SPARCO 01374 22. Lipids would produce with the carbohydrate of same weight. Compared (a) more (b) less e) the same an 23. Where are the proteins of electron-transport chain located in mitochondria for the cellular respiration? (a) matrix (b) outer membrane inner membrane (d) both membranes 24. The flow of protons during the light reaction of photosynthesis is from thylakoid space to stroma and back to thylakoid space through the ATPase? True (b) False 25. Which of the following process takes place only in the stroma of chloroplast? Calvin cycle (b) Krebs cycle (c) Glycolysis (d) chemiosmosis 26. The citric acid cycle can produce FAD (a) NADPH (b) FADH2 ) both a and b 27. The alcohol fermentation produces (a) ethanol only (b) lactate only and CO2 (d) lactate and CO2 (c)ethanol 28. Which of the following polymers of glucose is used as a vehicle to store energy reserves in animal cells? a glycogen (c) starch (d) glycerol ) glucagon 29. In the final step of the citric acid cycle, oxaloacetate is regenerated through the oxidation of malate and this is coupled with the production of which other molecule? GTP (d) CO2 (a) NADH (b) FADH2 30. The link between bond-forming reactions and membrane transport processes in the mitochondria is called (a) electron transfer )ATP synthesis (b proton pumping (d) chemiosmotic coupling 31. In the light reaction of photosynthesis, light energy is harnessed to produce (a) ATP only (b) NADPH only (c) Glucose only (d) both a and b 32. The light reaction of photosynthesis helps to build up protons in the of chloroplast? a stroma (c) intermembrane spaceExplanation / Answer
Q.22 lipids would produce MORE energy than carbohydrates of the same weight.
Because lipids have more single covalent bonds than carbohydrates. So when lipids are used as energy source they release more energy.
Q.23 Proteins of electron transport chains are located in the inner membrane of mitochondria for cellular respiration.
Mitochondria is power house of cell where enegy is generated. inner membrane of mitochondria is placewhere protein of ETC are located and they transport H ions in inner membrane space where proton gradients is created and using thet gradient energy (ATP) are produced. In the mitochondrial matrix kreb cycle is operated.
Q.25 Calvin cycle occurs only in STROMA of chloroplast.
Because all enzymes of calvin cycle are located in Stroma. Glycolysis occurs in cytosol, kreb cycles occurs in mitochondrial matrix.chemiosmosis occurs on inner membrane of mitochondria.
Q.26 citric acid cycle produces both FADH2and NADPH.
NADPH and FADH2 produced during citric acid cycle are utilized in electron transport chain to generate ATP.
1 acetyl CoA molecule when undergoes 1 round of citric acid cycle it produces 3 NADPH, 1FADH2 and 1 ATP/GTP.
