Portage BIOD 101 Module 3 | Questions with 100% Verified
Answers | Latest Update 2026/2027
Question: Chemical reactions of metabolic processes
Answer: (1) redox reactions, (2) dehydration condensation reactions, (3) dehydration reactions
and
(4) hydrolysis reactions.
Question: Redox Reaction
Answer: Involve transfer of electrons from a substrate which is oxidized, to another substance
which is reduced
Question: dehydration/condensation reaction
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
Question: dehydration reaction
Answer: A chemical reaction in which two molecules become covalently bonded to each other
with the removal of a water molecule.
Question: hydrolysis reaction
Answer: A biomacromolecule is degraded into 2 or more monomers with the gain of a water
molecule and release of energy
Question: Metabolism
Answer: The sum of all synthetic and degradation biochemical reactions in the human body
Question: Anabolism
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.
Question: Catabolism
Answer: The sum total of all processes in an organism which break down chemicals to produce
energy and simple chemical building blocks.
Question: Cellular respiration and metabolism are examples of:
Answer: Catabolic reactions
Question: cellular respiration
Answer: Transfer of electrons that have stored energy, such as glucose, to other molecules
, Question: aerobic respiration
Answer: Respiration that involves consumption of oxygen. Yields greatest amount of ATP and
is
primary metabolic pathway in the body.
Question: anaerobic respiration
Answer: Respiration that does not require oxygen
Question: Glycolysis
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
Question: Equation for Gylcolysis
Answer: Glucose+2NAD*+2ATP+2Pi =
2 Pyruvates+2NADH+2ADP+4ATP
Question: Glucose
Answer: C6H12O6
Question: G3P
Answer: glyceraldehyde 3-phosphate; high energy molecule used to drive conversion of
partially
degraded glucose to pyruvate
Question: Hexokinase
Answer: converts glucose to G6P
Question: G6P
Answer: glucose-6-phosphate; high energy intermediate, more chemically reactive and traps
sugar inside the cell for further processing
Question: phosphoglucoisomerase
Answer: Converts G6P to fructose 6-P
Question: Phosphofructokinase
Answer: Converts Fructose-6-phosphate to fructose-1,6-bisphosphate
Question: Aldolase
Answer: Converts: Fructose 1,6-Bisphosphate to Dihydroxyacetone Phosphate (DHAP) + G3P
