Unformatted text preview: 1 Lecture 4 Basic Chemistry ● Chemistry: ​ smallest atoms and its subatomic parts (protons, neutrons, electrons) ○ protons: have a positive charge, inside nucleus ○ electrons: have a negative charge, allow atoms to bind outside, allows for stability ○ neutrons: have a neutral charge ● Isotopes: ​ have different number of neutrons Types of Bonds ● ● ● ● ● ● Covalent: ​ electrons shared in pairs among different atoms Single covalent: ​ share one pair of electrons (2 electrons) Double covalent: ​ share 2 pairs of electrons (4 electrons) Polar: ​ultiple sharing, not equal m Non­polar: ​ electrons equally circulating/shared Ionic: ​ contains a charge, capable of conducting current in a fluid ○ electrolytes are an example of ionic bonds ○ NaCl → Na+ + Cl ­ 2 Types of Reactions ● Synthesis: ​ take small pieces and synthesize together to create one large component ○ also known as ​ anabolism ​r ​ ​ anabolic reactions o ○ Na + Cl → NaCl + heat (Energy from another reaction) ● Decomposition: ​ take large pieces, decompose them into smaller components ○ also known as ​ catabolism or catabolic reactions ○ **​ Catabolism + Anabolism = metabolism*​ * ○ ATP → ADP + P₁ + heat + Energy Types of Energy ● Kinetic energy: ​ energy movement, energy “now” ● Potential energy: ​ stored energy ...
