Study Guide for Exam 2 Chapters 3and 5
Study guide for A&PI exam #2 Fall 2010- Chapters 3 and 5- Wrinn
Chapter 3: Cells
I. Vocabulary to know from this chapter for possible matching/multiple choice questions
Hooke, Schleiden and Schwann, Virchow, plasma membrane, cytoplasm, nucleus, diffusion, membrane potential, gene, exon, intron, cell differentiation, apoptosis
II. Know these parts of the cell and their basic functions for matching or multiple choice questions:
- Membrane proteins- types: integral and peripheral
- Membrane junctions- types: tight junctions, desmosomes, gap junctions
- Cell adhesion molecules- what do they do?
- Membrane receptors- contact and chemical signaling
- Cytoplasmic organelles- what does each do? o Mitochondria o Ribosomes o Endoplasmic reticulum (ER)- rough and smooth o Golgi apparatus o Lysosomes o Cytoskeleton- microtubules, microfilaments, intermediate fibers. o Cellular extensions- flagella, cilia, microvilli o Nucleus
Which mature body cell does not have one?
What is the function of the nuclear envelope (membrane)?
What is the function of nucleoli?
What is chromatin?
- What are the three types of RNA and what is each used for?
III. What are the stages of Mitosis and what occurs at each? (this could be a potential essay question as well in which you could use diagrams to help explain). Also, what is cytokinesis?
IV. Know the differences between active vs. passive transport and how the subtypes of each work o Subtypes of passive transport- simple diffusion, facilitated diffusion- carrier mediated and channel mediated, osmosis o Be able to identify isotonic, hypertonic or hypotonic solutions and know what happens to a cell placed in each of these types of solutions. o Subtypes of active transport- primary active transport- main system = K+/Na+ pump to maintain the higher gradient of K+ inside the cell and Na+ outside the cell, secondary active transport, vesicular transport.
Types of vesicular transport: exocytosis, endocytosis,
