AP Bio Chapter 10 Review

If photosynthesizing green algae are provided with CO2 synthesized with heavy oxygen

(18O), later analysis will show that all but one of the following compounds produced by the

algae contain the 18O label. That one is

• PGA.

• PGAL.

• glucose.

• RuBP.

• O2.

Which of the following are products of the light reactions of photosynthesis that are

utilized in the Calvin cycle?

• CO2 and glucose

• H2O and O2

• ADP, Pi, and NADP+

• electrons and H+

• ATP and NADPH

What are the products of the light reactions that are subsequently used by the Calvin cycle?

• oxygen and carbon dioxide

• carbon dioxide and RuBP

• water and carbon

• electrons and photons

• ATP and NADPH

Where does the Calvin cycle take place?

• stroma of the chloroplast

• thylakoid membrane

• cytoplasm surrounding the chloroplast

• chlorophyll molecule

• outer membrane of the chloroplast

In any ecosystem, terrestrial or aquatic, what group(s) is (are) always necessary?

• autotrophs and heterotrophs

• producers and primary consumers

• photosynthesizers

• autotrophs

• green plants

In autotrophic bacteria, where are the enzymes located that can carry on organic synthesis?

• chloroplast membranes

• nuclear membranes

• free in the cytosol

• along the outer edge of the nucleoid

• along the inner surface of the plasma membrane

When oxygen is released as a result of photosynthesis, it is a by-product of which of the

following?

• reducing NADP+

• splitting the water molecules

• chemiosmosis

• the electron transfer system of photosystem I

• the electron transfer system of photosystem II

A plant has a unique photosynthetic pigment. The leaves of this plant appear to be reddish

yellow. What wavelengths of visible light are being absorbed by this pigment?

• red and yellow

• blue and violet

• green and yellow

• blue, green, and red

• green, blue, and yellow

What wavelength of light is most effective in driving photosynthesis?

• 420 mm

• 475 mm

• 575 mm

• 625 mm

• 730 mm

Compared with the lines for chlorophyll a in the figure, where would you expect to find the

lines to differ for chlorophyll b?

• The absorption spectrum line would be lowest for chlorophyll b somewhat to the right

  of that for chlorophyll a (500—600).

• The rate of photosynthesis line for chlorophyll b would be lowest from 600—700 nm.

• The lines for the two types of chlorophyll would be almost completely opposite.

• The lines for the two types of chlorophyll would be almost completely identical.

• The peaks of the line for absorbance of b would be shifted to the left, and for rate of

  photosynthesis would be shifted to the right.
