Unit 4 Cell Energetics

1. What does LEO the lion says GER (or OIL RIG) stand for?

1. In photosynthesis, the NADP+ is gaining an electron. This mean the electron carrier is being:

1. In cellular respiration, pyruvate loses electrons. This means it is being:

Fill out the table below

1. If some drug were to disrupt the membranes (outer & thylakoid) of a chloroplast, explain what effect this would have on photosynthesis.

1. If some drug were to disrupt the membranes (outer & cristae/inner) of the matrix, explain what effect this would have on Cellular respiration.

1. Where does the oxygen come from in photosynthesis (be specific)?

1. What is an electron carrier? List each one you learned about AND where they are used.

1. At the end of the LIR, where is the electron that was excited from photosystem II or photosystem I?

1. Where is most of the energy stored at the end of Cellular Respiration? (take a look at the diagrams)

1. Explain how the electron transport chain (ETC) and chemiosmosis establish an electrochemical gradient across membranes.

Compare & Contrast Substrate level phosphorylation, Oxidative phosphorylation & Photophosphorylation. Fill out the table below.

1. Using the diagram below, explain how chemiosmosis is different in CR & PS. (Hint: pay attention to electrons!!!!)

1. Using the diagram above, explain how ETC & chemiosmosis are the same in CR & PS!

1. Think about the products of each step of cellular respiration Refer to the table on the first page if needed). If the cell needed to use those products to make other organic molecules, could it? Explain why or why not.

1. Describe fermentation (1pt), its products (1pt), and the conditions in which it occurs (1pt)

1. Why does yeast convert pyruvic acid during fermentation?

1. Describe the purpose of Chlorophyll & accessory Pigments.

1. Describe the connection between photosystem 1 & photosystem 2.

1. Summarize how chloroplasts convert light energy.

1. Summarize how mitochondria convert energy.

1. Draw a Venn Diagram comparing and contrasting the structure & function of chloroplast & mitochondria.

1. Using the diagram below, explain the relationship between mitochondria & chloroplasts.

1. Mitochondria convert chemical energy (found in bonds), into ______energy.

1. Chloroplasts convert ______energy into chemical energy (ATP).

1. Stomata are small openings that open and close depending in order to allow gases pass into and out of leaves. Would the number/amount of stomata that are open have an effect on photosynthesis? Explain your reasoning.

1. What factors could increase photosynthesis?

1. What factors could decrease photosynthesis?

1. What factors could increase cellular respiration?

1. How are the electrons replenished in photosystem 2? Photosystem 1?

1. What molecule captures energy released by cellular respiration?

1. List the four stages of cellular respiration in order from start to finish.

1. In Cellular respiration which process(es) are aerobic? Which are anaerobic?

Fill out the table below

Study & be able to label your diagrams!!!!
