Acids and bases are usually demoted as strong or weak, what's the difference? - Answer-- Strong acids and bases - reaction with water is approximately 100% - Weak acids and bases - reaction with water is much less than 100% What does acid and base strength not dictate? - Answer-Acid or base strength is not a measure of concentration What are some examples of strong acids? - Answer-HNO3, HCl, H2SO4 and HClO4 are strong acids What are electrolytes and what's the connection to acids? - Ans...

Metabolism (catabolism and anabolism) - Metabolism: sum of total chemical reactions in an organism, also the method by which cells extract and use energy from their environment. Catabolism: The process by which stored nutrients and ingested foods are converted to a usable form of energy. It produces simple products CO2, H2O, NH3, and building blocks such as sugars and fats that are used in anabolism. Anabolism: the process by which simple products and building blocks of catabolism are us...
