The specific substances (metabolite) that fits on the enzyme surface and is converted to products is called
Correct answer: D. Substrate
- A. Co-factor
- B. Prosthetic group
- C. Isoenzyme
- D. Substrate
Explanation
Substrate binds to the active site on the enzyme surface and is converted into products.Co-factors are non-protein molecules or ions that are required for the proper functioning of certain enzymes. They can assist enzymes in carrying out their catalytic functionsProsthetic groups are non-protein components that are tightly bound to enzymes and are essential for their catalytic activity. They can be considered as specialized co-factors that are permanently attached to the enzyme, assisting in the enzyme's function.Isoenzymes are different forms of an enzyme that catalyze the same reaction but differ in their amino acid sequence, subunit composition, or other properties.In enzyme-catalyzed reactions, the substrate is the specific molecule or metabolite that binds to the active site of the enzyme. The active site is a region on the enzyme's surface that is complementary in shape and chemical properties to the substrate. When the substrate binds to the active site, it undergoes a series of chemical reactions facilitated by the enzyme, leading to the conversion of the substrate into a product.

About Enzymes
Enzymes are biological catalysts that lower activation energy without being consumed, and their specificity is explained by the lock and key and induced fit models. Work includes the effects of temperature, pH and substrate concentration on reaction rate, plus competitive and non-competitive inhibition and how these differ.
