- Which of the following is a description of an example of the second law of thermodynamics? Some chemical energy in glucose transforms to chemical energy in ATP. O The kinetic energy of wind turns the blades of a wind turbine. The chemical energy in gasoline is transformed to kinetic energy to drive a car. The mechanical energy of flowing water turns a turbine. Some chemical energy in gasoline is transformed to heat while driving a car.arrow_forwardYou and a friend are eating dinner together, and a number of events occur during your dinner that call to mind the Laws of Thermodynamics. Match each event to the most relevant Law of Thermodynamics. Your food is cooked on a propane grill, which converts the chemical energy from propane and oxygen into the heat used to cook the food, First Law of Thermodynamics Second Law of Thermodynamics Your meals arrive, and your friend enjoys eating her steak, which contains chemical energy that will be converted into other forms of chemical energy within her body. After the meal, you go for a walk. The chemical energy from dinner will help generate ATP to fuel the skeletal muscles used for walking. The waiter brings a basket of bread, but as you eat it crumbs are scattered on the table. Your glass of water falls off the table and breaks into many pieces.arrow_forwardCan the thermodynamic property Δ G° be used to predict the speed of a reaction in a living organism?

Define the exergonic and endergonic processes.arrow_forwardWhich of the following statements is most directly described by the first law of thermodynamics? A B с D The synthesis of highly-ordered biomolecules is coupled with the production of heat energy. All energy-transferring processes involve the loss of some of that energy into an unus- able form. Enzymes reduce the activation energy of chemical energy by stabilizing substrates at their transition states. The energy for the synthesis of glucose is provided by the absorption of light energy in chlorophyll pigments.arrow_forward
