-Which of the nitrogenous bases is part of DNA, but not RNA? - -thymine
-Which phase of mitotic cell division is represented by this picture? - -prophase
-A DNA strand with a base sequence of ACTTCGCATG, when replicated, would yield a
newly formed strand of the same base sequence. - -false
-Which of the following would NOT be an example of an enzyme? - -A molecule that
helps to form the cytoskeleton of a cell
-Lipids - -contain C, H, and O, but with proportionately less oxygen than in
carbohydrates.
are insoluble in water.
include phospholipids, cholesterol, and fats.
-A water solution that contains equal numbers of hydrogen ions and hydroxide ions is -
-neutral
-Glycogen is stored in the liver and __________. - -skeletal muscles
-The origin of the term "anatomy" is related to - -the Greek word for "cutting up."
-DNA - -stores genetic information, including instructions for enzymes that synthesize
fats and carbohydrates
-A cell may contain hundreds of different types of enzymes. - -true
-The atomic weight of an element whose atoms contain 8 protons, 8 electrons, and 8
neutrons is - -16
-Consider the following list of commonly found items and their pH values:
, Baking Soda (8.3), Battery Acid (1.0), Beer (4.2), Bleach (12.8), Butter (6.1-6.4), Coffee
(5.0), Egg Whites (7.6-8.0), Grapes (3.5-4.5), Milk of Magnesia (10.6), Tomato (4.0-4.5),
Vinegar (2.2), White Bread (5.0-6.0)
Which of the following choices includes all acids? - -Vinegar, grapes, tomatoes, and
coffee
-The framework of a cell membrane is a lipid bilayer. - -true
-Endoplasmic reticulum is best described as a - -network of interconnected
membranes.
-Which organelle contains the nucleolus? - -nucleus
-The type of organic molecule that can replicate is a - -nucleic acid
-A patient's blood test shows that their blood pH is 7.29. They are most likely
experiencing - -acidosis
-An electrolyte ionizes in water. - -true
-The molecule shown is a(n) __________ molecule. It is a type of __________. - -
triglyceride; lipid
-Which of the following would be considered an element? - -oxygen
-When placed into water, the ionic compound NaCl will - -dissociate into Na+ and Cl-
ions.
-The parietal pleura is a visceral membrane. - -false
-Loss of cell cycle control can cause cancer. - -true
-The basic steps of an enzyme-catalyzed reaction are - -substrate and enzyme combine,
forming an E-S complex. The reaction occurs, products are released, and the unchanged
enzyme is released and recycled.
-What is a cofactor? - -Nonprotein molecule that must combine with some enzymes in
order for them to become active
