Chapter 10 Guided Reading QuestionsIntro. to 10 and 10.1: Describe how autotrophs and heterotrophs differ.Describe the structure (and maybe draw it, too) of a chloroplast.Write the photosynthesis chemical reaction and answer this: How is photosynthesis a “reverse redox” from cellular respiration?How did scientists find out that the O2 given off by plants is derived from WATER and not CO2?The first stage of photosynthesis is known as what, where does it occur, and what happens (describe all molecules involved)?How does photophosphorylation make ATP?Where does the Calvin cycle occur and how did the CO2 molecules get into the chloroplast?Explain why the Calvin cycle is sometimes called the “dark reactions” and why it is NOT an accurate nickname. What gets recycled between the light reactions and the Calvin cycle?10.2: How does light bring energy into a plant cell (use and define the words photon and pigment)?What is a spectrophotometer used for (you will be using one of these in an upcoming lab!) and what is meant by an absorption spectrum?What are some of the different pigments found in chloroplasts and what colors do they absorb and reflect?When light is absorbed by a pigment bound to the photosystem protein (aka light-harvesting complex), what happens within the photosystem (think of the electrons!)?How are PS II and PS I different (in terms of the order in which they are “used,” the pigments they use, and the light wavelengths they absorb)? Note: PS I was only named so because it was discovered before PS II.457200011811000Create a bullet-point list of the things that happen in linear electron flow (just the basics)How is cyclic electron flow different from linear electron flow?Compare and contrast chemiosmosis in cellular respiration and photosynthesis.10.3:In the Calvin cycle, carbon enters in what form and leaves in what form? For every G3P to be made, how many turns of the Calvin cycle must take place?List and describe the three phases of the Calvin cycle. IT IS NOT IMPORTANT FOR YOU TO MEMORIZE THE INTERMEDIATE ORGANIC MOLECULES, BUT IT IS IMPORTANT TO UNDERSTAND THE CONCEPTUAL SCHEME OF REDUCING CO2 TO A SUGAR.10.4: What are C3 plants (give examples) and what types of problems do C3 plants face for photosynthesis? How do they solve this problem?What are C4 plants (give examples) and what types of problems do C4 plants face for photosynthesis? How do they solve this problem?What are CAM plants (give examples) and what types of problems do CAM plants face for photosynthesis? How do they solve this problem? ................
