Learn about intracellular signal transduction pathways and their role in cell communication and the cell cycle.
Types of neurotransmitter receptors (video) | Khan Academy
Learn how they can be excitatory or inhibitory, and how neurotransmitters can bind to multiple types of receptors. Discover the role of ionotropic and metabotropic receptors, and how they influence neuron behavior, from rapid effects to long-lasting changes.
The membrane potential - Khan Academy
If a membrane is less permeable to a molecule, it’s harder for that molecule to diffuse across the membrane. In this article, we'll see how a neuron establishes and maintains a stable voltage across its membrane – that is, a resting membrane potential.
G Protein Coupled Receptors - Khan Academy
G-protein coupled receptors (GPCRs) are a large, diverse group of membrane receptors in eukaryotes that respond to a wide range of external signals. When a ligand binds to a GPCR, it triggers a complex chain of events involving G-proteins and second messengers, influencing various cell functions.
