Principles of Biology : Quiz 6 Study Guide


We will take Quiz 6 on Wednesday, Sept. 29. I recommend that you answer these questions yourself or with classmates. This not a graded assignment, nothing is to be turned in. These questions are just to help you prepare for this quiz.
Reading: You should read Chapter 4 and 5 in the text book. Also, this quiz will cover some material from Lab 5 as indicated in the questions below.

Second Version: Additional questions have been added for clarification. They are indented. Postponed questions are shown in strikethrough.

There are flashcards and animations on the Aris site you should study.   Quick Link to the Aris Site.
Also, the cell images and animations on the yellowtang site are worthwhile.  See images and  animations on yellowtang.
Also, view the Power Point presentation on membranes (see calendar).

Questions for this quiz from last week's study guide:
1) What are the components of the intermembrane system? Name them and give their function.
2) What is the cytoskeleton? What is it made of?
3) What are common extracellular structures in animals? plants?
4) What holds animals cells together?

New Questions:
5) What are the major organelles in the eukaryotic cell? What do they do? What do they look like with the transmission electron microcsope?
6) What do eukaryotic flagella basal bodies have to do with animal centrioles?
7) What are microtubules? microfilaments? Give examples of both.
8) What is the structure of membranes in biological systems? What are the typical components of these membranes?
9) What is the "fluid mosaic" model of membrane structure? What is an evidence of this?
10) What are "glycoproteins" and "glycolipids?"
11) What is  a "transmembrane domain" and what does it allow?
    11b) Here is a question where "transmembrane domain" is the answer: What is the name of the secondary level, structural element of a membrane-embedded protein that allows a comfortable existence in the hydrophobic portion of the membrane?
12) What is "diffusion?" What is passive transport?
13) What is "facilitated diffusion?"
14) What is "osmosis?"
15) What is active transport?
    15b) What is the primary energy source for active transport?
16) What is the sodium-potassium pump? How does it work?
17) What is "coupled transport?"
    17b) What is being "coupled" in "coupled transport?"
    17c) What is a "symport?" Give an example.
    17d) What is a "antiport?" Give an example.
18) What is endocytosis? what is phagocytosis? pinocytosis?
19) What is receptor-mediated endocytosis?
20) What is exocytosis?
