 Describe 3 types of chemical bonds/interactions in proteins. | 1. Covalent/peptide = peptide linkage in a chain of amino acids as the primary structure 2. Disulfide covalent = bridge between two sulfur R groups in tertiary or quarternary structure 3. Hydrogen = H-O or H-N R groups in secondary, tertiary, or quarternary structure as an alpha helix or beta pleated sheet. |
| Discuss how the structure of a protein affects enzyme activity and cell signaling. | Enzyme Activity = changes shape due to changes in pH and temperature levels. Cell Signaling = gap junctions; shape of junctions allows for passage of regulatory ions or molecules. & Immune signaling: leads to activation of cells. |
| Explain the genetic basis of abnormal hemoglobin | Point mutation in DNA; base substitution leading to a different amino acid in the hemoglobin. |
| Explain why sickle cell anemia would be optimal in some areas of the world. | Changed hemoglobin leads to oxygen-deprivation minimizing malarial infection. Heterozygotes maintain a reproductive advantage/success. |
