The text you provided seems to be a series of statements rather than a question. However, I can provide some clarification on these statements:

1. "Enzymes are proteins that catalyse chemical reactions." - This is correct. Enzymes are biological catalysts that speed up chemical reactions in the body. They are indeed proteins.

2. "Hydrogen bonding is not involved in protein secondary structure." - This is incorrect. Hydrogen bonding is crucial in the formation of a protein's secondary structure. Specifically, hydrogen bonds form between the backbone atoms of the amino acid chain, leading to structures like alpha-helices and beta-sheets.

3. "Proteins are polymers of amino acid monomers." - This is correct. Proteins are made up of chains of amino acids, which are the monomers. These chains fold into complex structures to form the protein.

4. "Proteins have complex three-dimensional shapes that effect reactivity." - This is partially correct. Proteins do have complex three-dimensional shapes, but these shapes affect, not effect, their reactivity. The shape of a protein determines its function and how it interacts with other molecules.

5. "The amino acid sequence is the primary structure of a protein." - This is correct. The sequence of amino acids in a protein is referred to as its primary structure. This sequence determines how the protein folds into its final three-dimensional shape.
