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...

Henderson-Hasselbach Equation - pH = pKa + log ([A-] / [HA]) FMOC Chemical Synthesis - Used in synthesis of a growing amino acid chain to a polystyrene bead. FMOC is used as a protecting group on the N-terminus. Salting Out (Purification) - Changes soluble protein to solid precipitate. Protein precipitates when the charges on the protein match the charges in the solution. Size-Exclusion Chromatography - Separates sample based on size with smaller molecules eluting later. Ion-Exchange...

adenosine triphosphate (ATP) - energy currency of life, high energy molecule that stores energy we need to do anything. Universal unit of energy exhange NAD+, nicotinamide adenine dinucleotide - coenzyme in all living cells. Required for fundamental biological processes. Oxidized form active transport - requres energy. molecules move against concentration gradient. Ex. protein channels, endocytosis, exocytosis. Can be coupled to exergonic chemical reactions or exergonic movement of molecul...

Enzymes – Biochemistry Questions and Answers with Verified Solutions What is the primary function of enzymes in biological systems? Enzymes act as catalysts, speeding up chemical reactions without being consumed in the process. How do temperature and pH affect enzyme activity? Enzymes have optimal temperature and pH ranges where they function best; deviations can lead to reduced activity or denaturation. What is the active site of an enzyme? The active site is the specific re...

Lecture 9 What is the energy of activation delta G knot double dagger? Correct Answer-it is the Energy difference between going from the ground state at the beginning to this high energy state which represents by the transition state what is the delta delta G knot double dagger? Correct Answer-which a reflection of how effective an enzyme which lowers the overall energy of activation. True Correct Answer-T/F Enzymes do not change the Final equilibrium state. But it does help to get int...

MCAT: BiochemistryAmino Acids - correct answer - Found in proteins - amino group, carboxylic acid, hydrogen atom, and R group attached to a central alpha carbon - chiral (L) except glycine - (S) configuration except cysteine - join via peptide bonds Nonpolar, nonaromatic AA - correct answer glycine alanine valine leucine isoleucine methionine proline Aromatic AA - correct answer tryptophan phenylalanine tyrosine Polar AA - correct answer serine threonine asparagine glutam...
