Step by step
Solved in 2 steps
- Photosynthesis directly opposes respiration in determining how plants influence atmospheric CO2 concentrations. When a leaf is in the light, both photosynthesis and respiration are occurring simultaneously. The data in the Table were collected from the leaf of a sagebrush plant that was enclosed in a chamber that measures the rate of CO2 exchange. The same leaf was used to collect the data in Interpret the Data in Chapter 7. Respiration is shown as a negative and photosynthesis as a positive rate of CO2 exchange. The net photosynthesis rate is the amount of CO2 (in micromoles per square meter per second) assimilated by the leaf while respiration is occurring; a positive value indicates more photosynthesis is occurring than respiration. The light exposed to the leaf is quantified as the number of photons in the 400 to 700 nm wavelength, the photosynthetic photon flux density (PPFD); 2,000 mol/m2/s is equivalent to the amount of light occurring at midday in full Sun. Observation Photosynthetic Photon Flux Density (PPFD) (mol/m2/s) Net Photosynthesis (mol/m2/s) 1 2,000 9.1 2 1,500 8.4 3 1,250 8.2 4 1,000 7.4 5 750 6.3 6 500 4.8 7 250 2.2 8 0 -2.0 Why is net photosynthesis negative when PPFD is zero? Looking at the respiration data from Interpret the Data in Chapter 7, at what temperature do you think these data were collected? Source: Data based on unpublished research by Brent Ewers, University of Wyoming.Figure 8.18 Which of the following statements is true? In photosynthesis, oxygen, carbon dioxide, ATP, and NADPH are reactants. G3P and water are products. In photosynthesis, chlorophyll, water, and carbon dioxide are reactants. G3P and oxygen are products. In photosynthesis, water, carbon dioxide, ATP, and NADPH are reactants. RuBP and oxygen are products. In photosynthesis, water and carbon dioxide are reactants. G3P and oxygen are products.Is the following statement true or false? Unlike animals, which make many ATP by aerobic respiration, plants make all of their ATP by photosynthesis.
- The Overall Free Energy Change for Photosynthetic NADP+ Reduction What is the overall free energy change (G) for noncyclic photosynthetic electron transport? 4 (700-nm photons) + 4 (680-nm photons) + 2 H2O + 2 NADP+O2 + 2 NADPH + 2H+Which of the following substances does not participate in the Calvin-Benson cycle? a. ATP c. NADPH e. PGAL b. O2 d. RuBP f. CO2During the light dependent reactions of photosynthesis, the solar energy absorbed by the chlorophyll in the photosystems is used to do what two things? pull H+ ion into a gradient in the thylakoids break apart water to replace electron in the photosystem II energize ATP synthase to make ATP for the Calvin-Benson cycle move electrons down the transport chain to NADP+ to form NADPH excite electrons to leave the chlorophyll molecules
- Which stage of the light-dependent reactions of photosynthesis is linked to photosystem I? ATP synthase phosphorylates ADP, forming ATP in the stroma. Hydrogen ions in the thylakoid compartment follow their gradient and flow through ATP synthases. Electrons from the photosystem move through an electron transport chain to form NADPH. The photosystem pulls replacement electrons from water molecules breaking the molecules into oxygen atoms and hydrogen ions.Photosynthesis is a complex process. Two main stages of photosynthesis are: H20 co 1 Light dependent reactions This step converts light energy to chemical energy. Light NADP 2 Calvin Cycle Also known as the light independent reaction. In this stage, CO2 is taken up by one of the molecules in the cycle. ATP and NADPH reduce CO2 to a carbohydrate (G3P). ADP LIGHT CALVIN REACTIONS CYCLE Thylakoid Stroma NADPH 1. Inside of the chloroplast, chlorophyll molecules absorb light and convert light energy to chemical energy. In what stage of photosynthesis is chlorophyll needed? Why? Chloroplast (CH20] (sugar) 6 CO2 + 12 H20 + light energy → CeH12O6 + 6 O2 + 6 H20 carbon dioxide + water + light energy > glucose + oxygen + water 3. What are the inputs/ reactants for Calvin cycle? 2. What are the two outputs/ products of light dependent reactions?Which of the following statements about the light reactions of photosynthesis is NOT true? Chlorophyll and other pigments absorb light energy, which excites electrons ATP is generated by photophosphorylation Electrons from water are given to the chlorophyll molecules of Photosystem! The splitting of water molecules provides a source of electrons
- Which of the following defines photorespiration? The metabolic pathway by which most autotrophs use the energy of light to make sugars from carbon dioxide and water The light-independent reactions of photosynthesis Process by which electron flow through electron transfer chains sets up a hydrogen ion gradient that drives ATP formation An inefficient metabolic pathway of producing sugars that occurs when O2 attaches to rubiscoDiagram 4: The Light Reactions of Photosynthesis STROMA (low H* concentration) Cytochrome complex Photosystem I Photosystem I Light NADP reductase 4H NADP + H NADPH THYLAKOID SPACE (high H* concentration) 4 H* Thylakoid membrane ATP synthase STROMA (low H concentration) ADP Diagram 4 shows a single thylakoid membrane taken from a chloroplast inside of a the light dependent cycle that take place along the thylakoid membrane In the Thylakoid space water is split into O 02 H* and electrons O H*, ATP and O2 O Photosystem II, electrons and oxygen O 02 and chlorophyllWhich of the following correctly sequences the steps of non-cyclic electron transport? * Water is oxidized by the capture of light energy; these excited electrons are passed through the dark reactions, returning to chlorophyll during the final light reactions The ATP and NADPH generated by the reactions of photosystem Il and photosystem I are utilized by the Calvin Cycle to build high energy glucose molecules Electrons donated from water molecules pass through photosystem I then O photosystem II before returning to the chlorophyll molecules, generating ATP in the process Chlorophyll molecules absorb UV radiation exciting electrons which flow through photosystem I, returning to the chlorophyll molecules ) This is a required question
