Vocabulary Entropy- a thermodynamic quantity representing the unavailability of a system's thermal energy for conversion into mechanical work, often interpreted as the degree of disorder or randomness in the system Catabolism- the breakdown of complex molecules in living organisms to form simpler ones, together with the release of energy; destructive metabolism. Anabolism- the synthesis of complex molecules in living organisms from simpler ones together with the storage of energy; constructive metabolism. Cellular Respiration- the metabolic processes whereby certain organisms obtain energy from organic molecules Glycolysis- the breakdown of glucose by enzymes, releasing energy and pyruvic acid.

Glycolysis Worksheet ? Answer Sheet 1. Explain why the phosphate end of ATP stores potential energy. Each of the phosphate groups is negatively charged. These negative repel each other and so they would have less energy if they were further apart. 2. Which has more potential energy, ATP or ADP? ATP has more potential energy than ADP since it has three negatively charged phosphates held together vs only two in ADP. 3. Write the overall reaction for cellular respiration. Glucose + 6 O2 6 CO2 + 6 H2O (+ energy in the form of ATP and heat) 4. What atom is known as an ?electron grabber? because it attracts electrons so strongly? oxygen 5. What is an electron transport chain?
