Lab 2.01: Cell Structure/Subcellular Components

All eukaryotic cells contain at least one Golgi complex, typically located in the cytoplasm and near the endoplasmic reticulum. Which of the following best describes a process that occurs within the Golgi complex?

Enzymatic modification of newly synthesized integral membrane protein

Liver cells manufacture glycoproteins, while adipose cells store fat. Which of the following subcellular structures is likely to be more prominent in liver cells than in adipose cells?

Golgi apparatus

Which organelle contains hydrolytic enzymes associated with the intracellular digestion of macromolecules?

Lysosome

Prokaryotic and eukaryotic cells generally have which of the following features in common?

Ribosomes

Cells contain smaller components called organelles that are necessary for a cell's survival. Organelle functions have often been compared to components of larger systems. Which of the following functional differences between the rough and smooth endoplasmic reticulum (ER) is explained by the structural differences between them?

Rough ER can synthesize and package proteins for export, and smooth ER cannot.

Which of the following organelles modifies and packages for secretion the materials produced by the ribosomes?

The Golgi apparatus

Organelles such as mitochondria and the endoplasmic reticulum have membranes that compartmentalize reactions and other metabolic processes. To function properly, the organelles must move substances across their membranes. Which of the following statements describes a feature shared by mitochondria and the endoplasmic reticulum that increases the efficiency of their basic functions?

They have highly folded membranes

The figure below illustrates a eukaryotic cell. Which of the following best describes how the three structures (rough ER, Golgi apparatus, vesicle) indicated by the arrows work together?

To synthesize and isolate proteins for secretion or for use in the cell
