ATP-ADP Cycle

ATP-ADP Cycle Transformation of Energy Energy is the ability to do work. Thermodynamics is the study of the flow and transformation of energy in the universe.

ATP-ADP Cycle Laws of Thermodynamics First law - Energy can be converted from one form to another, but it cannot be created nor destroyed. Second law - Energy cannot be converted without the loss of usable energy.

ATP-ADP Cycle ATP – ADP Cycle ATP (Adenosine Triphosphate) transfers energy from the breakdown of food molecules to cell functions Energy is released when a phosphate group (Pi) is removed ADP (Adenosine Diphosphate) is changed into ATP when a phosphate group (Pi) is added

ATP-ADP Cycle ATP – ADP Cycle phosphate removed

ATP-ADP Cycle Carbohydrates Carbohydrates are the molecules most commonly broken down to make ATP. not stored in large amounts up to 36 ATP from one glucose molecule

ATP-ADP Cycle Lipids Lipids store the most energy. 80 percent of the energy in your body About 146 ATP from a triglyceride

ATP-ADP Cycle Proteins Proteins are least likely to be broken down to make ATP. amino acids not usually needed for energy about the same amount of energy as a carbohydrate
