Temperature significantly influences enzyme activity by affecting the rate of biochemical reactions. Enzymes are proteins that catalyze reactions, and their activity typically increases with temperature due to enhanced molecular movement. However, there is an optimal temperature range; beyond this, enzymes may denature, losing their functional shape and activity. This relationship is crucial in biological processes, as temperature variations can impact metabolism, growth, and overall organism health. Understanding this influence is vital for fields like biochemistry and physiology.
