BIO 360: ANIMAL PHYSIOLOGY EXAM 1
QUESTIONS WITH VERIFIED
SOLUTIONS
Which of the following processes occurs in the photoreceptor cell of the eye
when a photoreceptor senses light? - correct-answer - the membrane
hyperpolarizes (becomes more negative)
Choose the true statement about cellular energetics and metabolism - correct-
answer - Both glycolysis and the Krebs cycle require NAD
Select the mechanisms by which an animal can increase the activity (rate of use)
of an enzyme protein. - correct-answer - allosteric modulation of the enzyme
, 2
Choose the TRUE statement about energy and fuel use. - correct-answer -
glycogen can be catabolized with or without oxygen
Choose the true statements about the peripheral nervous system: - correct-
answer - Nicotine binds to receptors at the preganglionic synapse for both the
sympathetic and parasympathetic nervous system
Choose the true statements about sensory neurons (choose all that are correct): -
correct-answer - sensations on the left side of the body map to the right side of
the brain
stronger sensations usually are associated with higher frequencies of action
potentials in the sensory neuron
What are some normal consequences of activation of the parasympathetic
nervous system (choose all that are correct) - correct-answer - stimulation of the
digestive system
, 3
lowering of heart rate
Which process would usually produce a graded depolarization in a neuron? -
correct-answer - opening of a Na+ channel
A strong stimulus is sensed by the brain as larger magnitude action potentials. -
correct-answer - False
A finer sense of discrimination usually is made possible by having larger receptor
cells - correct-answer - False
Transient Receptor Potential proteins respond to ___________. - correct-answer -
temperature and chemicals
