Question

1. amino acids: - the monomer building blocks of proteins are called _ - there are _ different amino acids. - draw the basic structure that all amino acids share: - what makes amino acids different? - amino acids form: _ (2 amino acids) _ (long chain of amino acids) - in a condensation reaction, 2 amino acids form a covalent bond called a _ _. this bond produces _ 3. enzymes: - what are enzymes? - enzyme reactions depend on a physical fit between the enzyme molecule and its _. - draw a lock and key model of enzyme action (fig. 3 - 13)

Explanation:

• The monomer building - blocks of proteins are amino acids. There are 20 different amino acids. Their basic structure has an amino group (-NH2), a carboxyl group (-COOH), a hydrogen atom, and a variable R - group attached to a central carbon atom. The R - group makes amino acids different. Two amino acids form a dipeptide, a long - chain of amino acids forms a polypeptide. In a condensation reaction, two amino acids form a peptide bond, producing water. Enzymes are biological catalysts (usually proteins) that speed up chemical reactions. Enzyme reactions depend on a physical fit between the enzyme molecule and its substrate.

Answer:

• The monomer building blocks of proteins are called amino acids.
• There are 20 different amino acids.
• Basic structure of amino acids: A central carbon atom bonded to an amino group (-NH2), a carboxyl group (-COOH), a hydrogen atom, and a variable R - group.
• What makes amino acids different: The R - group.
• Amino acids form: Dipeptide (2 amino acids), Polypeptide (long chain of amino acids).
• In a condensation reaction, 2 amino acids form a covalent bond called a peptide bond. This bond produces water.
• What are enzymes: Biological catalysts (usually proteins) that speed up chemical reactions.
• Enzyme reactions depend on a physical fit between the enzyme molecule and its substrate.
