1.3 Change to Structure of organelles

What could happen if the nuclear pores in the nucleus are damaged?

• Essential molecules like RNA may not exit properly, disrupting protein synthesis.

• Proteins may be made incorrectly or not at all.

• The cell may lose its shape and be more vulnerable to bursting.

• Light absorption and photosynthesis efficiency would decrease.

If the phospholipid bilayer of the plasma membrane loses integrity, what is a likely consequence?

• Harmful substances could enter or vital materials could leak out, upsetting homeostasis.

• Less ATP would be produced, limiting cellular energy.

• Digestive enzymes could damage the cell.

• Proteins and lipids may not be properly modified.

What is the function of the cell wall in maintaining cell structure?

• It helps the cell maintain its shape and resist bursting under osmotic pressure.

• It produces ATP for cellular energy.

• It synthesizes proteins for the cell.

• It detoxifies harmful compounds.

If the inner membrane folds (cristae) of mitochondria are reduced, what would be the result?

• Less ATP would be produced, limiting cellular energy.

• Proteins may be made incorrectly.

• The cell may lose turgor pressure and wilt.

• Light absorption would decrease.

What happens if vacuoles cannot hold water properly?

• The cell may lose turgor pressure and wilt or collapse.

• The cell may lose its ability to swim.

• Digestive enzymes could damage the cell.

• Proteins and lipids may not be shipped.

What is the consequence if ribosomes lose structural integrity?

• Proteins may be made incorrectly or not at all.

• The cell may lose its shape.

• Lipid synthesis would slow down.

• The cell may lose its ability to swim.

If ribosomes detach from the rough endoplasmic reticulum, what is the result?

• Fewer proteins would be synthesized and transported.

• The cell may lose turgor pressure.

• Light absorption would decrease.

• Digestive enzymes could damage the cell.

What would happen if the structure of the smooth endoplasmic reticulum is disrupted?

• Lipid synthesis and detoxification of harmful compounds would slow or stop.

• Proteins may be made incorrectly.

• The cell may lose its shape.

• The cell may lose its ability to swim.

If the lysosome membrane leaks, what could occur?

• Digestive enzymes could damage the cell by breaking down essential components.

• The cell may lose turgor pressure.

• Proteins and lipids may not be shipped.

• Light absorption would decrease.
