Metabolism: correct answer: Catabolism + anabolism Catabolism: correct answer: Breakdown/ degradation of macromolecules = net gain of energy. -cells use energy conversion strategy that oxidizes glucose. -Small bits of energy are released at several points in the pathway called ATP (energy currency) Anabolism: correct answer: Buildup of macromolecule = loss of net energy Stages of Catabolism: correct answer: Stage 1: hydrolysis of macromolecules into smaller micro molecules/ subuni...

Title: Organic Synthesis Purpose: In this lab, three carbon based organic compounds were synthesized to determine their true purity. The experiments were done to learn about how to use these compounds’ melting points and infrared spectroscopy to determine their percent yield. Procedure: Experiment 1: Making Acetylsalicylic Acid (aspirin) 1. Obtain a flask. 2. Weigh 2 grams of salicylic acid. 3. Put the 2 grams of salicylic acid into the flask. 4. Put 5 mL of acetic anhydride into a gr...
