d.aerobicand anaerobicUnderstanding Key Ideas
6.Energy flows through living systems
from?
a.the sun, to heterotrophs, and
then to autotrophs.
b.autotrophs, to the environment, and
then to heterotrophs.
c.the sun, to autotrophs, and then to
heterotrophs.
d.the environment, to heterotrophs, and
then to autotrophs.
7.The products of photosynthesis that begin
cellular respiration are
a.organic compounds and oxygen.
b.carbon dioxide and water.
c.NADP+and hydrogen.
d.ATP and water.8.The thylakoid membranes of a chloroplast
are the sites where
a.electron transport chains operate.
b.NADPH and ATP are produced.
c.pigments are located.
d.all of the above
9.The oxygen produced during photo-
synthesis comes directly from the
a.splitting of carbon dioxide molecules.
b.splitting of water molecules.
c.mitochondrial membranes.
d.absorption of light.
10.Which of the following is the correct pairing
of a process and its requirement for oxygen?
a.glycolysis: no oxygen required
b.fermentation: oxygen required
c.Krebs cycle: no oxygen required
d.none of the above
11.Study the micrograph of a chloroplast shown
below, and identify the structures labeled X.
During photosynthesis, are hydrogen ions
more concentrated in these structures or in
the spaces around them?12.Analyze the flow of energy that enables you to
get energy from the food you eat.- What change occurs in
muscles at the anaerobic threshold?
14.How is starch broken down to glucose
prior to glycolysis? (Hint:See Chapter 2,
Section 4.) - Concept MappingMake a concept
map that shows how photosynthesis and cel-
lular respiration are related. Try to include
the following terms in your map: glycolysis,
Krebs cycle, electron transport chain, Calvin
cycle, fermentation,and NADH.
