Energy 1. Energy is used to cycle materials between high and low energy states 2. Producers and consumers o Producers make energy-rich molecules Stored energy, building blocks for all living matter Energy can later be extracted - released by a breakdown of energy-rich food molecules in mitochondrial respiration This breakdown forms ATP 3. ATP o Formed with the energy from breaking down energy-rich food molecules o Consists of 3 phosphate groups, a sugar, and a nitrogenous base o NADH: Carrier for H o Energy from ATP to do work: A living cell must perform several kinds of energy-consuming work to stay alive Mechanical work - High energy P is transferred to mechanical proteins Transport work - High energy P is transferred to transport proteins Chemical work - High energy P is transferred to reactive molecules Enzymes 4. Properties o Types of proteins o Catalysts - improve the speed of chemical reactions o
