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...

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...

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 the difference between standard free energy change and actual free energy change? Correct Answer-Standard free energy is for a reaction occurring under standard conditions while actual free energy is for a reaction occurring under a different set of initial conditions that aren't standard If Q>KEQ Correct Answer-Free energy is positive If Q<KEQ Correct Answer-Free energy is negative If Q=KEQ Correct Answer-reaction is at equilibrium and free energy is zero What is the ...
