What is the primary mechanism for transducing signals into the intracellular signaling path?
What is the primary mechanism for transducing signals into the intracellular signaling path?
- Binding of molecules/ligands to cell surface receptors (correct)
- Activation of cytoplasmic enzymes
- Direct entry of molecules into the cell nucleus
- Passive diffusion through the cell membrane
Why are receptors of multicellular organisms specific for given molecules/ligands?
Why are receptors of multicellular organisms specific for given molecules/ligands?
- To inhibit intracellular pathways
- To regulate specific cell functions (correct)
- To prevent signal transduction
- To allow non-specific signaling
