302 Macrmo Functions
Term | Definition |
---|---|
organic compounds - | Compounds that contain carbon they are what living things are made of |
compounds - | 2 or more elements chemically combined |
the four macromolecules - | carbohydrates, lipids, proteins, nucleic acids the molecules living things are made of |
carbon - | an element found in all living things can form four bonds, which is a lot |
macro- - | big Opposite of micro- |
molecule - | A group of atoms bonded together |
monomers - | building blocks of polymers |
polymers - | chains of monomers |
carbohydrates - | starches and sugars monomer: monosaccharides polymer: polysaccharides |
function of carbohydrates - | main source of energy for cells Used for short-term energy storage broken down to make ATP |
lipids - | fats, oils, cholesterol, and wax they do not mix with water monomers: glycerol and fatty acids polymer: triglycerides |
functions of lipids - | Insulation Long-term energy storage Used to form cell membranes |
proteins - | monomer: amino acids polymers: proteins, AKA polypeptides |
functions of proteins - | many functions include: speeding up chemical reactions, structural support, forming channels in cell membranes that regulate movement across the cell membrane |
enzymes - | a type of protein they speed up chemical reactions |
Nucleic acids - | DNA and RNA monomers: nucleotides polymers: DNA and RNA |
function of nucleic acids - | store and transmit genetic information |
transmit - | to carry information example: messenger RNA transmits genetic information from the nucleus to ribosomes in the cytoplasm |
genetic information - | A set of instructions coded in DNA molecules that specifies the traits of an organism example: eye color |
breaking molecules down - | catabolism hydrolysis occur during digestion |
building molecules - | anabolism dehydration synthesis example: when cells combine amino acids to build proteins |
Carbohydrate names - | Often end in -ose |
composed of - | made of |
Atoms - | Building blocks of matter |
Molecules - | two or more atoms bonded together |
