BIO 103 EXAM #2 ACTUAL 2025/2026 QUESTIONS AND 100% CORRECT ANSWERS What are sugars? - Answer --Building blocks of carbohydrates. - Make mechanical supports. -Major Energy source. What are some examples of structural sugars? - Answer --Chitin in Fungi and insect exoskeletons. -Cellulose in plant cell walls. What do Monomers make? - Answer --Polymers. Oligosaccharide is what? - Answer -A small sugar 3-9 monosaccharides. What are two storage molecules? - Answer -Glycogen and Starch. Why do animals store sugar as glycogen? - Answer -To solve osmotic problem. What is Glycolysis? - Answer -Glycolysis is the metabolic pathway in which Glucose (sugar) is broken in to pyruvate. This pathway is to produce ATP (energy). In general how do we make energy? - Answer -We make energy by oxidizing organic molecules or stealing energy. How are Electrons transfered around the cell?

What is AcetylCoA? - Answer -Acetyl Coenzyme A is a High energy chemical group that is highly exergonic when it's thioester bond is broken. Why is glycolysis primitive? - Answer -1. All do it the same way. 2. not associated with organelles. 3. No O2 required. 4. Mitochondria require the end product. 5. Intermediates are used as starting points for metabolic pathways. What happens to Pyruvate? - Answer -In anaerobic conditions: Ethanol fermentation: 1 pyruvate AcetylAldehyde - ethanol. and lactic acid fermentation: Pyruvate - Lactate. In Aerobic Conditions: Enters mitochondrial membrane becomes acetylcoa and goes through cellular respiration (lots of ATP). Where does Glycolysis and Aerobic respiration occur in Bacteria? - Answer -In the Cytosol. Draw and Label Glycolysis. - Answer -... Draw and label a Mitochondria. - Answer -... 1 pyruvate yields how much ATP? - Answer -15-17 ATP. What determines the number of Mitochondria in a Cell? - Answer -The Energy requirements of that cell (sperm flagellum). Draw pathway in to a mitochondria.
