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.

Which 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

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…

What properties of photosynthetic pigments allow pigments to absorb light of only certain wavelengths? Select all that apply. Some pigment molecules lack a light-trapping region. Light of any energy level can boost an electron of the pigment molecule to a higher energy level in order to be absorbed. Only light with the correct wavelength to boost an electron of the pigment to a higher energy level is absorbed. All pigment molecules possess a light-trapping region with a special structure that allows electrons to move freely between its atoms.
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
