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...
