IB Biology Carbohydrates Review
Practice Test.
Anabolism - CORRECT ANSWER the synthesis of complex molecules from simpler molecules, including
the formation of macromolecules from monomers by condensation reactions.
Carbohydrates - CORRECT ANSWER organic compounds with the general formula (CH2O)n, including
sugars, starches, and celluloses, that are an important source of food and energy for animals.
Catabolism - CORRECT ANSWER the breakdown of complex molecules into simpler molecules, including
the hydrolysis of macromolecules into monomers.
Disaccharide - CORRECT ANSWER sugar (carbohydrate) composed of two monosaccharides joined by
condensation.
Glucose - CORRECT ANSWER a simple monosaccharide sugar (C6H12O6) that serves as the main source
of energy and as an important metabolic substrate for most living organisms.
Monosaccharide - CORRECT ANSWER the simplest form of carbohydrate (examples include fructose,
glucose, and ribose) that constitutes the building blocks of more complex forms of sugar.
Ribose - CORRECT ANSWER a monosaccharide (chemical formula C5H10O5) found in RNA and other
metabolically important compounds.
Polarity - CORRECT ANSWER property of having distinct and opposite charges (poles).
Solubility - CORRECT ANSWER the property of a substance of being soluble (dissolved).
Solvent - CORRECT ANSWER a liquid in which substances (or solutes) are dissolved to form a solution.
