What is a functional group?
A functional group is a specific grouping of atoms within a molecule that is responsible for the characteristic chemical reactions of that molecule.
Which of the following is an example of a functional group? A) Hydroxyl B) Carbon chain C) Amino acid
A) Hydroxyl
What are monomers?
Monomers are small, individual molecules that can join together to form larger molecules known as polymers.
True or False: Polymers are made up of multiple monomers.
True
What is the process called when monomers are linked together to form polymers?
Dehydration synthesis
Fill in the blank: Dehydration synthesis involves the removal of __________ to form a new bond.
water
What is hydrolysis?
Hydrolysis is a chemical process that breaks down polymers into monomers by the addition of water.
True or False: Hydrolysis is the reverse process of dehydration synthesis.
True
Give an example of a polymer.
Examples of polymers include proteins, nucleic acids, and polysaccharides.
What is the main difference between monomers and polymers?
Monomers are single units, while polymers are chains of monomers linked together.
Which functional group is represented by -OH?
Hydroxyl group
What type of bond is formed during dehydration synthesis?
Covalent bond
Fill in the blank: During hydrolysis, a water molecule is __________ to break a bond.
added
What is the role of enzymes in dehydration synthesis and hydrolysis?
Enzymes act as catalysts to speed up the reactions of dehydration synthesis and hydrolysis.
True or False: All functional groups are polar.
False
What are the building blocks of proteins?
Amino acids
Which functional group is involved in forming amino acids?
Amino group (-NH2)
What is a common example of hydrolysis in biology?
The digestion of food, where complex molecules are broken down into simpler molecules.
What is the significance of functional groups in organic chemistry?
Functional groups determine the chemical properties and reactivity of organic compounds.
Fill in the blank: Polysaccharides are polymers made of repeating __________.
monosaccharides
