Two main steps in redox reactions .....Answer.....Oxidation

(electron is lost from a substrate) and Lost electron transferred to

another substrate (OILRIG: Oxidation is loss, reduction is gain (of

electrons))


Dehydration condensation reaction .....Answer.....2+ monomers

are joined TOGETHER and a water molecule is LOST. Requires

an INPUT of energy


Dehydration Reaction .....Answer.....Joins monomers to form

polysaccharides and the ONLY molecule lost is water

,age 2 of 23




Hydrolysis reaction .....Answer.....Biomacromolecule is DEGRADED

into 2+ monomers and a water molecule is GAINED. Results in a

RELEASE of energy


Metabolism .....Answer.....sum of all synthetic energy and

degradation biochemical reactions in the body


Anabolism .....Answer.....sum of all synthetic energy-requiring

biochemical reactions


Catabolism .....Answer.....sum of all energy-releasing

degradation biochemical reactions


Respiration .....Answer.....Transfer of electrons from molecules

that have stored energy to other molecules

, age 3 of 23




Aerobic respiration .....Answer.....respiration involving

consumption of oxygen. yields most ATP and is the primary

metabolic process in the human body


Anaerobic respiration .....Answer.....respiration that can proceed

in the absence of oxygen


Three distinct processes of cellular respiration

.....Answer.....Glycosis, citric acid cycle (CAC), and electron

transport chain (ETC)


Where does Glycosis occur .....Answer.....cytoplasm


Where do CAC and ETC occur .....Answer.....mitochondria


Two main phases of glycosis .....Answer.....Energy investment

phase and energy payoff phase
