Detailed explanation-1: -Essentially, an enzyme is a specific type of protein that performs a very specific function. Enzymes function to regulate biochemical reactions in living things, in this sense, they operate solely as a functional protein, while a protein can be either functional or structural.
Detailed explanation-2: -The proteins in enzymes are usually globular. The intra-and intermolecular bonds that hold proteins in their secondary and tertiary structures are disrupted by changes in temperature and pH. This affects shapes and so the catalytic activity of an enzyme is pH and temperature sensitive.
Detailed explanation-3: -Catalysts are substances that increase or decrease the rate of a chemical reaction but remain unchanged. Enzymes are proteins that increase rate of chemical reactions converting substrate into product.
Detailed explanation-4: -Enzymes bind substrates at key locations in their structure called active sites. They are typically highly specific and only bind certain substrates for certain reactions.
