A. Where are the photosystems located and what is the name of the organelle? B. Where does the energy that the photosystems take up, go? Describe for each photosystem WHERE the energy ends up at the end of the light reactions. In other words, what products contain the energy from which photosystem at the end of the light reaction?

Plant cells can perform both photosynthesis and cellular respiration. These two processes depend upon each other.  Describe in detail the relationship between carbon dioxide and glucose in plant cells. Include a description of the processes in which each is used and give the name of the organelle where each of these processes occurs.

Which of the following statements about the light reactions of photosynthesis are correct?   1. Absorption of light does one thing: it makes chlorophyll easier to oxidize. 2. In PSII, the rate of damage to the D1 protein can never exceeds the rate of repair. 3. Electron transport is spontaneous (exergonic) as electrons move from P680* to P700+. 4. Compared to anoxygenic photosynthesis, in oxygenic photosynthesis less light needs to be absorbed to reduce NADP+.   A.  1,2 and 3   B.  1 and 3   C.  2 and 4   D.  4 only   E. All of 1,2,3 and 4 are correct

Choose 2 of the following terms: Z protein / ATP synthase / Photosystem II. What is the specific role of each of the following? Describe what and how the protein does its job. As well, explain the importance of each in the overall process of photosynthesis.

Which of the following descriptions about photosystems during linear electron flow is not correct? Select one: a. energy required for ATP synthesis is provided when electrons pass through the electron transport chain from photosystem I b. photosystem II works before photosystem I c. P680 is the chlorophyll a pair that exists in photosystemII d. the primary electron acceptor receives electrons from P680 or P700 e. P680+ receives electrons from the splitting of water

IS THIS A GOOD BREAK DOWN? WHAT ELSE CAN I SHOULD I ADD?  Briefly explain the light-dependent reactions of photosynthesis: where does this take place, what are the reactants and what is produced? Light-dependent reactions are used to convert light energy into chemical energy for use by the plants. Through the process of photosynthesis, the energy collected from the sun is broken down, along with water molecules, to produce NADPH and ATP. Light-dependent reactions Goal Convert light energy into chemical energy Location Chloroplasts—thylakoids Input Sunlight, H2O, NADP+, ADP Output NADPH, ATP, O2

Part of understanding  complex metabolic processes like photosynthesis is tracking what is happening at each stage of the pathway.  As you construct this table to use as a study tool, think about what is happening in the cell and why each phase is essential for the overall function of photosynthesis.  Fill out the table below.  You may use your lecture materials, and figures from Chapter 8 of your book are especially useful for this!  Use the following terms in your table (each term may be used more than once).  For the Calvin Cycle, include the number of molecules in each stage, starting with 6 molecules of CO2. thylakoid membrane, stroma photons, H2O, O2, CO2, e-, H+, ADP, P, ATP, NADP+, NADPH G3P, RuBP, PGA, glucose   Where it occurs What goes in What comes out Light Dependent: Photosystem II + b6-f complex       Light Dependent: Photosystem I + NADP reductase + ATP synthase       Calvin Cycle: Carbon fixation       Calvin Cycle: Reduction       Calvin Cycle:…

For the following questions, choose one to discuss: chloroplast/photosynthesis State at the outset which one you will discuss.  A) What role do proton gradients play in the process of photosynthesis proton gradients allow B) Where are proton gradients formed? Within what structures are they seen in chloroplasts How do the structures help them to maintain a gradient?  C) Explain where and how the chloroplast or mitochondria uses passive transport and active transport to complete photosynthesis or cellular respiration.

Complete the following table to compare the electron-transport phase of cellular respiration with the light-dependent reactions of photosynthesis.

Which of the following processes during photosynthesis is incorrectly coupled to its typical location? Select one: a. Rubisco catalyzes carbon fixation—stroma b. ATP is produced via ATP synthase—thylakoid lumen c. NADPH is oxidized to NADP+—stroma d. Oxygen gas is produced by splitting of water—thylakoid lumen e. Activated P680 donates an electron to the primary electron acceptor—thylakoid membranes
