BIOL 1500: FINAL EXAM REVIEW ACTUAL 2025/2026 QUESTIONS AND 100% CORRECT ANSWERS Yeast cells grown anaerobically can obtain energy by fermentation, which results in the production of? - Answer -ATP, CO2, and ethanol Which of the following statements about NAD+ is true? - Answer -NAD+ is reduced to NADH during glycolysis Carbon dioxide (CO2) is released during which of the following stages of cellular respiration? - Answer -oxidation of pyruvate to acetyl CoA and the citric acid cycle A glucose molecule is completely broken down to carbon dioxide and water in glycolysis and the citric acid cycle, but together these two processes yield only a few molecules of ATP. What happened to most of the energy that the cell obtains from the oxidation of glucose? - Answer -It is stored in NADH and FADH2 Which of the following describes the process of glycolysis? - Answer -It represents the first stage in the chemical oxidation of glucose by a cell Which of the following metabolic pathways requires a proton gradient? - Answer -oxidative phosphorylation In the process of cellular respiration, what is consumed, and what is produced? - Answer -Glucose is consumed, and carbon dioxide is produced Which of the following metabolic pathways occur(s) in the cytosol of eukaryotic cells? - Answer -glycolysis and fermentation In the complete oxidation of a molecule of glucose (C6H12O6) in aerobic cellular respiration, how many molecules of ATP are produced by substrate-level phosphorylation? - Answer -4 Need assistance on Online classes, Exams & Assignments?

Answer -Two molecules of ATP are used, and four molecules of ATP are produced Two molecules with the chemical formulas C6H12O6 and C6H12O2 are probably - Answer -a monosaccharide and a fatty acid Where in mitochondria is the enzyme ATP synthase localized? - Answer -inner membrane Which of the following is true of the energy levels of electrons in shells? - Answer -Valence electrons have a higher energy level than those in other filled shells Which of the following terms describes metabolic pathways that break down complex molecules to release stored energy? - Answer -catabolic pathways Where are the proteins of the electron transport chain located in a eukaryotic cell? - Answer -inner mitochondrial membrane What is the source of the energy used to generate the proton gradient across the inner mitochondrial membrane? - Answer -redox reactions in the electron transport chain Identify all correct statements about the basic function of fermentation. - Answer -The basic function of fermentation is the regeneration of NAD+, which allows continued ATP production by glycolysis Which of the following sequences represents the correct order in which metabolic reactions occur during the complete oxidation of glucose through aerobic respiration? - Answer -glucose → glycolysis → pyruvate oxidation → citric acid cycle → electron transport chain A covalent bond is likely to be polar when - Answer -one of the atoms sharing electrons is more electronegative than the other Upon completion of glycolysis, what is the fate of the majority of the Need assistance on Online classes, Exams & Assignments?
