Exam #1 Study Guide - Spring 2013
|Exam Date & Start Times:||21 February 2013
9:20AM Lab section - Exam begins at 10:00am (please arrive 5 minutes prior)
12:50PM Lab section - Exam begins at 1:00pm (please arrive 5 minutes prior)
Bring to each lab exam:
- #2 pencils,
- large eraser,
- scantron #882,
- calculator (no sharing calculators, no phones)
All other materials must be put away (i.e. in cabinets or at the front or side of the room). Scratch paper, graph paper and other materials will be provided as necessary.
The exam is worth 100 points and consists of a mix of true/false, multiple choice as well as fill-in, short answer and problem solving questions (be sure to bring a calculator!) and will cover all material from BOTH the lecture and the lab. You will have 2 hours (possibly more, if needed) to complete the exam so their should not be any time pressure. Note that once the exam begins you will not be able to leave and return (please visit the rest room prior to test time). Remember, you will be evaluated based on what you write on the test not on what you meant, so show your work and be sure your answers are clear.
How to study:
You should review all of the lecture and lab material since the start of the semester which includes the following lectures and associated labs:
|Lecture Topics:||Chpts||Lab Topics:||Manual|
|Introduction / Homeostasis||1, 6||Introduction: Homeostasis||1|
|Cell: Chemistry / Metabolism||4||Data Presentation and Analysis||3|
|Cell: Membrane Transport / Potentials||2, 3, 5||Cellular Chemistry: Enzyme Activity||4|
|Cell: Signaling||6||Membrane Transport: Diffusion & Osmosis||5|
|Cellular Metabolism: TCA||6|
Remember, both lecture and laboratory material will be covered on the exam. Use your text, lecture outlines, notes, lab materials, quizzes and assigned reading as your guide to the material you need to know.
Although you should have a clear understanding of all the material covered in all lectures and labs, the exam will be more heavily weighted towards certain topics. Be aware that the use of mathematics and graphs are an integral part of physiology and thus are likely to be an integral part of your answers. Be prepared to perform calculations and answer questions based on displayed data records (i.e. PowerLab) and to explain physiological mechanisms.
Below is a list of the major topics that are on the test and the approximate distribution of these topics (expressed as a percentage). Note: use this list with caution, the proportions are approximate. The italicized lists are intended as a general guide only - please refer back to your lecture outlines, notes, and labs for a complete review of what was covered under each of these topic categories. Remember, your primary "study guides" are the lecture outlines, lab reports and your notes.
(1) Homeostasis / Data Analysis / Graphing (~10%, but integral to other questions)
- define homeostasis and describe the mechanisms that maintain it
- interpret graphs
(2) Biomolecules (~15%)
- describe the characteristics and significance of the four primary inorganic molecules
- describe the characteristics and significance of the four primary organic molecules
- describe the different bond types and their significance
(3) Bioinstrumentation (~15%)
- describe the functions of the different components of a recording system (i.e. transducer, amplifier...)
- interpret the graphical record produced by bioinstrumentation (i.e. calculate amplitude, duration, and frequency)
- understand the reasoning behind "setting the offset" (aka "balancing") and "calibrating" bioinstrumentation prior to use
(4) Cell Chemistry: Enzymes & Metabolism (~20%)
- define and explain the terms: activation energy, exergonic, endergonic, anabolic, catabolic
- explain how the second law of thermodynamics applies to the progress of chemical reactions
- describe the basic characteristics of catalysts and more specifically, enzymes
- describe the various ways enzyme activity can be altered/regulated
(5) Membrane Transport (~30%)
- perform all calculations on the "Review Calculations - Solution Concentrations" handout
- define osmosis and diffusion and describe the principles of each
- describe the effect of different tonicity concentrations on cells
- describe the different mechanisms whereby molecules are transported across cell membranes
(6) Cell Signaling (~15%)
- define and describe the 2 principle modes of cell signalling
- describe the different mechanisms of cell reception for hydrophobic and hydrophilic signal molecules
- define and describe the primary mechanisms of hydrophilic signal transduction
Note: Exam questions will be on par with questions on quizzes, questions in the lab manual (lab activities and reports) and study guide questions associated with the lecture outlines. Suggested study tips include: reviewing your lecture notes, all of the labs and the assigned reading in the text (Silverthorn). When you have completed your review try to answer all of the lecture outline study questions and ALL of the questions in the lab manual (lab reports). Questions at the end of the chapters in the text (Silverthorn) may also be worth reviewing (caution: some of the textbook questions may emphasize concepts not pertinent to this class). If you can answer all of the questions you should be well prepared for the exam. Next, get together with a small group and review what you have learned. Rooms are available in the SM building (SM 55F - biology study room, SM 5 - math resource center), the library and in the Fox building for group study. There is a lot to learn in this class, take advantage of all the resources available to you, do all of your reading, review your notes, form a study group, and ask questions. Remember, studying is work, but I hope you are also finding physiology interesting and I hope you are enjoying what you are learning. With effort you will find that you can learn a tremendous amount! You have learned a lot already!
