| Question | Answer |
|---|---|
| functional proteins | regulate chemical reactions |
| structural proteins | componet of body support tissues |
| dna | encodes hereditary info |
| rna | helps decode hereditary info acts as a rna enzyme |
| ATP | tansfer energy from fuel molecules to working molecules |
| CP/ creatine phosphate | transfers energy from fuel to ATP |
| saturated fatty acids is | one in which all available bonds of its hydrocarbon chain are filled, that is, saturates, with hydrogen bonds |
| unsaturated fatty acids is | one or more double bonds in its hydrocarbon chain because not all the chain's carbons are saturated with hrdrogen atoms |
| phospholipids are | fat compunds similar to triglycerides; they however have 3 fatty acids attached to glycerol |
| the head of a phospholipid is _____ and the tail is _______. | hydrophilic, hydrophobic |
| prostaglandins | often called tissues hormones |
| enzymes | are function proteins that bring molecules together or split them apart in chemical reactions |
| amino acids | the elements that make up a protein molecule and are bonded toegether |
| essential amino acids | they cannot be bproduced by the body and must be included in the diet |
| nonessential amino acids | can be produced from other amino acids or from simple orgaic molecules readily avalible to the body cells. |
| petide bond | is one that binds the carboxyl froup of one amino acid to the amino group of another |
| dehydration synthesesis | subunits are joined toegether, resulting in a loss of water |
| hydrolysis | requries the addition of a water molecule to break a bond |
| denature | loses it function for the protein |
| renature | brings is back to its normal function |
| denature is cause by | change in temp, change in pH, radiation and hazardous chemicals. |
| Dna molecoles | are the largest molecules in the body |
| what are the two kinds of base pair in DNA? | A-T and G-C |
| Dna is | the featuring molecule that stores the master code of all the genes needed to make the various RNA and protein molecules in the body. |
| RNA | ac ac temporary copies of the master code of hereditary info in the DNA and are involved in the process called protein synthesis |
| tRNA | is used by the cell to grap a specific amino acid and place it in the correct sequence when building a primary protein strand |
| RNA enzyme | i.e ribozyme is involved in editin gthe code of RNA strand by removing sections of the code and joining the remaining parts |
| A cell at rest a ________ concentraion, where a active cell has _______ but is constantly rebuilding its stores. | high ATP concentration, less ATP |
| an exhausted cell has ________ concentration and __________ levels of ATP. | High ADP, very low levels |
| toxins | that enter the body can cause damage to our own molecules; they comine with our molecules to render them useless, or owtherwise disrupting the normal chemcial balance and chemical activity of our bodies |
