In Olfactory Receptor Cells,signal Transduction Cascades Often Follow This Order

question 58

Multiple Choice

In olfactory receptor cells,signal transduction cascades often follow this order:

• A)receptor binding → G-protein activation → cAMP → cell depolarization
• B)cell depolarization → increased intracellular Ca²⁺ → adenylate cyclase activation
• C)receptor binding → opening ion channels → G protein activation → cell depolatization
• D)cell depolarization → adenylate cyclase → G-protein activation → conformational change
