Biotechniques Exam 3

atomic number
atomic weight
composition of atoms
feedback inhibition
half life
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
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
