Portage BioD 101 module 3with 100% correct answers
Name 4 chemical reactions associated with metabolic processes -
answer 1. Redox (Oxidation Reduction)
2. Dehydration Condensation
3. Dehydration
4. Hydrolysis
What are the 2 steps of a redox reaction? - answer 1. molecule of
the substrate loses an electron, and
2. that electron is transferred to another substrate
(Charge is reduced because you're adding a negative electron)
What is OIL RIG? - answer oxidation is loss, reduction is gain (of
electrons)
What is a dehydration condensation reaction - answer When TWO or
more monomers are joined together AND as a part of the reaction, a
molecule of water is lost AND additional, other small molecules can
be lost (eg hydrogen chloride, methanol, or acetic acid)
**REQUIRES ENERGY INPUT**
What is a dehydration reaction - answer When 2 monomers are
joined to form polysaccharides BUT the ONLY molecule lost is water
What is hydrolysis? - answer When a bio macromolecule is
DEGRADED into 2 or more monomers AND as part of the reaction a
water molecule is GAINED
**requires RELEASE of energy**
, What is metabolism? - answer The sum of all the synthetic and
degradation biochemical reactions in the human body. Can be
anabolic or catabolic.
What's the difference between catabolic and anabolic metabolism? -
answer Catabolic breaks down chemical bonds and releases. It's all
of the energy releasing degradation biochemical reactions.
Examples are digestion and cellular respiration.
Anabolic is the sum of all synthetic energy requiring biochemical
reactions energy may be required to build complex molecules, such
as proteins
Which generates more atp - aerobic or anaerobic metabolism? -
answer Aerobic
What is the basis for cellular respiration? - answer The transfer of
electrons from molecules that have stored energy, such as glucose
to other molecules. The process does not happen all at once.
What is the function of the citric acid cycle? - answer generates high
energy molecules (NADH and FADH2) that will be later used to
generate ATP in the Electron Transport Chain (ETC)
What is the difference between aerobic respiration versus anaerobic
respiration? - answer Aerobic respiration requires the use of oxygen
anaerobic does not
Describe differences between catabolism and anabolism - answer
Anabolism refers to sum of all the synthetic energy-requiring
biochemical
reactions. Catabolism refers to the sum of all the energy-releasing
degradation
