| Question | Answer |
|---|---|
| homeostasis | process by which organisms maintain a realtively stable interal enviorment |
| carbohydrates | compound made up of carbon, hydrogen, and oxygen atoms; major sources of energy for human body |
| lipids | macromolecule made mainly from carbon and hydrogen atoms; includes fats, oils, and waxes |
| proteins | macromolecule that contains, carbon, hydrogen, oxygen, and nitrogen; needed by the body for growth and repair and to make up enzymes |
| amino acid | compound with and amino group (-WH2) on one end and a carboxyl group (-COOH) on the other end |
| Enzymes | protein that acts as a biological catalyst |
| activation energy | energy needed to get a reaction started |
| Nucleic acids | macromolecule containing hydrogen, oxygen, nitrogen, and phosphorus |
| Nucleotide | monomer of nucleic acids made up of a 5 carbon sugar, a phosphate group, and a nitrogenous base |
| Monomer | small unit that can join together with other small units to form polyers |
| polymer | large compound formed from combinations of many monomers |
| water | H2O |
| surface tension | the result of cohesion and the measurement of the difficulty to break or stretch the surface of a liquid. |
| cohesion | means water can stick to itself H+ bonds holds molecules together (sticks to itself) |
| adhesion | H+ bonds holding molecules to another surface means water sticks to other surfaces and acts like glue. |
| Polarity | a property of water, the opposite ends have opposite charges. Hydrogen is it and oxygen is in it. Polar quality allows hydrogen bonding to occur. The polar quality also allows water to be solvent. (like dissolves like) |
| Hydrogen bonding | A hydrogen bond is the attractive interaction of a hydrogen atom with an electroative atom such as nitrogen, oxygen, or fluorine that comes from another molecule or chemical group |
| solvent | substance in which a solute is dissolved to form a solution. |
| Why are water and organic compounds important for life to exist? | Because organic compounds make up many things we need to survive. |
| What are properties of water? | -polarity -cohesion -adhesion |
| What are the properties of enzymes? | -Bind to substrate -Are specific -Has active site -Are reusable -Are effected by temp and pH. |
