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.

Cellular Respiration?An Overview 1 Cellular Respiration?An Overview What are the phases of cellular respiration? Why? All cells need energy all the time, and their primary source of energy is ATP. The methods cells use to make ATP vary depending on the availability of oxygen and their biological make-up. In many cases the cells are in an oxygen-rich environment. For example, as you sit and read this sentence, you are breathing in oxygen, which is then carried throughout your body by red blood cells. But, some cells grow in envi- ronments without oxygen (yeast in wine-making or the bacteria that cause botulism in canned food), and occasionally animal cells must function without sufficient oxygen (as in running sprints). In this

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

Breanna Takacs AP Biology A2 11/27/12 Cellular Respiration Free Response Questions The Krebs Cycle and oxidative phosphorylation are both processes involved in obtaining ATP from pyruvate, the end product of glycolysis. Before the Krebs Cycle actually begins, pyruvate combines with coenzyme A to produce acetyl CoA. One NADH and one CO2 are produced. Then the Krebs Cycle begins when citrate is formed by combining acetyl CoA with OAA. 3NADH, 1 FADH2 are made and CO2 is released. It is possible for the Krebs Cycle to be a cycle because the last product is OAA which reacts with acetyl CoA.

Acetyl CoA ? the product of the transition reaction between glycolysis and the Krebs cycle, pyruvate is oxidized to Acetyl-CoA by NAD+ , also producing CO2, and NADH Aerobic ? Requiring free oxygen: any biological process that can occur in the presence of gaseous oxygen. Alcohol Fermentation ? The process by which yeast turns sugar into carbon dioxideCO2) and alcohol. Anaerobic ? Any process that can occur without oxygen, such as anaerobic fermentation or H2S photosynthesis. ATP Synthase ? An enzyme that catalyzes the formation of ATP from the phosphorylation of ADP with inorganic phosphate, using a form of energy, such as the energy from a proton gradient.
