Exergonic - Study guides, Class notes & Summaries

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...

What is a metabolic pathway? - correct answer A pathway that a molecule goes through, resulting in a specific product. What is metabolism? - correct answer The totality of an organisms chemical reactions Gibbs free energy - correct answer Portion of a system that can perform work when temp and pressure are uniform throughout the system. What does a negative Delta G mean? - correct answer A process that is spontaneous/exergonic What does spontaneous mean? - correct answer Me...

Anabolic pathways usually involve ____. Answers: a. Reduction of Metabolites b. Release of PPi c. Production of ATP d Release of CO2a Diffusion of compounds - e.g. ions, atoms, or molecules - down a gradient is ___ because it ___. Answers: a. Endergonic; does not involve bond formation. b. Exergonic; produces heat. c. Exergonic; increases entropy. d. Exergonic; separates like chargesc

Describe the First and Second Laws of Thermodynamics and explain why they are important to the cellular energetics. 1st - energy cannot be created or destroyed, only change forms. • This is important because all living things need a constant energy source (the sun) 2nd - when transforming energy, some is lost as heat (10% between trophic levels) Define endergonic and exergonic reactions and describe how they are linked in cellular energetics. Endergonic - requires energy (hydrolysis; splittin...
