- List 5 similarities and differences between oxidative phosphorylation and light reactions in the chloroplastFor 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.Describe in detail the roles of different modes of membrane transport played in the photosynthesis in chloroplasts.
- Consider the structures and functions of mitochondria and chloroplasts. For each of the statements below, identify which part(s) of the chloroplast or mitochondrion (identified by letters in the figure below) are described. Some answers may include more than 1 letter. In those cases, separate the letters by a single space (eg. c g) Electron transport chains are located in ------ Photosystem I and II are located in ------- Ubiquinone is located in ------- NADPH is produced in ------ Pyruvate oxidation takes place in ------ ATP is produced in ------ NAD+ is produced in ----- High H+ concentration is produced in ----- O2 is produced in ----- RuBP is produced in ------In photosynthesis, contrast the light reactions with the light independent reactions, in terms of goals, inputs, and outputs of each. Spatially where do they take place (which parts of the chloroplast)? (Optional, for further discussion: Could there be light reactions without light-independent reactions, or visa-versa?)2.) A.) Explain how electron transfer leads to ATP biosynthesis in the light reactions of photosynthesis. You must give details about how electron flow builds a pH gradient and a description of the compartments in the chloroplast in relation to pH. Also, compare the ETC of the mitochondrion with the ETC of the light reactions for both the source and destination for electrons. B.) Would ATP biosynthesis happen if ionophores, which would create holes in the thylakoid membrane and allow uncontrolled passage of charged molecules such as protons between compartments, are provided to the chloroplast? Why or why not? C.) How would you modify Complex I of the electron transport chain to decrease ATP yield from Step 3 of β-oxidation? As part of this, you must explain why there is a difference in ATP yield between NADH and FADH 2 AND give a specific change to the ETC that would decrease ATP yield from Step 3
- Consider how the Hill Reaction might be used to investigate how the wavelength of light influences the rate electrons move in the electron transport chain of the chloroplast. a) Design an experiment to compare the effects of blue light and green light on the Hill Reaction. (Assume that you have filters that you can attach to your light source to control the wavelength of light.) b) Based on your knowledge of photosynthesis, how would you expect the color of the light to effect the movement of electrons? c) Draw a line graph of your expected results.The light reactions in chloroplasts power the creation of ATP via chemiosmosis. In relation to this process, which of the following is true? 1. ATP synthase breaks ATP down into ADP, creating energy to fuel chemiosmosis.2. Oxygen is used as a source of electrons to replace those lost in photosystem II.3. Chemiosmosis during the light reactions is also used in the reduction of NADPH and FADH2.4. As excited electrons fall back down to a lower energy state, they create a proton gradient that is used to fuel the phosphorylation of ADP.Identify the chemical basis for ApH and AY across the chloroplast thylakoid membrane by dragging the descriptions to their targets.

- Draw a sketch of a chloroplast and indicate where each of the following is located: CFoCF1, P700, P680, and Calvin cycle reactions. Describe the function of each.Eukaryotic chloroplasts generate exactly how many product molecules, in their consumption of six substrate carbon dioxide molecules and twelve water molecules, during oxygenic photosynthesis? twelve C6H12O6 molecules, six H2O molecules, and three CO2 molecules are produced one C6H12O6 molecule, six H2O molecules, and six O2 molecules are produced six C6H12O6 molecules, three H2O molecules, and six CO2 molecules are produced twelve H2O molecules and six O2 molecules are produced six H2O molecules and twelve CO2 molecules are producedMelvin Calvin and Andrew Benson determined the steps in the light-independent reactions of photosynthesis by exposing the green alga Chlorella to CO2 labeled with the radioisotope carbon 14. By looking at which compounds the C14 ended up in, they were able to identify all intermediates in this cyclic pathway. Why did they predict correctly that the same set of intermediates would be formed in the light reaction in land plants?
