BIL150 EXAM 3 QUESTIONS WITH
CORRECT ANSWERS
In the cell respiration reaction to the right which molecule (A to D) is being
decarboxylated? - Correct Answers -molecule A
In the same reaction shown on the right, what type of chemical reaction is occurring at
step 2? - Correct Answers -acylation
C-4 (Hatch-Slack) plants contain which of the following carboxylase enzymes? - Correct
Answers -both RuBP carboxylase/oxygenase & PEP carboxylase
In addition to ATP, what are the end products of glycolysis? - Correct Answers -NADH &
pyruvate
A coupled cellular reaction is one where? - Correct Answers -passive transport is
coupled with active transport
Consider the pathway below. Which molecule would commonly be referred to as the
2nd messenger? - Correct Answers -cAMP
The energy released by the transfer of electrons through the ETC is used to generate a
proton gradient in mitochondria by pumping H+ ions into which of the following cellular
locations? - Correct Answers -space between inner & outer mitochondrial membranes
Which cellular respiration metabolic pathway could be part of both the processes of
fermentation & aerobic cellular respiration? - Correct Answers -glycolysis
A NASA spaceship is designed to support animal life for a multiyear voyage. Plants will
be grown to provide oxygen & to recycle CO₂. Since the spaceship will be too far from
the sun for photosynthesis, an artificial light source will be needed. What wavelengths of
light should be used to maximize plant growth? - Correct Answers -a mixture of blue &
red light
Which of the following types of reactions would most likely decrease the entropy within
a cell? - Correct Answers -condensation reaction
