MCPHS BIO II EXAM SCRIPT
COMPREHENSIVE STUDY GUIDE
●● Ribosome
Answer: Made of rRNA, synthesizes proteins
●● Plasma membrane
Answer: A selectively-permeable phospholipid bilayer forming the
boundary of the cells
●● Smooth ER
Answer: Functions in detoxification and lipid synthesis
●● Hydrophobic
Answer: Water fearing
●● Rough ER
Answer: Associated with ribosomes, compartmentalizes the cell
●● Hydrophilic
Answer: water loving
, ●● Golgi complex
Answer: Corrects the folding and chemical modification of newly
synthesized proteins, packaging for protein trafficking
●● Fluid mosaic model
Answer: model that describes that cell membranes consist of a structural
framework of phospholipid molecules that is embedded with steroids
and proteins
●● Lysosome
Answer: Membrane-enclosed sac that contain hydrolytic enzymes
●● Vacuole
Answer: Storage and release of macromolecules and cellular waste
products.
●● Correct arrangement of phospholipids in bilayer
Answer: hydrophobic tails pointing toward inside the membrane,
hydrophilic heads pointing out to the extracellular or intracellular space
●● Bilayer
Answer: a layer that is two molecules thick
