    1. Which of the following statements is true? (1 point) Since all cells carry out cellular respiration, they contain mitochondria. A cell cannot be subdivided into smaller units that maintain the living state. Plant cells contain chloroplasts and no mitochondria while animal cells contain mitochondria and no chloroplasts. The cell membrane’s function is to prevent diffusion of any substances into or out of the cell. 2. A biologist discovers a new unicellular organism and classifies it as a prokaryote. The cell is very small, contains a cell membrane, a cytoplasm, DNA in a nucleus, and no other cell organelles. Which statement below represents a correct response to the biologist’s discovery and classification? (1 point) The organism is a prokaryote, because it lacks cell organelles such as mitochondria, Golgi apparatus, and endoplasmic reticulum. The organism is a prokaryote, because it is so small and simple in structure. The organism is a eukaryote, because it has a nucleus. The organism is a eukaryote, because it has a cell membrane, a cytoplasm, and DNA. 3. Which structures are used by the cell for storing and maintaining biological information that will be passed to daughter cells when the cell divides? (1 point) nucleus, chromatin nucleolus, ribosome vacuole, lysosome Golgi apparatus, endoplasmic reticulum 4. What problem do organisms that live in fresh water have? (1 point) The fluid in their cells is hypotonic with respect to the external environment and so they have to be able to pump water out. The fluid in their cells is hypotonic with respect to the external environment and so they have to be able to pump water in. The fluid in their cells is hypertonic with respect to the external environment and so they have to be able to pump water out. The fluid in their cells is hypertonic with respect to the external environment and so they have to be able to pump water in. 5. What is the role of water in the reactions of photosynthesis? (1 point) provides oxygen atoms provides electrons accepts electrons acts as a catalyst 6. The following aquariums were set up with the same volume of water. (Elodea is an aquatic green plant.) aquarium 1: Elodea only aquarium 2: Elodea and an aquatic snail aquarium 3: Aquatic snail only Which aquariums will establish a cycle of carbon dioxide and oxygen gas flow if placed in the dark for several weeks? (1 point) 1, 2, and 3 2 and 3 3 only none 7. Which of the following are energy carrier molecules involved in photosynthesis? (1 point) ATP only ATP and NADPH ATP, NADH, and FADH2 NADPH, NADH, and FADH2 8. Which of the following shows the correct order of events during cellular respiration? (1 point) pyruvate oxidation, glycolysis, electron transport, Krebs cycle glycolysis, Krebs cycle, pyruvate oxidation, electron transport glycolysis, pyruvate oxidation, Krebs cycle, electron transport pyruvate oxidation, Krebs cycle, glycolysis, electron transport 9. How do the quantities of ATP formed during aerobic and anaerobic respiration compare? (1 point) Two times more ATP is formed during aerobic respiration than during anaerobic respiration. Four times more ATP is formed during aerobic respiration than during anaerobic respiration. Eight times more ATP is formed during aerobic respiration than during anaerobic respiration. Eighteen times more ATP is formed during aerobic respiration than during anaerobic respiration. 10. Wine is made by mixing yeast with grapes and allowing the yeast cells to undergo fermentation. Sparkling wine is a type of wine that contains high levels of dissolved carbon dioxide. What is the source of the carbon atoms in the carbon dioxide found in sparkling wine? (1 point) ethanol lactic acid methane glucose

    |dw:1353079887066:dw|let me to take the rest then: 8: glycolysis, pyruvate oxidation, Krebs cycle, electron transport 9:Eighteen times more ATP is formed during aerobic respiration than during anaerobic respiration (depending how you calculate the amount of ATP (a bit diffrent from place to place) 10: glucose (ethanol is formed from pyruvate by a decarboxylation and is done bu the enzyme decarboxlyase and after that alcohol dehydrogenase do the last reaction. See drawing)
