activation energy correct answers energy needed to get a reaction started Delta G (change in G - change in free energy) correct answers respresented in a reaction coordinate diagram. Positive is thermodynamically unfavorable. Negative is thermodynamically favorable (exergonic - release energy). = G(products) - G(reactants) enzyme correct answers catalyze chemical reaction. Lower activation energy. Biological catalyst (protein) enzyme inhibition correct answers results in decrease in act...

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 Means that a...

energy Answer - the ability to do work, is everywhere in all systems, all of this comes from the sun or from food, ALWAYS conserved law of conservation of energy Answer - says that energy can be converted from one form to another, energy cannot be destroyed potential energy Answer - stored energy, includes the chemical energy available in biological molecules, batteries and gas kinetic energy Answer - energy of movement, includes light, heat or electricity kinetic energy, potential e...

What is the relationship between photosynthesis and cell respiration? Be sure to include the overall chemical equation for both reactions correct answer: The relationship between cell respiration and photosynthesis is an inverse relationship, that both sides are opposite each other. In photosynthesis, CO2 is taken in, and O2 is excreted, while in cellular respiration, C02 in excreted, and O2 is needed for the reaction to commence. Distinguish between oxidation and reduction. Why are these p...

You are studying two reactions. The only difference in these reactions is that one has an enzyme and the other does not. Which of following statements must be false? A. The enzymatic reaction has less activation energy because it does not have a transition state. B. The activation energy of the reaction that lacks an enzyme is greater than the reaction that has an enzyme. C. The rate of reaction is greater in the enzymatic reaction. D. The delta G and the entropy of both of the reactions a...

Bio 198 Exam 5 KSU Questions and Answers Already Passed What is the first law of thermodynamics? And how does it pertain to cells? Energy cannot be created or destroyed Cells can't just create their own energy, they need a source. What is the second law of thermodynamics? And how does this pertain to cells? Energy is transferred, and in every transfer some energy is lost. Cells need a constant input of energy because they lose some as heat What is an endergonic reaction? A react...
