BIOL 111 ramapo petro exam 1 and 2 Questions With
Complete Solutions
The term used for a permanent change in a proteins three-
dimensional shape or conformation is _____________.
denaturation
A bacterium is living in a pond where the concentration of
chlorine ions is 0.005mM. This ion is found in the bacterial
cytoplasm at a concentration of 0.10mM. Therefore the chlorine
ion is probably entering the bacterial cell by _______________
active transport
A molecule of the disaccharide maltose is formed when two
molecules of the hexose sugar glucose are chemically joined
together by a dehydration reaction. The chemical formula for
maltose is _____________
dehydration synthesis
The sulfur and oxygen is sulfur dioxide (SO2) are held together
by ____________ bonds.
polar covalent
The potassium and chlorine in KCl are held together by
_____________ bonds.
ionic
,The method ions and large polar molecules moving down their
concentration gradient across a cell membrane would need to
use is called ___________
facilitated diffusion
True or False: Assume that acid rain has lowered the pH of a
particular lake to pH 5.0. The hydrogen ion concentration of this
late is 1 x 10^5 moles/liters.
False
True or False: Peptide bonds are responsible for the primary
structure of amino acids.
True
True or False: Water rushing over Niagara Falls is an example
of potential energy.
False
True or False: Saturated fats are more common in animals than
in plants.
True
True or False: Functions of carbohydrates include structure,
defense, regulation and energy storage.
False
True or False: Catholic pathways are usually coupled with
anabolic pathways to which they supply energy in the form of
ATP.
True
, True or False: The reason areas of land located near large bodies
of water have a more moderate climate than those areas located
far from such bodies is because water has high heat of
vaporization.
False
True or False: The most abundant elements in living organisms
are carbon, hydrogen, oxygen, and phosphorus.
False
True or False: The term used to describe the structure of
biological membranes is a fluid mosaic.
True
True or False: Extremely high fevers may cause death by
breaking peptide, ionic and hydrogen bonds, which are the weak
bonds holding together the tertiary structure of proteins
responsible for their three dimensional shape and thus function.
False
True or False: One can increase the rate of a chemical reaction
of a chemical reaction by increasing the activation energy
needed.
False
An organism is described as Rr: red. The Rr is the organisms
__________________; red is the organisms
____________________; and the organism is ______________.
a. phenotype; genotype; trisomic
b. karyotype; genotype; recessive
