Pre-Lab Questions 1. The first law of thermodynamics discusses the interplay between heat and work and how they come together to describe the internal energy changes of a system undergoing a thermodynamic process. Importantly, though, the first law of thermodynamics is, at its core, a statement about the conservation of energy. Energy cannot be created or destroyed. it cannot vanish into nothingness or spontaneously appear. This law can be stated mathematically as: ΔU=Q−W Explain howth...

Membranes (both outside and inside the cell) correct answer: Not a static structure, very important for cell function. They contain proteins that are very complex and vital to cell life. Mitochondria membranes correct answer: Very vital for the cell, has both an inner and outer membrane. What drives membrane formation? correct answer: A decrease in ionic interactions with water / limiting the hydrophobic interactions drives membrane formation. Lipid tails are ... correct answer: Hyd...
