BIO 152 EXAM RETAKE WITH
CORRECT ANSWERS 2025
What does an integrator do in a homeostatic feedback loop?
correct answers >> Compares the stimulus value to a set point
Homeostasis typically relies on negative feedback because
positive feedback correct answers >> Drives a process to
completion rather than to a balance point
What is the effector when blood sugar gets too high? correct
answers >> The liver, muscles, and fat cells
All cell to cell communication pathways require correct
answers >> A signal and receptor
Advantage to multiple types of receptors for the same ligand
correct answers >> Different receptors allow different cell types
to respond to the same ligand in different ways
Receptor kinases gain what when they are active correct
answers >> Phosphate groups
What would cause the opening of a ligand gated potassium ion
channel? correct answers >> A neurotransmitter binding to
the receptor
, Repose to G protein couple receptor changing ligand shape
correct answers >> Transduction
I travel lunar signaling cascades when correct answers >> A
phosphatase removes the phosphate groups from activated
proteins
What type of protein is ASK1? correct answers >> Kinase
Nervous system in jellyfish correct answers >> Neurons that
are connected by a network without a central nervous system
