Signal transduction
Signal transduction is the process by which cells communicate and respond to signals from their environment. When a signaling molecule, like a hormone or neurotransmitter, binds to a receptor on a cell's surface, it triggers a series of biochemical events inside the cell. This process often involves proteins and other molecules, leading to a specific response, such as changes in gene expression, metabolism, or cell behavior. Essentially, it's how cells "talk" to each other and make decisions based on external information, helping coordinate functions in organisms.

Signal transduction is the process by which cells respond to external signals, like hormones or environmental changes. It begins when a signaling molecule binds to a receptor on a cell's surface, triggering a series of reactions inside the cell. These reactions often involve proteins that relay the signal, amplifying it as it moves through various pathways. Ultimately, signal transduction leads to a specific response, such as changes in gene expression, metabolism, or cell behavior. This process is essential for cells to communicate and adapt to their surroundings, playing a crucial role in overall bodily functions.

Signal transduction is the process by which cells respond to signals from their environment. When a signal, such as a hormone or neurotransmitter, binds to a receptor on a cell's surface, it activates a cascade of reactions inside the cell. This can lead to changes in gene expression, enzyme activity, or other cellular functions. Essentially, it’s how cells communicate and process information, allowing them to adapt to changes, regulate functions, and coordinate activities with other cells. This process is crucial for maintaining health and responding to various stimuli.
