Would indophenol change from blue to colorless over time if you added it to the photosynthetic pigments you extracted in lab 7? Why or why not? The answer to this might go either way because there’s not a lot of detail in the lab manual

Unformatted text preview: about what the photosynthetic pigments are actually capable of on their own and where exactly the indophenol blue accepts electrons from. What I looked for here was not whether you said yes or no, but whether your explanation made sense, given what we know. True or False: If the answer is false, correct the phrase to make it true 4) T F The oxygen produced by photosynthesis comes from the carbon dioxide water taken in by the plant Choose the one best answer 5) Hills experiment showed that combining water and iron salts with isolated chloroplasts creates oxygen when exposed to light. What does this demonstrate? a. Chloroplasts are able to undergo photosynthesis only in living plants b. NADP+ is not necessary for photosynthesis to occur in living plants c. Most of the photosynthesis process can take place in isolated chloroplasts d. Only a small portion of the photosynthesis process can take place in isolated chloroplasts...
