Unformatted text preview: • How does it store energy? o Lies in its triphosphate group o Phosphate groups are highly negatively charged, and thus they strongly repel one another o Therefore, the covalent bonds between them are highly unstable o Since they are unstable, they have a low activation energy, and are easily broken in hydrolysis (negative G). ← ← all chemical reactions carried out by an organism is called metabolism • those chemical reactions that expend energy to make or transform chemical bonds are called anabolic reactions or anabolism • reactions that harvest energy when chemical bonds are broken are called catabolic reaction, or catabolism 07/04/2008 23:55:00 ← 07/04/2008 23:55:00 ←...
