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

To synthesize and isolate proteins for secretion or for use in the cell
lysosome
dismantles debris
mitochondrion
energy extraction
nucleus
houses DNA
smooth ER
