ATP/ADP
2
Name things that run on batteries?
Do now 11/13 Name things that run on batteries? Then tell me what molecule inside of your body acts like batteries.
3
ENERGY ATP - Adenosine Triphosphate
Stores chemical energy released from cellular respiration releases energy for life processes by losing one phosphate to create ADP (Adenosine diphosphate) Stores energy released from food by adding a phosphate to ADP
4
Which molecule has more stored energy?
Battery Comparison Which molecule has more stored energy? ATP
5
Chemical Energy & Food Calorie: energy needed to raise the temperature of 1 gram of water by 1 degree Celsius Chemical energy stored in food (glucose) is released by breaking chemical bonds during cellular respiration
6
RELEASES stored energy
ATP / ADP Cycle ATP STORES energy REMOVE a phosphate ADD a phosphate RELEASES stored energy ADP
7
ATP / ADP Chemical Reactions
Reactants Products (start with) (end with) ATP ADP + P ADP + P ATP Hydrolysis enzymes + Water + Energy Dehydration synthesis enzymes + ? + Energy + ? + Water
8
Law of conservation of energy
Energy can neither be created nor destroyed. It can only be transformed into different forms.
9
What are the different kinds of energy?
How does energy present itself? Is all energy the same? List a couple of ways in which energy presents itself.
