Quiz zum Vortrag
Which is a typical ligand for transmembrane receptors?
- Polar amino acids
- Hydrophobic molecules
- Free fatty acids
- Cholesterol
- Steroid molecules
Which is an INCORRECT statement regarding cell-to-cell communication?
- Hydrophilic molecules diffuse faster through cell membranes; thus, they are more efficient signaling molecules than hydrophobic molecules.
- Communication signals between two cells are transmitted via hydrophobic or hydrophilic signaling molecules.
- Owing to their hydrophobic nature, cholesterol-based steroid hormones (sex hormones) diffuse across cell membranes and bind to intracellular receptors to elicit a cellular response.
- Activated signal-specific receptors activate the signal transduction pathway in cells to elicit a cellular response.
- Signal-specific receptors are activated after interactions with signaling molecules.
