Definition
Biochemical signaling refers to the process by which cells communicate with each other through the release and detection of chemical signals, such as hormones or neurotransmitters. This signaling regulates various physiological processes, including growth, metabolism, and immune responses.
Summary
Biochemical signalling is a fundamental process that enables cells to communicate and coordinate their activities. It involves the release of chemical signals that bind to specific receptors on target cells, triggering a cascade of events that lead to a cellular response. This process is essential for maintaining homeostasis, regulating growth, and responding to environmental changes. Understanding biochemical signalling is crucial for various fields, including medicine and biotechnology. It has significant implications in drug development, where targeting specific signalling pathways can lead to effective treatments for diseases such as cancer and diabetes. By studying the mechanisms of signalling, researchers can develop strategies to manipulate these pathways for therapeutic purposes.
