Which of the following represents a signaling molecule that acts long-distance?
hormone
saccharide
second messengers
neurotransmitter
Which of the following represents the correct sequence of events involved in signal transduction?
reception, response, transduction
transduction, reception, response
response, reception, transduction
reception, transduction, response
What is a molecule that specifically binds to another molecule called?
modulator
ligand
hormone
neurotransmitter
True/False: steroid hormones (non-polar/hydrophobic molecules) can passively diffuse across membranes.
True
False
What is it called when you add energy to a molecule via the addition of a phosphate
energization
phosphorylation
phosphorylase
cellular communication that occurs through cell junctions
direct contact
local signaling
long-distance signaling
signaling substances
Gap junctions
cell junction in animals cells
cell junction in plant cells
long-distance signaling
signaling substances
plasmodesmata
cell junction in animals cells
cell junction in plant cells
long-distance signaling
signaling substances
a secreting cell will release chemical messages that travel a short distance through the extracellular fluid. The chemical messages will cause a response in a target cell
local regulators
direction contact
long distance signaling
ligand
secretory cells release local regulators (ie growth factors) via exocytosis to an adjacent cell
paracrine signaling
synaptic signaling
gap junction
plasmodesmata
occurs in animal nervous systems when neurotransmitters diffuse across the synaptic cleft- space between the nerve and the target cell
paracrine signaling
synaptic signaling
gap junction
plasmodesmata
Largests category of cell surface receptors, important in animal sensory systems
GPCRs
Ion Channels
Cation Channels
CPCRs
Located in the plasma membrane, important to the nervous system, receptors act as a gate
GPCRs
Ion Channels
Cation Channels
CPCRs
