5943450252Endergonic-Absorbs energy from surrounding environment -Not spontaneous0
5943455761Exergonic-Energy is released -Spontaneous1
5943474688Anabolic-Energy is put in to make simple substances combined into complex structures2
5943480480Catabolic-Energy is released when the breakdown of complex material turns into simple substances3
5943487109Spontaneous Chemical Reaction-Potential energy of the reactants is greater than that of the products4
59435068414 Major Biological MacromoleculesCarbohydrates, Lipids, Proteins, Nucleic Acids5
5943525037Carbohydrates-Provides energy for the body -3 subtypes: monosaccharide, disaccharide, polysaccharide6
5943538930Lipids-Hydrophobic, nonpolar, store energy, provide insulation, make up cell membranes, building block for hormones -Examples: fats, oils, waxes, phospholipids, steroids7

5943894288Amino Acids-Contain: R group, amino group, alpha carbon, and carboxylic acid group -Attached by peptide bonds17
5943937134Starch-Stored form of sugars in plants -Made of two polysaccharides (amylose and amylopectin)18
5943949806Triglycerides-Primarily stored in specialized fat cells (adipocytes)19
5943956188SaturatedThe fatty acid has only single bonds between neighboring carbons in a hydrocarbon chain20
