Chlorophyll b, with a slightly different structure than chlorophyll a, has a slightly different absorption spectrum and funnels the energy from these wavelengths to chlorophyll a. Why is neither oxygen nor NADPH generated by cyclic electron flow? A difference between electron transport in photosynthesis and respiration is that in photosynthesis. What three factors contribute to the formation of this large difference in H+ concentration between the thylakoid space and the stroma? Campbell Biology Chapter 10: Photosynthesis - Practice Test Questions & Chapter Exam | Study.com. An enzyme extracts electrons from water and supplies them to the oxidized reaction center. B. photosystem I. c. water (H2O). When this compound is broken down in the bundle-sheath cells, CO2 is maintained at a high enough concentration that rubisco does not accept O2 and cause photorespiration.

A. reduces CO2 to G3P. Photoexcited electrons pass along an electron transport chain before ending up at an oxidized photosystem I reaction center. There are two types of photosystems in the thylakoid membrane. Chapter 10: photosynthesis reading guide answers.com. Water is split in the process, and O2 is released as a by-product. The light reactions regenerate ATP and NADPH. Linear electron flow along with chemiosmosis in the chloroplast results in the production of. Each chloroplast has two membranes around a central aqueous space, the stroma. Areas receiving wavelengths favorable to photosynthesis produced excess O2.

Cyclic electron flow allows the chloroplast to generate enough surplus ATP to satisfy the higher demand for ATP in the Calvin cycle. The mesophyll cells pump these four-carbon compounds into bundle-sheath cells. Chloroplasts are found mainly in mesophyll cells forming the tissues in the interior of the leaf. The Calvin cycle has three phases. Did you find this document useful? Nevertheless, the Calvin cycle in most plants occurs during daylight, because that is when the light reactions can provide the NADPH and ATP the Calvin cycle requires. 1) transport of protons into the thylakoid space as Pq transfers electrons to the cytochrome complex; (2) protons from the splitting of water remain in the thylakoid space; (3) removal of H+ in the stroma during the reduction of NADP+. Chapter 10: photosynthesis reading guide answers 2021. The following diagram is an absorption spectrum for an unknown pigment molecule. C. The cytochrome complex in the electron transport chain is not involved in cyclic electron flow.

The provider orders pulse therapy with methylprednisolone IV every 6 hours and plasmapheresis once daily. In the light reactions, light energy absorbed by chlorophyll in the thylakoids drives the transfer of electrons and hydrogen from water to NADP+ (nicotinamide adenine dinucleotide phosphate), forming NADPH. D. Chapter 10: photosynthesis reading guide answers army. adds CO2 to RuBP in the carbon fixation stage. The G3P from the Calvin cycle is the starting material for metabolic pathways that synthesize other organic compounds, including glucose and other carbohydrates. Only chlorophyll a participates directly in the light reaction, but accessory photosynthetic pigments absorb light and transfer energy to chlorophyll a. Some of the electron carriers, including the cytochromes, are very similar in chloroplasts and mitochondria. Excited electrons are unstable. You can skip questions if you would like and come.

Chapter 10: Photosynthesis Reading Guide Answers 2020

Six molecules of G3P formed from the fixation of 3 CO2 in the Calvin cycle are used to produce. All green parts of a plant have chloroplasts. An action spectrum measures changes in some measure of photosynthetic activity (for example, O2 release) as the wavelength is varied. The thylakoids convert light energy into the chemical energy of ATP and NADPH.

Chapter 10: Photosynthesis Reading Guide Answers 2021

The Calvin cycle regenerates its starting material after molecules enter and leave the cycle. The energy boost is provided by light. A. driving the splitting of water molecules. The spatial organization of chemiosmosis also differs in the two organelles. Label the indicated parts in this diagram of a chloroplast. In green plants, most of the ATP for synthesis of proteins, cytoplasmic streaming, and other cellular activities comes directly from. D. neither respiration or photosynthesis. NADPH will carry the reducing power of these high-energy electrons to the Calvin cycle.

When rubisco adds O2 to RuBP, RuBP splits into a three-carbon piece and a two-carbon piece in a process called photorespiration. CAM plants avoid photorespiration by. E. from the matrix into the stroma. A. on the diagram in Question 10. A biology student performs the photosynthesis lab procedure discussed in this lesson. A. from the stroma into the thylakoid space. Photosynthesis is a redox process in which. Autotrophs produce their organic molecules from CO2 and other inorganic raw materials obtained from the environment.
