Biology 1510: Study
Guidelines for Lab Exam I
You will not be
able to use notes, books, or any other materials, cell phones, calculators, nor
get input from any person in the room.
The exam may contain any question that appeared in any of the
past 5 quizzes. To do well on this exam, among other things, you should read,
memorize, and understand the following:
Lipid Lab: Basic tests for lipids / Basic principles
and calculations of TLC, Rf. / What is the basic structure of lipids? / What
simple and complex procedures can be used to identify lipids? / Basic chemical structure of lipids / basic
difference between saturated and unsaturated fats
Carbohydrates
/ Nature of Science:
Goals, basic procedures, and outcomes of Benedict, Barfoed, and Iodine Tests;
for instance, why are positive reactions in the Benedict Test associated with a
change of colors? / What are the starting/ending colors of the Benedict Test? /
Predict how the following substances will respond to these 3 tests: honey,
glucose, maltose, sucrose, glycogen, amylose (taken from starch) / Experimental design: Identify hypotheses
in actual experiments and suggest
proper controls.
Amino
Acids: N-TLC test / Invariant and variable features of an amino acid: R, amine,
carboxyl groups / dehydration synthesis and hydrolysis / Basic structure of
proteins, peptide bonds
Lab
Reports: A special part of the exam, worth 8
points, will test your basic understanding of how to write a lab report and
scientific papers (pp. 117-119). For
instance, which information belongs to the Discussion section? Results section?
Microscope:
Special emphasis will be placed on the proper handling of the microscope
/ Terms of microscopy / Given the area of a field of view, determining its
radius and diameter / Basic principles
of the Cell Theory and some experimental evidence in their favor /
Prokaryots:
Shape of bacteria / logic of the gram staining protocol / basic
classification groups / your observations whether any tested bacterium is gram
negative or positive, and whether it is a coccus, a bacillus, or a spirillus.
That's about it. Good luck!
