Biotechniques Exam 3
| Question | Answer |
|---|---|
| anion | |
| atomic number | |
| atomic weight | |
| cation | |
| composition of atoms | |
| compound | |
| decomposition | |
| enzyme | |
| feedback inhibition | |
| GTPase | |
| half life | |
| ion | |
| ionizing radiation | - composed of particles that individually carry enough kinetic energy to liberate an electron from an atom or molecule, ionizing it - can alter chemical bonds may change composition or structure |
| isotope | |
| kinase | |
| phosphatase | |
| proteome | |
| receptor dimerization | |
| signaling cascade | |
| 2 requirements for the storage of radioactive materials | must be secure at all time must have attending materials must be located in an unbreakable container, which is locked in a freezer or cabinet, which is located in a locked room |
| conditions for optimal enzyme function | |
| how an enzyme increases the rate of a reaction | |
| how long a permit for radioactive decay is valid | permit is valid until the conditions of the permit change |
| how signal amplification works | |
| 2 things on which chemical behaviour depends | |
| the charges of protons, neutrons, and electrons and where they are located in an atom | proton - (+) nucleus; neutron (no charge) nucleus; electron (-) |
| three types of signaling molecules | |
| two effects of ionizing radiation | can alter chemical bonds may change composition or structure |
| Five practices to reduce exposure to radiation | |
| how lysozyme me works | |
| how Ras is activated by EGF and its substrate | |
| the 3 forms of radiation and their penetration characteristics | Matter penetration a<b<g A: Too much atomic mass -> 2 pro and 2 neut to be released B: Too many neutrons in the nucleus -> a neut to be converted into a pro and elec G: Too much energy, releases a large amount of energy with no change nucleus particl |
| the 3 steps of emergency procedures in a radioactive emergency | |
| the 4 mechanisms for regulating enzyme activity | |
| three responsibilities of a radiation safety committee | 1. assign personnel monitoring devices 2. check radiation monitoring and survey instruments 3. Supervise and assist in disposal of radioactive waste 4. Report hazardous radiological conditions 5. Receive and monitor all shipments of radioactive was |
| three steps to confine radioactive contamination | |
| three things individuals using radiation must be trained in | 1. health problems related to exposure 2. precautions to minimize exposure 3. purpose and function of protective devices 4. permit conditions 5. what to do in an emergency |
| three ways to protect personnel from radiation exposure |
