The process of photosynthesis can be modeled in various ways. For example, a chemical equation is one way to represent photosynthesis. 6CO, + 6H,0 ++ +→ 60, + C,H,,O,

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.

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:…

In photosynthesis, which of the following is NOT true about the light-dependent (“light”) reaction? In photosynthesis, which of the following is NOT true about the light-dependent (“light”) reaction? Glucose is synthesized from CO2 and water during the light-dependent reaction The light-dependent reaction converts light energy to chemical energy stored in ATP  The light-dependent reaction (non-cyclic) captures electrons in NADPH  Light-excited electrons in chlorophyll provide the energy for ATP production None of the other four answers (All are true of the light-dependent reaction)

Fill in the table below. In the first 2 columns, specify what you are comparing and contrasting in Oxidative Phosphorylation and Photosynthesis. In the second 2 columns describe in a 1-3 sentences, how they are the same and how they are different.

(c) Compare the differences between oxidative phosphorylation and photophosphorylation by redrawing (if necessary) and completing the table given below: Table 1: Comparison of oxidative phosphorylation and photophosphorylation Oxidative phosphorylation Photophosphorylation Organelle Source of electrons Final electron acceptor Source of energy Role of ATP

Based on this absorbable spectrum which of the following wavelengths are not efficient in driving photosynthesis. Please look  at picture and pick. Thanks

Extremophiles are microorganisms that can survive and proliferate in extreme environments. One group of such microorganisms are lithotrophs. These are found deep beneath the Earth's surface, living on rocks under anaerobic conditions and surviving on CO2 as their sole source of carbon. Imagine that you are studying a newly discovered lithotroph and are trying to determine what it uses as a source of electrons for reducing CO2 and for producing energy. Which one of the following conditions must be met for a molecule to serve as a useful electron donor? Oxidation of the molecule occurs with a decrease in free energy. Oxidation of the molecule occurs with an increase in free energy. Reduction of the molecule occurs with a decrease in free energy. O Reduction of the molecule occurs with an increase in free energy.

Write the overall reaction summary for photosynthesis.
