FUN 1 EO: 1.25

1 / 10

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

Leakage of beneficial materials

Disassociation of water

Ionization & Excitation of atoms making up the cell

Formation of free radicals

2 / 10

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

H2 + OH = H2O2

H + H = H2O2

H + OH = H2O2

OH + OH = H2O2

3 / 10

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

The cell begins to regenerate rapidly

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

The cell membrane becomes impermeable

The cell's energy reserves are depleted

4 / 10

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

Immediate rupture

Negligible effect

Increases permeability

Severe damage

5 / 10

What initiates the biological effects of radiation in cells?

Absorption of atoms

Reduction of atoms

Multiplication of atoms

Ionization of atoms

6 / 10

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

Nucleus

Cytoplasm

Mitochondria

Cell Membrane

7 / 10

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

Ionization of the nucleus

Repair of mitochondria

Rupture of the cell membrane

Formation of free radicals

8 / 10

What amount of rad is required to rupture the cell membrane?

3,000 - 5,000 rad

500 - 1,000 rad

100 - 500 rad

1,000 - 3,000 rad

9 / 10

How does radiation primarily affect the nucleus of a cell?

Causes immediate rupture of the nucleus

Increases permeability and leakage

Disrupts energy storage in the nucleus

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

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

Leads to the immediate death of the cell

Causes the cell to multiply

Repairs itself within a short time
