FUN 1 EO: 1.25

1 / 10

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

Cell Membrane

Cytoplasm

Nucleus

Mitochondria

2 / 10

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

Formation of free radicals

Ionization of the nucleus

Repair of mitochondria

Rupture of the cell membrane

3 / 10

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

Severe damage

Increases permeability

Negligible effect

Immediate rupture

4 / 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

5 / 10

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

H + OH = H2O2

OH + OH = H2O2

H + H = H2O2

H2 + OH = H2O2

6 / 10

What initiates the biological effects of radiation in cells?

Multiplication of atoms

Reduction of atoms

Ionization of atoms

Absorption of atoms

7 / 10

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

100 - 500 rad

3,000 - 5,000 rad

500 - 1,000 rad

1,000 - 3,000 rad

8 / 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

9 / 10

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

Leakage of beneficial materials

Formation of free radicals

Disassociation of water

Ionization & Excitation of atoms making up the cell

10 / 10

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

The cell membrane becomes impermeable

The cell's energy reserves are depleted

The cell begins to regenerate rapidly

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