Biology Flashcards
What are monomers
Smaller units which can create larger molecules
What are polymers
Lots of monomers bonded together
What polymers can monomer glucose create
Starch
Cellulose
Glycogen
What polymers can monomer amino acid create
Protein
What polymers can monomer nucleotide create
DNA
RNA
What is a condensation reaction
Joining two molecules creating a chemical bond and removing water
What is hydrolysis reaction
Breaking a chemical bond between two molecules and involves the use of water
What are monosaccharides, dissaccharides and polyccharides
Monosaccharides one sugar unit
Dissaccharides two sugar units
Polyccharides many sugar units
What are some of the monosaccharides
What are some of the dissaccharides
What are some of the polyccharides
Monosaccharides - glucose fructose galactose
Dissaccharides - sucrose maltose lactose
Polyccharides - starch cellulose glycogen
What are disaccharides joined by
Glycosidic bond
Condensation reactions fir disccharides
glucose + glucose -> maltose + water
glucose + galactose -> lactose + water
glucose + fructose -> sucrose + water
Where is starch found and what is it used for
Plants
Store of glucose
Where is cellulose found and what is it used for
Plants
Structural strength, in the cell wall
Where is glycogen found and what is it used for
Animals
Store of glucose, mainly liver and muscle cells
