Unformatted text preview: Initial Reactant Final Product ATP NADH 15. If oxygen is present, pyruvate will enter the mitochondria matrix where the enzyme of the Citric Acid cycle will compete the oxidation of glucose. Pyruvate dehydrogenase complex acts on pyruvate to catalyze three reactions. What are these reactions? 16. Fill in the blanks in the diagram of the citric acid cycle. Balls represent carbon atoms. 17. For each turn of the citric acid cycle, how many of the following molecules are used or produced: Molecule used/produced per Molecules used/produced per turn of the cycle glucose molecule Acetyl CoA CO2 NADH FADH2 ATP 18. What specific process connects the flow of electrons down the electron transport chain and the synthesis of ATP. Where are electron transport chains located in the cell? Below is a list of molecules found in the electron transport chain. Number the molecules from the least (1) to the most electronegative (5)? Cyt a ( ) Cyt b ( ) Cyt a3 ( ) Q ( ) FMN ( ) 19. What molecule is the terminal electron acceptor within the mitochondrial matrix? Label the diagram of oxidative phosphorylation. 20. The exergonic flow of electron down the electron transport chain is used to pump H+ across the inner mitochondrial membrane and into the intermembrane space. Based on this information would you expect the pH of the intermembrane space to be higher or lower than the pH of the mitochondrial matrix? What is...
