Step by step
Solved in 2 steps
- Explain the reciprocal nature of the net chemical reactions for photosynthesis and respiration.Is the following statement true or false? Unlike animals, which make many ATP by aerobic respiration, plants make all of their ATP by photosynthesis.What two products result from photosynthesis? a. water and carbon dioxide b. water and oxygen c. glucose and oxygen d. glucose and carbon dioxide
- To reduce six molecules of carbon dioxide to glucose via photosynthesis, how many molecules of NADPH and ATP are required? a. 6 NADPH and 6 ATP b. 12 NADPH and 12 ATP c. 12 NADPH and 18 ATP d. 18 NADPH and 12 ATP e. 24 NADPH and 18 ATPUsing the graph comparing photosynthetic rate and absorption of different wavelengths of light, what can be concluded? a) The photosynthesis rate at 550 nm is the highest b) Chlorophyll a absorbs wavelengths at both ends of the spectrum c) Chlorophyll b is associated with the greatest rate of photosynthesis. d) Carotenoids absorb the narrowest range of wavelengths of lightWe are measuring oxygen production assuming it corresponds to the rate of photosynthesis. Do you think this is a correct assumption? Why or why not?
- Compare and contrast photosynthesis and cellular respiration (how are they the same, and how are they different). Why are the processes like two sides of the same coin?Compare and describe the roles of CO2 and H2O in cellular respiration and photosynthesisWhat is the difference between photosynthesis rate and net photosynthesis rate?
- In 1941, biologists exposed photosynthesizing cells to water containing a heavy oxygen isotope, designated 180. The "labelled" isotope appears in the 02 gas released in photosynthesis, showing that the oxygen came from water. Where would the 180 have ended up if the researcher had used 180-labeled CO2 instead of H2O? A. ADP B. NADP+ C. Rubisco D. DP and NADP+ E. GlucosePropose a hypothesis on how each of these variables affects the production of oxygen from a plant. 1. Increasing light intensity 2.Increasing CO2 levels 3.Increasing temperature 4.How does light intensity affect the rate of photosynthesis?When discussing the graph, the narrator describes a point at which the rate of photosynthesis levels off and mentions factors that might have prevented further increases in the rate of photosynthesis. What are the correct terms for this point and these factors? Select one or more: a. saturation point, limiting factors b. saturation point, restricting factors c. plateau point, restricting factors d. plateau point, limiting factors
