(a) Temperature: Increasing temperature generally increases enzyme activity up to a point, as it provides more energy for molecular collisions. However, beyond the enzyme’s optimal temperature, the enzyme can denature and lose its activity. (b) pH: Each enzyme has an optimal pH range, and changes in pH can alter the enzyme’s shape, affecting its ability … Read more
The activation energy is the energy required to initiate a chemical reaction. For a reaction to occur, reactant molecules must collide with enough energy to break bonds and form new ones. Enzymes lower the activation energy by providing an alternative pathway for the reaction with a lower energy barrier. This is achieved by binding to … Read more
An enzyme is a biological catalyst, usually a protein, that speeds up the rate of a specific biochemical reaction by lowering the activation energy. Enzymes are highly specific for their substrates, meaning they catalyze only one type of reaction or work on one specific substrate. Their characteristics include: Specificity: Each enzyme works on a specific … Read more
