Plasma Membrane and Endomembrane System

Front

What are lysosomes?

Back

Lysosomes are vesicles from the Golgi apparatus that contain digestive enzymes to break down food, cellular debris, and foreign invaders like bacteria.

Front

Identify the organelle responsible for energy production in cells.

Back

Mitochondria are the organelles responsible for producing energy (ATP) through cellular respiration.

Front

What is NOT a function of the endomembrane system?

Back

Creation of ATP (energy) is NOT a function of the endomembrane system.

Front

What component of the plasma membrane helps to minimize the effects of temperature on fluidity?

Back

Cholesterol helps to minimize the effects of temperature on the fluidity of the plasma membrane.

Front

How does the saturation of fats affect membrane rigidity?

Back

The more saturated fat is in a membrane, the more rigid it is.

Front

What is the primary function of the plasma membrane?

Back

The primary function of the plasma membrane is to protect the cell and regulate what enters and exits.

Front

Define the endomembrane system.

Back

The endomembrane system is a group of membranes and organelles in eukaryotic cells that work together to modify, package, and transport lipids and proteins.

Front

What role do ribosomes play in the cell?

Back

Ribosomes are responsible for protein synthesis in the cell.

Front

What is the function of the Golgi apparatus?

Back

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

Front

What is the structure of the plasma membrane?

Back

The plasma membrane is primarily composed of a phospholipid bilayer with embedded proteins, cholesterol, and carbohydrates.
