BIO 201 CHAPTER ONE EXAM
QUESTIONS WITH COMPLETE
SOLUTIONS
Active tissues generate carbon dioxide, which
diffuses out the tissue into the bloodstream,
to be carried away. Is this diffusion into the
blood a case of flow up a gradient, or down?
Explain. - correct answer -
active transport - correct answer - Energy-
requiring process that moves material across
a cell membrane against a concentration
difference
adenylate cyclase - correct answer -
Activated by a G-protein. Converts ATP to
cyclic AMP in response to an extracellular
signal.
,anabolism - correct answer - Metabolic
pathways that construct molecules, requiring
energy.
appendectomy - correct answer - surgical
removal of the appendix
axoneme - correct answer - A structure
found in eukaryotic cilia and flagella and
responsible for their motion; composed of two
central microtubules surrounded by nine
doublet microtubules (9 + 2 arrangement).
cAMP - correct answer - Cyclic adenosine
monophosphate,
a ring-shaped molecule made from ATP that
is a common intracellular signaling molecule
(second messenger) in eukaryotic cells. It is
also a regulator of some bacterial operons.
,catabolism - correct answer - Metabolic
pathways that break down molecules,
releasing energy.
cell adhesion molecules - correct answer -
transmembrane proteins that bind to each
other and to extracellular materials
centriole - correct answer - structure in an
animal cell that helps to organize cell division
Centrioles - correct answer - Cell organelle
that aids in cell division in animal cells only
Cilia - correct answer - Hairlike projections
that extend from the plasma membrane and
are used for locomotion
columnar cell - correct answer - column
shaped cells
, cytoskeleton - correct answer - A network of
fibers that holds the cell together, helps the
cell to keep its shape, and aids in movement
Define adaptation & selection pressure. Why
are these concepts important in
understanding human anatomy & physiology?
- correct answer - Adaptation is a feature of
an organism's anatomy, physiology, and
behavior that has evolved in response to
selection pressures and enabled the organism
to cope with challenges of its environment.
Selection pressures are natural forces that
promote the reproductive success of certain
individuals more than others.
Define energy. - correct answer - the ability
to do work
