| Question | Answer |
|---|---|
| biomolecules/macromolecules | large molecules that are many of many repeating subunits(monomers) that are necessary for life |
| monomer | the subunits that make larger molecules |
| polymers | macromolecules-molecules made of more than two subunits |
| carbohydrates | molecules that are made of sugars and includes sugars, starches, and fiber. Carbohydrates are made of C, H, and O atoms in a 1:2:1 ratio. |
| Monomer of carbs | sugars |
| Monosaccharide | single sugar |
| Disaccharide | double sugar |
| Polysaccharide | many sugars |
| Starches | carbs used for energy |
| Cellulose | carbs used for structure in plants |
| Chiton | carb used for structure in insects |
| 3 functions of carbs | energy, structure and cell recognition |
| Lipids | a fat molecule or a molecule that has similar properties; wax and sterols |
| 2 functions of lipids | long term energy storage, water barriers, insulate organs |
| Monomer of lipids | fatty acids and carbon chains |
| Proteins | macromolecule made of long chains of amino acids Ex. Muscles, Enzymes, hair, hooves |
| Amino acid | a compound that contains an amino acid (-NH2), a carboxyl group (-COOH), and a variable group. |
| Peptide bond | holds amino acids together to form proteins |
| Functions of proteins | movement, structures and support, and catylysts(enzymes) |
| Nucleic Acids | a long chain of nucleotides. Ex. DNA, RNA, ATP |
| Nucleotide | the monomer for nucleic acids |
| 3 Function of Nucleic Acids | Store Heredity Info. (DNA), RNA helps make protein, ATP transports immediate energy. |
| Energy | the ability to make things move or change matter. |
| Reactant(s) | a substance or substances that are involved in a chemical reaction |
| Chemical change | when one substance changes into another substance |
| Law of conservation of mass | matter cannot be created or destroyed only change form |
| Law of conservation of energy | energy cannot be created or destroyed only change form |
| Product(s) | a substance(s) that form after a chemical reaction |
| Activation energy | the amount of energy need for a chemical reaction to occur. lowered by enzymes |
| Enzyme | a molecule that increases the speed of biochemical reactions |
| Active site | part of an enzyme where the reactions take place |
| Substrate(s) | substance(s) that are either broken down or put together by enzymes |
| Catalysts | substances that speed up chemical reactions without being used up in the process |
