- DURING THE TRANSITION REACTION: What is the substrate? What are the products? Why is this called “Transition”?Shown below are reduction potentials for four half-reactions. Which of the coupled reactions is favorable? (Note that for Cytochrome c you must multiply the reduction potential by 2 for each coupled reaction because only one electron is involved) a) 2 Cytochrome c (Fe3+) + H2O ó 2 Cytochrome c (Fe2+) + O2 b) NADH + Succinate- ó NAD+ + Fumarate- c) Fumarate- + H2O ó Succinate- + O2 d) All of the aboveHow is ATP and hydrogen atoms used in the dark reaction? That is, what are these products for (or what exactly is the dark reaction “trying to accomplish” and how are the two products of the light reaction used for this purpose)?
- What is the molecular logic that makes a pathway with a number of comparatively small energy changes more likely than a single reaction with a large energy change?How is ATP and hydrogen molecules used in the dark reaction? That is, what are these products for (or what exactly is the dark reaction “trying to accomplish” and how are the two products of the light reaction used for this purpose)?How many ATP are generated in link reaction ?
- What is the activation energy for a reaction? Why is activation energy necessary?Why do we refer to the conversion of six molecules of carbon dioxide (six carbon atoms) to one molecule of glucose (also six carbon atoms) as a net reaction?Based on this information, what type of enzyme would ornithine decarboxylase be? I searched it up on Google and sources say it is a lyase because it catalyzes cleavage without H2O, but in equation 1, isn't water part of the reaction? Is decarboxylase still a lyase because water is a reactant, not a catalyst?
