Document Summary

Biol 112 biology of the cell review session for mid-term 1. Temperature raise will lead to faster simple and facilitated diffusion. Temperature change will also affect active transport, because enzymes are altered by temperature: explain the difference between channel and carrier proteins. Channel proteins do not change shape to let molecules pass through the membrane: explain the directionality of macromolecules in a cell. Nucleic acid: 3" hydroxyl group to 5" phosphate group. Amino acid: amide group to carbonyl group: predict the location of amino acids in a cell. Hydrophilic nature: exterior of membrane: explain the difference between primary and secondary active transport. The higher the temperature, the more fluid the membrane: explain permanent dipole and induced dipole. Permanent dipole = elements with high electronegativity (on) bond with elements with low electronegativity (schp); example: water. Induced dipole = elements with same affinity of electrons bond; example: ch3.
