Document Summary

Reading guide for lesson 10 (pages 162 177, 180 181) Figure 9. 3 shows methane combustion as an example of a redox reaction. Explain in your own words how electrons are being transferred, what components are being reduced or oxidized, and why energy is released. In cellular respiration, glucose is oxidized and oxygen (o2) is reduced. Describe how hydrogen atoms moved from one compound to another in cellular respiration. In the end of cellular respiration, hydrogen atoms (and their electrons) end up bound to oxygen to form water. Explain why nad+ is considered to be oxidized and nadh is considered to be reduced. Describe how nadh transfers energy to oxygen using an electron transport chain. Figure 9. 5 to see how electrons fall down the electron transport chain, releasing energy along the way. Answer concept check 9. 1 question 2 on page 167 in the space below. Give a brief description of each of the main steps of cellular respiration.
