ATP-ADP Cycle

Heterotrophs Autotrophs But first….. Can NOT make own food… they get their energy by the foods they eat Make their own food with light – phototrophs with chemicals -- chemotrophs

ATP Adenosine triphosphate P JOB--- store & release energy + ribose - adenine P ribose + -

ADP Adenosine diphosphate P JOB--- energy can be stored by adding another Phosphate.. and becoming ATP Adenosine diphosphate + - adenine P ribose

ATP ADP P P + + Releasing energy Storing energy - - Releasing energy adenine P ribose Releasing energy adenine P ribose Storing energy

ATP-ADP Cycle ATP – ADP Cycle phosphate removed

HEAT Transformation of Energy Energy is the ability to do work. Thermodynamics is the study of the flow and transformation of energy in the universe. 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. HEAT

Carbohydrates Lipids Proteins most commonly broken down to make ATP. not stored in large amounts up to 36 ATP from one glucose molecule Lipids store the most energy. 80% of energy in your body About 146 ATP from a triglyceride Proteins least likely to be broken down to make ATP. amino acids not usually needed for energy about the same amount of energy as a carb.

ATP-ADP Cycle

Using Biochemical Energy 1) Movement in cell 2) Protein synthesis 3) Active Transport (Low to high concentration across membrane)
