Glycolysis b. Transition reaction c. Electron transport chain d. Kreb cycle d. none of the above 4. Which of the following is the final product of photosynthesis? a. Co b. Sucrose c. Glucose 11. The small openings on the lower epidermis of leaves for gas exchange are usually called: a. cuticle d. ATP b. leaf hair c. stoma d. During the process of spermatogenesis, one permatogonium (mother cell) can give rise to how any sperms? stomata a. 12. After cellular respiration, the energy in onde molecule of glucose can give rise up to: a. 36ATP b. 38ATP c. c. 34ATP d. 2ATP In mitosis, splitting of centromeres occurs in ich stage? a. Prophase b. Anaphase c. Metaphase. d. Telophase 13. In eukaryotic cells, the Electron Transport Chain occurs in: a. mitochondria b. cell membrane c. chloroplastExplanation / Answer
1. exocytosis: Vesicles or other bodies in the cytoplasm move macromolecules or large particles across the plasma membrane. There are two types of vesicle transport, endocytosis and exocytosis, which require energy.
2. The order is 4,2,1,3. The steps of aerobic cellular respiration are: Glycolysis (the break down of glucose) Link reaction. Krebs cycle. Electron transport chain, or ETC.
3. None of teh above.
4. Glucose is the end product of photosynthesis reaction.
5. Divides by meiosis to produce two sperm cells.
6. Anaphase is the shortest phase of mitosis. In this stage, the centromeres split apart.
7. incomplete breakdown of glucose in absence of O2 to form pyruvate acid, lactic acid or alcohol and a few ATP, also known as fermentation
8. Cyanobacteria are oxygenic photosyntheticbacteria. They harvest the sun's energy, absorb carbon dioxide, and emit oxygen.
9. Sodium Chloride (0.9%) solutions are isotonic as indicated by their osmolarity.
10. Krebs cycle and the electron transport chain, which generate the largest amounts of ATP during cellular respiration, take place in the mitochondria.
11. The exchange of oxygen and carbon dioxide in the leaf (as well as the loss of water vapor in transpiration) occurs through pores called stomata
12. 38 ATP molecules can be made per oxidised glucose molecule during cellular respiration (2 from glycolysis, 2 from the Krebs cycle, and about 34 from the electron transport system).
13. The electron transport chain and ATP synthase are located on the mitochondrial inner membrane.
