Monomers/ Polymers Flashcards
True or False
The variety of life in the past and present is quite little.
- No, variety of life (past and present) is extensive.
Finish sentence
The …….. ……. of ……. is similar for all living things.
- Biochemical
- Basis
- Life
DEF of monomer
- Monomers are the smaller units from which larger molecules are made.
DEF polymers?
- Polymers are molecules made from a large number of monomers
joined together.
Give 3 biological examples of monomers.
1.) Monosaccharides
2.) Amino acids
3.) Nucleotides
What does a condensation reaction do?
Diagram in school book if needed
- Joins two or more molecules (ie. monomers) together with formation of a chemical, covalent bond (to oxygen.)
- Removal of OH from one monomer’s OH and H from another monomer’s OH (elimination of water molecule.)
Monomer (OH on it) 1 + Monomer 2 (OH) —> Monomers linked by covalent bond (only O is left) + water
What does a hydrolysis reaction do?
Diagram in school book if needed
- Breaks covalent bond between two molecules (ie. monomers), involving the use/ addition of a water molecule.
Monomers linked by covalent bond + water —-> Monomer 1 + Monomer 2.
What polymers can monosaccharide monomers (ie. fructose, glucose, galactose) make?
- Polysaccharides Ie. carbohydrates.
- Glycogen
- Cellulose
- Starch
What is the covalent chemical bond type that holds together many monosaccharides to form polysaccharides?
- Glycosidic bond.
What polymers can amino acid monomers make?
- Polypeptides
- Examples: PROTEIN (hormones, collagen, enzymes, haemoglobin.)
What is the covalent chemical bond type that holds together many amino acids to form polypeptides?
- Peptide bond.
What polymers can nucleotide monomers make?
- Polynucleotides ie. nucleic acids
- EXAMPLES: DNA/ RNA
What is the covalent chemical bond type that holds together many nucleotides to form polynucleotides/ nucleic acids?
- Phosphodiester bond.
