Why does cyanide inhibit electron transport but not photosynthesis?O In animals cyanide binding to complex IV blocks electron transport and therefore ATP synthesis, in photosynthesis thiscomplex has other hemes that cyanide cannot bind and therefore is not inhibited.O In animals cyanide binding to complex IV blocks electron transport and therefore ATP synthesis, in photosynthesis thiscomplex is not used and therefore is not inhibited.O In animals cyanide binding to complex IV prevents hydrogen gradient formation and therefore ATP synthesis, inphotosynthesis this complex is not used and therefore is not inhibited.O In animals cyanide binding to complex IV blocks electron transport and therefore ATP synthesis, in photosynthesis usesmultiple complex IVs that cyanide cannot bind and therefore is not inhibited.

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.

Looking at the respiration data from Interpret the Data in Chapter 7, at what temperature do you think these data were collected?

Is the following statement true or false? Unlike animals, which make many ATP by aerobic respiration, plants make all of their ATP by photosynthesis.
Melvin 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?
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.
Which of the following statements is/are TRUE for photosynthesis? The e- moves from H20 to NADP+. Some of the products from the dark reaction are required in the light reaction. It is an exergonic process that naturally by using energy from light It Involves conversion of 02 to H20 and C02 to glucose.
Which of the following processes during photosynthesis is incorrectly coupled to its typical location? Select one: a. Rubisco catalyzes carbon fixation—stroma b. ATP is produced via ATP synthase—thylakoid lumen c. NADPH is oxidized to NADP+—stroma d. Oxygen gas is produced by splitting of water—thylakoid lumen e. Activated P680 donates an electron to the primary electron acceptor—thylakoid membranes
Which of the following statements about photosynthesis is NOT true? Light independent reactions are very similar to the electron transport chain of cellular respiration Light is absolutely essential for both aspects of photosynthesis In order replace electrons, water is split to form oxygen gas Light dependent reactions are very similar, but in reverse, to the Krebs cycle and glycolysis
After electrons are raised to high energy levels in photosystem II, they travel down an electron transport chain. As they are stepped down in energy, the lost energy is used to power which process. The pumping of high energy electrons into the intermembrane space. This creates a large difference in concentration and in electric charge between the intermembrane space and the lumen of the thylakoid. When these high energy electrons rush back into the thylakoid lumen, they are forced to travel through one of the ATP synthase molecules that sits embedded in the thylakoid membrane. ATP synthase uses the flow of hydrogen ions to phosphorylate ADP, converting it to ATP. The pumping of hydrogen ions into the stroma. This creates a large difference in concentration and in electric charge between the stroma and the lumen (watery interior) of the thylakoid. When When the hydrogen ions in the stroma rush back into the thylakoid lumen, they are forced to…
Which of the following correctly sequences the steps of non-cyclic electron transport? a) Chlorophyll molecules absorb UV radiation exciting electrons which flow through photosystem I, returning to the chlorophyll molecules b) Electrons donated from water molecules pass through photosystem I then photosystem II before returning to the chlorophyll molecules, generating ATP in the process c) 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 d) The ATP and NADPH generated by the reactions of photosystem II and photosystem I are utilized by the Calvin Cycle to build high energy glucose molecules
Plant chloroplasts are able to generate which of the following inorganic product molecules during oxygenic photosynthesis? cell biology C6H12O6 CO CO2 O2 H2S
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.
