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...

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...

Biology 114 Exam 2 Questions and Answers 100% Pass How does photosynthesis influence global warming caused by greenhouse gases? Photosynthesis can help alleviate global warming by removing carbon dioxide from the air. What occurs during oxidation and what happens during reduction in terms of electron transfer? Oxidation involves losing electrons, while reduction involves gaining electrons. At which stage of meiosis do synapsis and crossing over happen? Prophase I Where within t...
