LO 9.1: Explain how the redox reactions of catabolic pathways yield energy by oxidizing organic fuels. 1. Explain the difference between fermentation and aerobic respiration. Fermentation is a partial degradation of sugars or other organic fuel that occurs without the use of oxygen.
Section Review 9-2. Pyruvic acid is the product of glycolysis and becomes one of the reactants in the Krebs cycle. It is broken down into carbon dioxide to produce ATP. Glycolysis is the first step in cellular respiration.
Chapter 9: Cellular Respiration and Fermentation. 1. Explain the difference between fermentation and cellular respiration.
Chapter 9: Cellular Respiration: Harvesting Chemical Energy Overview: Before getting involved with the details of cellular respiration and photosynthesis, take a second to look at the big picture. Photosynthesis and cellular respiration are key ecological concepts involved with energy flow.
##### 9 LESSON. 1 Energy and Life Chemical Energy and ATP. KEY QUESTION Why is ATP useful to cells? Cells require energy to perform work, and energy makes life possible. We humans cannot use sunlight as a source of energy, but must take in food made by other organisms, plant or animal, to acquire energy. We are heterotrophs. Heading Main Idea
Photosynthesis generates oxygen and organic molecules that the mitochondria of eukaryotes use as fuel for cellular respiration. Cells harvest the chemical energy stored in organic molecules and use it to regenerate ATP, the molecule that drives most cellular work.
