Collins Collins Assignment 1 Begin your first experiment by developing a hypothesis to predict what will happen to oxygen consumption in the reaction flask after the addition of pyruvate. Develop a second hypothesis to predict how oxygen consumption will change in the flask upon the addition of pyruvate and ADP.

Copyright ? 2011 Pearson Education, Inc. - 1 - Name_______________________Period___________ Chapter 10: Photosynthesis This chapter is as challenging as the one you just finished on cellular respiration. However, conceptually it will be a little easier because the concepts learned in Chapter 9?namely, chemiosmosis and an electron transport system?will play a central role in photosynthesis. 1. As a review, define the terms autotroph and heterotroph. Keep in mind that plants have mitochondria and chloroplasts and do both cellular respiration and photosynthesis! Autotroph: An organism that obtains organic food molecules without eating other organisms or substances derived from other organisms. Autotrophs use energy from the sun or from oxidation of

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.

Chapter 9: Cellular Respiration, Harvesting Chemical Energy The principles of energy harvest Cellular respiration and fermentation are catabolic energy yielding pathways Cells recycle ATP they use for work Redox reactions release energy when electrons move closer to electronegative atoms Electrons ?fall? from organic molecules to oxygen during cellular respiration The ?fall? is stepwise during respiration via NAD+ and an electron transport chain The process of cellular respiration Respiration involves glycolysis, Krebs cycle and electron transport Glycolysis harvests chemical energy by oxidizing glucose to pyruvate The Krebs cycle completes the energy yielding oxidation of organic molecules

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
