FUN 1 EO: 1.25

1 / 10

How does radiation primarily affect the nucleus of a cell?

Increases permeability and leakage

Inhibits the ability of the cell to divide by affecting the DNA and RNA

Causes immediate rupture of the nucleus

Disrupts energy storage in the nucleus

2 / 10

What initiates the biological effects of radiation in cells?

Absorption of atoms

Multiplication of atoms

Reduction of atoms

Ionization of atoms

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

How does hydrogen peroxide (H2O2) form as a secondary effect of radiation?

H2 + OH = H2O2

OH + OH = H2O2

H + OH = H2O2

H + H = H2O2

5 / 10

What is the result of ionizing radiation hitting the cytoplasm of a cell?

Immediate rupture

Increases permeability

Negligible effect

Severe damage

6 / 10

What part of the cell is often likened to the brain?

Nucleus

Cell Membrane

Mitochondria

Cytoplasm

7 / 10

What occurs when lysosome ruptures between 500 and 1,000 rad (5 - 10 gray)?

The cell begins to regenerate rapidly

The cell's energy reserves are depleted

Digestive enzymes are released and begin to digest the rest of the cell

The cell membrane becomes impermeable

8 / 10

What is one of the secondary effects of radiation interaction in a cell?

Formation of free radicals

Ionization of the nucleus

Rupture of the cell membrane

Repair of mitochondria

9 / 10

What does the primary effect of radiation in a cell consist of?

Disassociation of water

Ionization & Excitation of atoms making up the cell

Formation of free radicals

Leakage of beneficial materials

10 / 10

What happens when mitochondria are exposed to "a few thousand" rad of radiation?

Disrupts the function and interrupts the storage of energy via ATP

Causes the cell to multiply

Leads to the immediate death of the cell

Repairs itself within a short time
