To identify the missing substances in the electron transport chain sequences. Concept introduction: Electron transport chain is a sequence of biochemical reactions in which electrons and hydrogen atoms from the citric acid cycle are transferred to various intermediate carriers and finally reacts with molecular oxygen to form a water molecule. There are four complexes associated with the electron transport chain that is present in the inner mitochondrial membrane. The four complexes that help in the electron transfer in the electron transport chain are: Complex I: NADH-coenzyme Q reductase Complex II: Succinate-coenzyme Q reductase Complex III: Coenzyme Q-cytochrome c reductase Complex IV: Cytochrome c oxidase An overview of the electron transport chain is as follows:

To learn more about the role of the electron transport chain in generating energy during respiration in this organism, you use two drugs. These drugs can each pick up electrons from specific intermediates in the pathway as shown above. You treat cells carrying out respiration with either a saturating dose of drug A or B, so that all the electrons which would normally continue along the pathway are captured by the drug in question. Complete the following table. In the presence of drug A, will the rate of ATP synthesis increase, decrease, or stay the same? Explain your reasoning. In the presence of drug B, will the rate of ATP synthesis increase, decrease, or stay the same? Explain your reasoning.

Describeenergy consumed vs released in reactions. Differentiate between endergonic vs exergonic reactions, anabolism vs catabolism, and coupled reactions.

The difference between catabolism and anabolism is that one involves the breakdown of larger molecules into smaller molecules and the other involves the formation of larger molecules from smaller molecules. True or False True False
