1. The correct answer is d. all. Enzymes are biological catalysts that speed up chemical reactions in living organisms. They are proteins, which are a type of macromolecule.<br /><br />2. The correct answer is b. speed up a chemical reaction. Enzymes facilitate and accelerate chemical reactions by lowering the activation energy required for the reaction to occur.<br /><br />3. The correct answer is b. substrate. The term for the substance that an enzyme acts upon is called a substrate. Enzymes bind to their specific substrates and catalyze the chemical reaction.<br /><br />4. The correct answer is A. Active site. The active site is the region on an enzyme where the substrate binds. It is a specific region on the enzyme that has a complementary shape and chemical environment to the substrate, allowing for the formation of the enzyme-substrate complex and the catalysis of the reaction.
