Cytoplasm Nucleus Cell Membrane Mitochondria 2 / 10 How does hydrogen peroxide (H2O2) form as a secondary effect of radiation? H2 + OH = H2O2 OH + OH = H2O2 H + OH = H2O2 H + H = H2O2 3 / 10 What amount of rad is required to rupture the cell membrane? 500 - 1,000 rad 100 - 500 rad 1,000 - 3,000 rad 3,000 - 5,000 rad 4 / 10 What happens when mitochondria are exposed to "a few thousand" rad of radiation? Repairs itself within a short time Disrupts the function and interrupts the storage of energy via ATP Causes the cell to multiply Leads to the immediate death of the cell 5 / 10 How does radiation primarily affect the nucleus of a cell? Disrupts energy storage in the nucleus Inhibits the ability of the cell to divide by affecting the DNA and RNA Causes immediate rupture of the nucleus Increases permeability and leakage 6 / 10 What initiates the biological effects of radiation in cells? Absorption of atoms Ionization of atoms Multiplication of atoms Reduction of atoms 7 / 10 What does the primary effect of radiation in a cell consist of? Ionization & Excitation of atoms making up the cell Leakage of beneficial materials Disassociation of water Formation of free radicals 8 / 10 What is one of the secondary effects of radiation interaction in a cell? Ionization of the nucleus Rupture of the cell membrane Formation of free radicals Repair of mitochondria 9 / 10 What occurs when lysosome ruptures between 500 and 1,000 rad (5 - 10 gray)? The cell membrane becomes impermeable Digestive enzymes are released and begin to digest the rest of the cell The cell begins to regenerate rapidly The cell's energy reserves are depleted 10 / 10 What is the result of ionizing radiation hitting the cytoplasm of a cell? Increases permeability Negligible effect Severe damage Immediate rupture Your score is Share your results with your friends!!
