response to sucrose

Definition

Target type: biologicalprocess

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a sucrose stimulus. [GOC:jl]

Response to sucrose is a complex biological process involving a series of steps that enable organisms to sense and utilize sucrose as a nutrient source. Sucrose, a disaccharide composed of glucose and fructose, is a major energy source for many organisms. The process begins with the perception of sucrose by specific receptors on the cell surface. These receptors, often transmembrane proteins, bind to sucrose molecules triggering a signaling cascade within the cell. This cascade involves a series of intracellular events, including changes in protein phosphorylation and activation of specific enzymes. The signal transduction pathway ultimately leads to the activation of genes involved in sucrose metabolism. These genes encode enzymes such as invertases, which break down sucrose into glucose and fructose, allowing the organism to utilize these sugars for energy production and growth. The response to sucrose can also involve changes in gene expression that affect other physiological processes, such as cell growth, development, and stress response. The specific mechanisms involved in sucrose perception and signaling vary depending on the organism. However, the overall process is conserved across many organisms and is essential for their ability to utilize sucrose as a nutrient source.'
