AP Bio Unit 2 Review

Front

What type of substances can easily pass through the cell membrane?

Back

Small, hydrophobic substances can easily pass through the cell membrane due to their nonpolar nature.

Front

What is the correct pathway for the movement of a secretory protein in a eukaryotic cell?

Back

Rough ER → Golgi → secretory vesicle → Plasma Membrane.

Front

What cellular deficiency is related to mutations in mitochondrial proteins?

Back

The cell is unable to complete reactions related to electron transport and ATP production.

Front

What is a key difference between plant and animal cells?

Back

Plant cells have a central vacuole, which is not present in animal cells.

Front

What is the primary function of Rough Endoplasmic Reticulum (RER)?

Back

The production and secretion of proteins.

Front

Define hydrophobic substances in the context of cell membranes.

Back

Hydrophobic substances are nonpolar molecules that do not interact well with water, allowing them to pass through lipid bilayers easily.

Front

What role does the Golgi apparatus play in protein processing?

Back

The Golgi apparatus modifies, sorts, and packages proteins for secretion or delivery to other organelles.

Front

Explain the function of secretory vesicles.

Back

Secretory vesicles transport proteins from the Golgi apparatus to the plasma membrane for secretion.

Front

What is the function of the central vacuole in plant cells?

Back

The central vacuole stores nutrients, waste products, and helps maintain turgor pressure in plant cells.

Front

What is the significance of mitochondrial proteins?

Back

Mitochondrial proteins are essential for ATP production and energy metabolism in cells.
