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?

9.4: During oxidative phosphorylation, chemiosmosis couples electron transport to ATP synthesis. The electron transport chain and the electron flow down the chain is coupled to ATP synthesis. The electron transport chain is a collection of molecules embedded in the inner membrane of the mitochondrion in eukaryotic cells. Most components of the chain are proteins. Tightly bound to these proteins are prosthetic groups, nonprotein components essential for the catalytic functions of certain enzymes. During the e- transport along the chain, e- carriers alternate between reduced and oxidized states as they accept and donate e-. Each component of the chain becomes reduced when it accepts e- from its ?uphill? neighbor, which has

9.1: Catabolic pathways yield energy by oxidizing organic fuels. Redox reactions: oxidation and reduction. The stages of cellular respiration. In redox reactions the loss of e- from one substance is called oxidation. The gain to the other is known as reduction. The harvesting of energy from glucose by cellular respiration is a cumulative function of three metabolic stages: Catabolic pathways and production of ATP Organic compounds possess potential energy because of the arrangement of electrons in bonds between atoms. Compounds that participate in exergonic reactions can act as fuel. Enzymes help cells degrade complex organic molecules that are rich in potential energy. This breakdown can provide energy to
