Overview
Signal transduction pathways are essential for cellular communication, allowing cells to respond to external signals and adapt to their environment. These pathways involve a series of steps, starting from the binding of a ligand to a receptor, leading to the activation of second messengers and kinas...
Key Terms
Example: Hormones like insulin act as ligands.
Example: Insulin receptors on cell surfaces.
Example: cAMP is a common second messenger.
Example: Protein kinase A (PKA).
Example: Phosphorylation of enzymes can change their activity.
Example: One activated receptor can lead to the activation of many second messengers.
