78
Mitotic phase in
which the spindle
begins to form
79
What is prophase?
80
Pair of cylindrical
bodies in animal
cells that forms the
spindle
81
What are
centrioles?
82
Spindle fibers are
made of these
structures found in
the cytoplasm
83
What are
microtubules?
84
Spindle fibers that
attach to the
centromere of a
chromosome pair
85
What are
kinetochore fibers?
86
Spindle fibers that
extend completely
across a dividing
cell
87
What are polar
fibers?
88
Situated just outside the
plasma membrane, this
structure is composed of
glycoproteins secreted
by the cell.
89
What is the
Extracellular Matrix
90
Provide channels
between adjacent
animal cells through
which ions, sugars,
and other small
molecules can pass.
91
What are Gap
junctions?
92
Channels that
perforate adjacent
plant cell walls and
allow the passage
of some molecules
from cell to cell.
93
What are
plasmodesmata?
94
Single membrane-bound
compartments in the cell
responsible for various
metabolic functions that
involve the transfer of
hydrogen from compounds
to oxygen, producing
Hydrogen peroxide.
95
What are
peroxisomes?
96
These fibers make
up the
cytoskeleton:
97
What are
Microtubules,
Microfilaments, and
intermediate
filaments?
98
The totality of an
organism’s chemical
reactions, managing
the material and
energy resources to
the cell.
99
What is
metabolism?
100
Two pathways involved in
metabolism, one leads to the
release of energy by the
breakdown of complex
molecules to simpler
compounds. The second
pathway consumes energy to
build complicated molecules
from simpler ones.
101
What are
catabolic, and
anabolic pathways?
102
The reactant that
the enzyme acts on.
103
What is the
substrate?
104
Reversible
inhibitors tat
compete with the
substrate for the
active site on an
enzyme.
105

competitive
inhibitors?
106
The energy that is
available to perform
work when the
temperature of a
system is uniform.
107
What is free
energy?
108
Phase in which DNA
coils into
chromosomes
109

130
The process by which
ions and hydrophilic
substances diffuse
across the cell membrane
with the help of
transport proteins.
131
What facilitated
diffusion?
132
In passive diffusion, a
substance travels
from where it is more
concentrated to where
it is less concentrated
along this gradient.
133
What is the
concentration
gradient?
134
This type of
solution will cause
the cell to lose
water to its
surroundings.
135
What is
Hypertonic?
136
An ATP pump that
transports a specific
solute indirectly, and
drives the active
transport of other
substances.
137

cotransport?
138
When a cell wraps
pseudopodia around
a solid particle and
brings it into the
cell.
139
What is
phagocytosis?
140
Certain substances bind to
specific receptors on the cell’s
surface, and this causes a
vesicle to form around the
substance and then to pinch off
into the cytoplasm.
141
What is
Receptormediated
endocytosis?
142
