Chemical signalling: Insulin – Online course
Signalling molecules such as hormones and neurotransmitters allow cells to sense and respond to changes in the external environment. Signalling molecules interact with receptors and trigger a range of molecular interactions inside cells, which are specific for the molecule and cell type.
The hormone insulin acts on many cells in the body and is vital for regulating glucose homeostasis. Diabetes occurs when insulin is not produced or when there are defects in insulin action. Explore how insulin acts on muscle cells with this narrated animation.
