1.3 CELLULAR COMMUNICATION

Question 1

ENDOCRINE SIGNALING

Answer 1

DEPENDS ON HORMONES CARRIED IN BLOOD STREAM TO ACT ON CELLS THROUGHOUT BODY

Question 2

PARACRINE SIGNALING

Answer 2

OCCURS WHEN ENZYMES METABOLIZE CHEMICAL MEDIATORS PRODUCING A CHANGE IN NEIGHBORING CELLS

Question 3

AUTOCRINE SIGNALING

Answer 3

OCCURS WHEN CELLS RELEASE A CHEMICAL INTO EXTRACELLULAR FLUID THAT EFFECTS ACTIVITY

Question 4

SYNAPTIC SIGNALING

Answer 4

OCCURRING IN NERVOUS SYSTEM AS NEUROTRANSMITTERS THROUGH SYNAPS

Question 5

ION CHANEL LINKED RECEPTORS

Answer 5

FOUND IN NERVE CELLS AND MUSCLE CELLS

CHANLE OPENS TO ALLOW IONS TO FLOW TO NEURON

Question 6

G PROTEIN LINKED RECEPTORS

Answer 6

HAVE A LIGAND BINDING EXTRACELLULAR RECEPTOR
WHEN ACTIVE, HIGH AFFINITY FOR GTP
WHEN INACTIVE, BINDS TO GDP

Question 7

INTRACELLULAR RECEPTORS

Answer 7

ACTIVATED BY HORMONES BY MOVING ACROSS MEMBRANE
