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...

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...

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...
