Chapter 10: Photosynthesis
This chapter is as challenging as the one you just finished on cellular respiration. However,
conceptually it will be a little easier because the concepts learned in Chapter 9—namely,
chemiosmosis and an electron transport system—will play a central role in photosynthesis.
1. As a review, define the terms autotroph and heterotroph. Keep in mind that plants have
mitochondria and chloroplasts and do both cellular respiration and photosynthesis!
Concept 10.1 Photosynthesis converts light energy to the chemical energy …show more content…
Photosystem I is referred to by the wavelength at which its reaction center best absorbs light, or
P__________; photosystem II is also known by this characteristic, or P__________. AP Biology Reading Guide Chapter 10: Photosynthesis

13. Linear electron flow is, fortunately, easier than it looks. It is an electron transport chain,
somewhat like the one we worked through in cellular respiration. While reading the section
“Linear Electron Flow,” label the diagram number by number as you read.
14. The following set of questions deal with linear electron flow:
a. What is the source of energy that requires the electron in photosystem II?
b. What compound is the source of electrons for linear electron flow? This compound is also
the source of ___________ in the atmosphere.
c. As electrons fall between photosystem I and II, the cytochrome complex uses the energy to
pump ________ ions. This builds a proton gradient that is used in chemiosmosis to produce
