BIOL 189 Exam 2 Post Lectures Questions With Complete
Solutions
A mutation in a gene would __________ cause a change in the
sequence of amino acids in a protein. Correct Answers
sometimes
A net energy yield of ______ ATP molecules per glucose are
produced during glycolysis. Correct Answers two
A single "turn" of the Krebs cycle will yield Correct Answers 1
ATP; 3 NADH; 1 FADH2
A single nucleotide deletion during DNA replication Correct
Answers Causes the amino acids encoded by nucleotides after
the deletion to be incorrect
According to the image below, a mutation in a gene is analogous
to Correct Answers A typo in a recipe
Active transport: Correct Answers This type of membrane
transport moves substances through membrane proteins and
requires energy
Arrange the following parts and processes of eukaryotic gene
expression in chronological order. Correct Answers Gene is
found
Transcription is initiated
Transcription elongation occurs
mRNA is produced
Introns are removed
, Translation occurs
Functional protein appears
Before entering the Krebs cycle, pyruvate is converted to
Correct Answers Acetyl CoA
C3 plants Correct Answers Conduct the Calvin cycle in
mesophyll cells; oxygen binds to rubisco more frequently in hot,
dry climates
C4 plants Correct Answers Fix CO2 into a four-carbon
molecule first; conduct the Calvin cycle in bundle sheath cells;
physically separate the Calvin cycle from oxygen-rich spaces in
the leaf
CAM plants Correct Answers Fix CO2 into a four carbon
molecule first; conduct the Calvin cycle in mesophyll cells; open
stomata only at night to fix CO2
Carbon reactions only: Correct Answers Uses ATP; uses
NADPH; produces glucose
Cellular respiration byproducts: Correct Answers CO2 and H2O
Cellular respiration description Correct Answers This process
uses the potential energy in organic compounds to produce ATP
Cellular respiration in the cytoplasm Correct Answers Initial
splitting of glucose; glycolysis
