After photosystem I energizes electrons, these electrons are used to reduce NADP+ to NADPH. What is the role of the NADPH, along with ATP from photosystem II, in the Calvin cycle?

Challenging Collin is the senior manager at Midore Partners, a private equity firm, that owns 100% of the stock of QuickWay, a mid-sized regional retailer. Given the rise of Amazon and the big two national retailers (Target and Wal-Mart), Collin is considering proposing shutting down QuickWay’s operations. The firms 24 locations are expected to generate a cash flow from assets of $[CFA1x],000,000 net year, but that the firm’s market share (and, therefore, CFA) would shrink by [gx] percent per year indefinitely. Collin is confident that he can sell off QuickWay’s real estate and current inventory for $[CFA0x],000,000. Retail investments are required to return [rx] percent per year. What is the NPV of shutting down QuickWay’s operations? Enter your answer in dollars, rounded to the nearest $1  

The central metabolic pathways of aerobic respiration are split between the cytoplasm and the mitochondria in eukaryotic cells. Glycolysis takes place in the cytoplasm, while the citric acid cycle and the electron transport chain occur in the mitochondria. How does the endosymbiotic theory explain this spatial separation?

The process of cellular respiration “charges” ADP by adding a third phosphate group to create ATP. The energy for this process is stored in the newly formed chemical bond. What type of energy is being stored within the bonds of the ATP molecule?

The rise of an oxygen-rich atmosphere had profound impacts on life. Which of the following is a major benefit of an oxygen atmosphere for complex life forms?

Adenosine triphosphate (ATP) is the primary energy currency of the cell. Its structure consists of a nitrogenous base called adenine, a five-carbon sugar called ribose, and three phosphate groups. Based on these components, ATP is classified as which type of macromolecule?

A scientist is studying biochemical pathways in a bacterium, those that break down complex molecules to release energy, and those that use that energy to build new, complex molecules. What two major categories of metabolic processes are they studying?

The human stomach produces gastric acid with a pH between about 1.5 to 3.5. If an individual with a gastric acid pH of 2.0 drinks coffee with a pH of 5.0, how does the pH of each of these (the gastric acid and coffee) compare?

A yeast cell is performing aerobic respiration. What are the final waste products and main energy output of this process?

Consider what you have learned in Unit 2 of this class. Please pick a single topic, e.g., a single learning objective we have covered. This might be something you found especially interesting, something you initially struggled with but then learned well, something you are especially confident of and perhaps wished was covered more thoroughly on this test, or anything else you want from this content, except please do not pick one of the topics already discussed in the essay questions (i.e., do not re-discuss the essay questions you already answered). For this topic: Identify the topic Explain the topic and why it is important Write a single multiple choice question addressing this topic Your answer should be a paragraph of at least 4-5 sentences. Please do not just list out names of multiple topics, or just tell me that you found a topic to be really interesting. You may tell me you found this topic especially interesting, but you must demonstrate that you learned about and understand this topic by explaining it clearly. Note that there is not a single answer to this question, this is your chance to demonstrate good knowledge of any topic of your choosing from your work in this unit!
