PORTAGE BIOD 101 MODULE 3 EXAM
QUESTIONS WITH CORRECT ANSWERS
Chemical reactions of metabolic processes - CORRECT ANSWER-✔✔✅(1) redox reactions, (2)
dehydration condensation reactions, (3) dehydration reactions and (4) hydrolysis reactions.
Redox Reaction - CORRECT ANSWER-✔✔✅Involve transfer of electrons from a substrate which is
oxidized, to another substance which is reduced
dehydration/condensation reaction - CORRECT ANSWER-✔✔✅a reaction in which two molecules are
covalently bonded to each other through loss of a water molecule and other small molecules.
Requires energy
dehydration reaction - CORRECT ANSWER-✔✔✅A chemical reaction in which two molecules become
covalently bonded to each other with the removal of a water molecule.
hydrolysis reaction - CORRECT ANSWER-✔✔✅A biomacromolecule is degraded into 2 or more
monomers with the gain of a water molecule and release of energy
Metabolism - CORRECT ANSWER-✔✔✅The sum of all synthetic and degradation biochemical
reactions in the human body
Anabolism - CORRECT ANSWER-✔✔✅The sum total of all processes in an organism which use energy
and simple chemical building blocks to produce large chemicals and structures necessary for life.
Catabolism - CORRECT ANSWER-✔✔✅The sum total of all processes in an organism which break
down chemicals to produce energy and simple chemical building blocks.
Cellular respiration and metabolism are examples of: - CORRECT ANSWER-✔✔✅Catabolic reactions
Portage BIOD 101 Module 3 exam questions with correct answers
, cellular respiration - CORRECT ANSWER-✔✔✅Transfer of electrons that have stored energy, such as
glucose, to other molecules
aerobic respiration - CORRECT ANSWER-✔✔✅Respiration that involves consumption of oxygen.
Yields greatest amount of ATP and is primary metabolic pathway in the body.
anaerobic respiration - CORRECT ANSWER-✔✔✅Respiration that does not require oxygen
Glycolysis - CORRECT ANSWER-✔✔✅first step in releasing the energy of glucose, in which a molecule
of glucose is broken into two molecules of pyruvic acid. Can be aerobic or anaerobic; occurs in
cytoplasm
Equation for Gylcolysis - CORRECT ANSWER-✔✔✅Glucose+2NAD*+2ATP+2Pi =
2 Pyruvates+2NADH+2ADP+4ATP
Glucose - CORRECT ANSWER-✔✔✅C6H12O6
G3P - CORRECT ANSWER-✔✔✅glyceraldehyde 3-phosphate; high energy molecule used to drive
conversion of partially degraded glucose to pyruvate
Hexokinase - CORRECT ANSWER-✔✔✅converts glucose to G6P
G6P - CORRECT ANSWER-✔✔✅glucose-6-phosphate; high energy intermediate, more chemically
reactive and traps sugar inside the cell for further processing
phosphoglucoisomerase - CORRECT ANSWER-✔✔✅Converts G6P to fructose 6-P
Phosphofructokinase - CORRECT ANSWER-✔✔✅Converts Fructose-6-phosphate to fructose-1,6-
bisphosphate
Aldolase - CORRECT ANSWER-✔✔✅Converts: Fructose 1,6-Bisphosphate to Dihydroxyacetone
Phosphate (DHAP) + G3P
