Concept explainers

Photosynthesis

Plants have a capacity that we humans can only imagine— the ability to produce food from sunlight. Sure, we can prepare some dishes that we can savor on, but it become possible because of the plants (as they serve as a producers of all the raw materials required). Photosynthesis is the method of assembling carbohydrates with the aid of sunlight.

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 Source: Data based on unpublished research by Brent Ewers, University of Wyoming.

As electrons move through the electron transport chain of photosystem II, they lose en- ergy. What happens to this energy? A B с D It is used to establish and maintain a proton gradient. It is used to produce NADPH, which accepts electrons from photosystem I. It excites the electrons in photosystem I. The energy is transferred to unusable heat energy and is lost by the system.
The figure shows the absorption spectrum for chlorophyll a and the action spectrum for photosynthesis. Why are they different? 400 500 600 700 Wavelength of light (nm) O Green and yellow wavelengths inhibit the absorption of red and blue wavelengths.

During 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
