KSU Bio 198 Exam 5 Practice Questions and Correct Answers

Is respiration an endergonic (requires energy input) or exergonic (releases energy) reaction? exergonic Which of the following is NOT a stage of aerobic cellular respiration? Calvin Cycle glycolysis oxidative phosphorylation Krebs Cycle calvin cycle What is the net gain of ATP through the process of glycolysis? 2 ATP What is the metabolic process that can produce ethanol or lactic acid as a product? fermentation __________________ is a type of exergonic (release energy or "energy exiting") chemical reaction, and __________________ is a type of endergonic (require energy / energy input) chemical reaction. oxidation (lose electron), reduction (gain electron) Which of the following processes requires external energy (such as ATP) to transport molecules? Osmosis Active transport Facilitated Diffusion Diffusion Active transport The phospholipid bilayer of the cell membrane (aka the plasma membrane) is selectively permeable. Which of the following types of molecules CAN pass directly through the plasma membrane? small, non-polar (no charge) molecules Endocytosis and exocytosis are ________________ transport processes that involve movement of molecules via _______________ through the cell membrane. active (require energy), vesicles or vacuoles In the overall photosynthesis reaction, ________________ and ___________________ are the reactants, and __________________ and ____________________ are the products. carbon dioxide and water; oxygen and glucose Which of these is NOT true in regards to the characteristics of photosystems? photosystem II gets its electrons from the splitting of water photosystem II gets its electrons from the splitting of glucose a photosystem consists of a light-harvesting complex (containing pigment molecules) and a reaction center where electrons are energized electrons gotten from from the end of photosystem II's electron transport chain are passed to photosystem I photosystem II gets its electrons from the splitting of glucose Which membrane-bound protein phosphorylates (adds a phosphate to) adenosine diphosphate (ADP) to create adenosine triphosphate (ATP)? ATP synthase Which of the following is NOT a characteristic of electron transport chains? it drives a process called chemiosmosis it creates an electrochemical gradient of H+ ions (protons) that drives energy generation it must be driven by electrons gotten from the splitting of glucose it must be driven by electrons gotten from the splitting of glucose
