Question

Enzymes are mainly composed of:

• A. carbohydrates
• B. nucleic acids
• C. globular proteins
• D. fibrous proteins

Answer 1

Answer: (C)

globular proteins

Enzymes are mainly composed of globular proteins. When an enzyme is formed, it is made by stringing together between 100 and 1,000 amino acids in a very specific and unique order. The chain of amino acids then folds into a unique shape. That shape allows the enzyme to carry out specific chemical reactions -- an enzyme acts as a very efficient catalyst for a specific chemical reaction. Enzymes are, in general, globular proteins.
