KIN 270 Chapter Notes - Chapter 2: Maltose, Blood Plasma, Alpha Helix
Document Summary
Matter: made up of atoms: solid: constant volume and shape, liquid: constant volume but changes shape, gas: changes volume and shape. Electron cloud: contains electrons, determines reactivity of atom. Valence shell: outermost shell that determines bonding. Elements: determined by the atomic number or number of protons of an atom. Isotopes: are the specific version of an element based on mass number (protons and. 1: covalent bonds: strong electron bonds involving shared pairs of electrons, non polar: equal sharing of electrons, polar: unequal sharing, forms polar molecules i. Example: h20: hydrogen bonds: weak polar bonds based on partial electrical attractions between adjacent molecules, surface tension: caused by hydrogen bonds between water molecules. Work: a change in mass or distance. Kinetic energy: energy of motion, increases as potential decreases. Potential energy: stored energy, decreases as kinetic increases. Chemical energy: potential energy stored in chemical bonds. Chemical reactions: decomposition reaction (catabolism): breaks chemical bonds.
