ATP • ATP stands for adenosine triphosphate • ATP is the molecule that supplies

ATP • ATP stands for adenosine triphosphate • ATP is the molecule that supplies energy that can be used quickly and easily by cells • ATP could be used for many things: – – Contracting muscles Transmitting signals Move flagella Moving materials in the cell Biggs et al.

ATP Structure • ATP (adenosine triphosphate) is made up of three parts: – A

ATP Structure • ATP (adenosine triphosphate) is made up of three parts: – A nitrogen base (adenine) – A sugar (ribose) – Three phosphate groups that are held together with high energy bonds Think. Quest

ATP ADP • ATP releases energy by losing a phosphate group and becoming ADP

ATP ADP • ATP releases energy by losing a phosphate group and becoming ADP • adenosine triphosphate becomes adenosine diphosphate • When it transfers a phosphate, it transfers energy • This energy drives the cell’s metabolism. • ADP can later bind with another Georgia State University

ATP ADP • To supply cells with energy, the high energy ATP bond is

ATP ADP • To supply cells with energy, the high energy ATP bond is broken. ADP is formed and energy is released. ATP ADP + Phosphate + Energy • Energy is used (and stored) by reattaching a phosphate group to ADP forming ATP to be used later. ADP + Phosphate + Energy ATP • Less energy is used to make ATP than is released when it is broken
