organisms including all plants and animals require energy for their cellular processes. In biological processes‚ the immediate energy source is often in the form adenosine triphosphate (ATP). The nucleotide ATP maintains both catabolic and anabolic reactions. An example of a catabolic reaction is respiration where large molecules are broken down into smaller ones with energy released. An example of an anabolic reaction is photosynthesis where small molecules are built up into larger ones using energy

CHAPTER 7 LECTURE SLIDES Respiration • Organisms can be classified based on how they obtain energy: • Autotrophs – Able to produce their own organic molecules through photosynthesis • Heterotrophs – Live on organic compounds produced by other organisms • All organisms use cellular respiration to extract energy from organic molecules Cellular respiration • Digestion – enzymes breaking down large macromolecules into smaller ones. • Cellular respiration is a series of reactions

Chapter 9 Study Guide 1. Explain the difference between aerobic respiration and fermentation. Fermentation is partial degradation of sugars that occurs without oxygen. Aerobic respiration consumes organic molecules and oxygen and yields ATP. 2. Diagram for photosynthesis and respiration 3. What are redox reactions? What is the difference between reduction and oxidation reactions? Redox reactions are chemical reactions that transfer between reactants. In oxidation‚ a substance loses

without it‚ cells and body tissue could not get important nutrients for survival. In humans and animals‚ diffusion is needed during respiration. It is the way oxygen travels from the lungs to the red blood cells in the blood and the way carbon dioxide travels from the blood to the lungs from where it can be exhaled. In the oxidative phosphorylation stage of aerobic respiration‚ diffusion is vital in getting the protons across the potential gradient from the inter-membranal space to the inner membrane to

called Photosynthesis. The food that they produce is the sugar glucose. Animals and other organisms are heterotrophs (other- feeders). They must consume other organisms (plants) in order to eventually get their glucose. Both plants and animals use glucose as an input to the process of Cellular Respiration (another subject) to produce ATP molecules. ATP molecules are the energy source for all metabolic processes.
