What do you understand by: (i) Activation energy. (ii) Enzyme active site. (iii) Enzyme specificity. Describe the different mechanisms that explain enzyme action. Discuss the three factors that affect the rate of enzyme action.

Here are the answers to the questions from the image: 1) a) What do you understand by: i. Activation energy: Activation energy is the minimum amount of energy required for a chemical reaction to occur. It is the energy barrier that must be overcome for reactants to transform into products. ii. Enzyme active site: The enzyme active site is the specific region on an enzyme molecule where substrate molecules bind and undergo a chemical reaction. It has a unique three-dimensional shape complementary to its specific substrate. iii. Enzyme specificity: Enzyme specificity refers to the ability of an enzyme to catalyze only one type of reaction or act on only one specific substrate or a very limited range of substrates ✂️ _That answer was long and got cut off.
