Which of the following statements related to enzymes is correct? 1. They are proteins. 2. They perform their functions in the same location where they are produced in the body. Choose the correct answer using the codes given below:

• Enzymes are biological proteins that catalyze biochemical reactions. They are globular proteins and play a significant role in increasing the rate of biochemical reactions without being consumed in the process. • Statement 1 is correct, as enzymes are indeed proteins. • Statement 2 is incorrect because enzymes are typically produced in one location of the body (like the liver or pancreas) but may perform their functions at different sites (for example, enzymes secreted by the stomach perform their function in the stomach). • Therefore, the correct answer is (a) Only 1.
