What are the three components typically involved in the cell signaling process?
What are the three components typically involved in the cell signaling process?
- The signal, the nucleus, and the cytoplasm
- The signal, the receptor, and the effector (correct)
- The receptor, the enzyme, and the substrate
- The ligand, the channel protein, and the neurotransmitter
Why are peptide ligands unable to diffuse freely across the bi-lipid layer of the plasma membrane?
Why are peptide ligands unable to diffuse freely across the bi-lipid layer of the plasma membrane?
- Because they are polar and hydrophilic molecules (correct)
- Because they are positively charged
- Because they are nonpolar and hydrophobic molecules
- Because they are small in size

Study Notes
Cell Signaling Components
- Three components typically involved in the cell signaling process: receptor, signal transduction pathway, and response
Peptide Ligands
- Peptide ligands unable to diffuse freely across the bi-lipid layer of the plasma membrane because of their hydrophilic and large size
Chemical Signals Composition
- Chemical signals mostly composed of amino acid derivatives, including peptides and proteins, and steroids
Hormone Classification
- Most hormones belong to the class of steroid or peptide hormones
Cell Signaling Classification
- Cell signaling can be further classified into three types based on the distance over which it occurs: endocrine signaling (long distance), paracrine signaling (short distance), and autocrine signaling (same cell)
