Front

What is the function of the rough endoplasmic reticulum (ER)?

Back

The rough ER is primarily involved in the synthesis of proteins due to the presence of ribosomes on its surface.

Front

What process do proteins made in the rough ER undergo to be secreted from the cell?

Back

Proteins made in the rough ER are secreted by exocytosis.

Front

Which type of molecules can easily cross the cell membrane without assistance?

Back

Small, nonpolar molecules can easily cross the cell membrane unassisted.

Front

Where are proteins synthesized for export via exocytosis?

Back

Proteins for export are synthesized in the rough endoplasmic reticulum (ER).

Front

What is a hypertonic solution?

Back

A hypertonic solution has a higher solute concentration compared to another solution.

Front

What is the role of the Golgi apparatus in protein processing?

Back

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

Front

Define osmosis.

Back

Osmosis is the movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What is diffusion?

Back

Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is water potential?

Back

Water potential is the potential energy of water in a system, influencing the direction of water movement.

Front

What is the difference between isotonic, hypertonic, and hypotonic solutions?

Back

Isotonic solutions have equal solute concentrations, hypertonic solutions have higher solute concentrations, and hypotonic solutions have lower solute concentrations.
