BIOL-2421 Microbiology Exam
|Questions with 100% Solutions/Verified
Answers
Allosteric enzymes - ANSWER have an additional binding site that is involved in
regulating enzyme activity
The name given to the reaction involving removal of electrons or hydrogen atoms
from a compound is - ANSWER oxidation
The sugar component of RNA and DNA nucleotides is synthesized - ANSWER as
ribose and then changed to deoxyribose
The readily usable energy currency of cells is - ANSWER ATP
Biosynthetic reactions that require energy for the conversion of molecular subunits
into larger molecules are called - ANSWER anabolic reactions
The transition step - ANSWER links glycolysis to the TCA cycle
Which is true regarding the three central metabolic pathways?
- They form high-energy bonds that can be used to synthesize ATP.
-They form intermediates that can be oxidized to generate reducing power.
, -They form precursor metabolites.
- All of the answer choices are correct. - ANSWER - All of the answer choices are correct.
Why would a cell ferment rather than respire? - ANSWER There is no oxygen present
and it cannot use anaerobic respiration OR it lacks the ability to respire (i.e., no
electron transport chain)
Chapter 7 Quiz - ANSWER The Blueprint of life, from DNA to Protein
The molecules that bind to a repressor and cause it to no longer bind to the
operator are called - ANSWER inducers
Ribozymes are non-protein molecules with catalytic activity.
True or False - ANSWER True
Which is FALSE about the RNA transcript?
- It is formed using the DNA minus strand as a template.
- It has the same 5'-3' orientation as the DNA positive strand.
- It is made in short fragments that are then stitched together.
