Unformatted text preview: 2. Release energy – Exergonic reaction Chemical Equilibrium ATP – energy currency 1. Can be used in a lot of different chemical reactions 2. Most common 3. Has Adenine as base 4. ATP is an nucleotide 5. Most energetic b/c It has 3 phosphate groups 6. Building block of nucleic acdis 7. Hydrolysis of ATP- Releases a lot of amount of energy, has to do with the separation b/c P and O 8. Can be use to phsophorylate many molecules 9. ATP ydrolysis: ATP + H2O ADP + Pi + free energy a. Exergonic reaction b. ΔG = -7.3 kcal/mol in lab c. ΔG can be up go -14kcal/mol under cellular conditions ΔG is positibe – krequiresa energy for the reaction to occur Catalyst Substance that speeds up chemical reactions w/o being permanently altered in the process No catalys can make a reaction occur that cannot otherwise occur Most catalysis are proteins called enzymes...
