Question 22

Enzymes are biological catalysts, and most enzymes are proteins. Some RNA molecules (ribozymes) can act as enzymes, but the most common and typical answer here is Proteins. The other options: Lipids are for energy storage/structure, Carbohydrates for energy, Nucleic acids (like DNA/RNA) have other roles (though ribozymes are nucleic acid enzymes, the primary answer for "what are enzymes made of" in basic biology is Proteins).

Enzymes are biological catalysts. Their main function is to speed up (catalyze) chemical reactions in cells by lowering the activation energy required for the reaction to occur. They do not get used up in the process and can be reused.

Step 1: First Step (Enzyme + Substrates)

The first part of the diagram shows the enzyme and the substrates. Substrates are the reactant molecules that the enzyme acts on. The enzyme has an active site that is complementary in shape to the substrate(s). So, substrates approach the enzyme's active site.

Step 2: Second Step (Enzyme - Substrate Complex)

In the next step, the substrates bind to the enzyme's active site, forming an enzyme - substrate complex. This is a temporary complex where the enzyme and substrate interact closely.

Step 3: Third Step (Reaction Occurs)

While in the enzyme - substrate complex, the chemical reaction occurs. The enzyme helps to break (or form, depending on the reaction) bonds in the substrate(s).

Step 4: Fourth Step (Enzyme + Product)

After the reaction, the products are formed and then released from the enzyme's active site. The enzyme is then free to bind to new substrate molecules and catalyze more reactions.
