to pass 2025/2026
What are the four classes of large biological molecules? - correct answer ✔carbohydrates
lipids
proteins
nucleic acids
Macromolecules - correct answer ✔large molecules composed of thousands of covalently connected
atoms
Polymer - correct answer ✔is a long molecule consisting of many similar building blocks
Monomers - correct answer ✔small building-block molecules
Which three of the four classes of life's organic molecules are polymers? - correct answer
✔Carbohydrates
Proteins
Nucleic acids
Dehydration Reaction - correct answer ✔occurs when two monomers bond together through the loss
of a water molecule
Hydrolysis - correct answer ✔a reaction that is essentially the reverse of the dehydration reaction
-Polymers are disassembled to monomers
, Carbohydrates - correct answer ✔include sugars and the polymers of sugars
What is the generalized formula for carbohydrates? - correct answer ✔CH2O
Monosaccharides - correct answer ✔-The simplest carbohydrates,or single sugars
-A single unit
-have molecular formulas that are usually multiples of CH2O
-serve as a major fuel for cells and as raw material for building molecules
Polysaccharides - correct answer ✔-Carbohydrate macromolecules, polymers composed of many sugar
building blocks
-have storage and structural roles
T/F: Glucose (C6H12O6) is the most common monosaccharide - correct answer ✔True
How are monosaccharides classified? - correct answer ✔-The location of the carbonyl group (as aldose
or ketose)
-The number of carbons in the carbon skeleton
Aldose and Ketose: Triosis - correct answer ✔
Disaccharide - correct answer ✔-formed when a dehydration reaction joins two monosaccharides
-2 single units
T/F: This covalent bond is called a glycosidic linkage - correct answer ✔True
