7. Which of the following is an example of passive transport? a) Sodium-potassium pump b) Endocytosis c) Osmosis d) Exocytosis 8. Alcoholic fermentation is an important process in baking and brewing. Yeast cells are used to ferment sugars producing carbon dioxide and ethanol. If a baker accidentally kills the yeast cells high temperatures before baking the dough, what would be the most likely outcome for the bread? a) The bread will taste sour because ethanol will still be produced. b)The bread will not rise because carbon dioxide will not be produced. c) The bread will rise but will have no flavor because no ethanol will be produced. d) The bread will rise more slowly because aerobic respiration will occur instead. 9. A biologist is studying an algae species that uses photosynthesis. She places the algae in a sealed container with a constant light source and measures the levels of oxygen and carbon dioxide in the container over time . If the light is turned off for 24 hours, what will most likely happen to the levels of oxygen and carbon dioxide in the container? a) Oxygen levels will rise, and carbon dioxide levels will fall. b) Oxygen and carbon dioxide levels will remain constant. c) Oxygen levels will rise, and carbon dioxide levels will also rise. d) Oxygen levels will fall , and carbon dioxide levels will rise as cellular respiration continues in the absence of photosynthesis. 0. What is the primary energy carrier in cells? A)ATP b) NADH c) FADH2 d) ADP 1. Which of the following is a product of photosynthesis? a) Qucose b) ATP c) Carbon dioxide d) Water

7. The correct answer is c) Osmosis. Osmosis is a type of passive transport that involves the movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration. It does not require energy input from the cell.<br /><br />8. The correct answer is b) The bread will not rise because carbon dioxide will not be produced. Yeast cells are responsible for fermenting sugars and producing carbon dioxide during the process of alcoholic fermentation. If the yeast cells are killed by high temperatures, they will not be able to produce carbon dioxide, which is necessary for the bread to rise.<br /><br />9. The correct answer is d) Oxygen levels will fall, and carbon dioxide levels will rise as cellular respiration continues in the absence of photosynthesis. When the light is turned off, the algae will no longer be able to perform photosynthesis, which produces oxygen as a byproduct. As a result, the oxygen levels in the container will decrease, and the carbon dioxide levels will increase as the algae continue to respire and use up the available oxygen.<br /><br />10. The correct answer is a) ATP. ATP (adenosine triphosphate) is the primary energy carrier in cells. It is produced during cellular respiration and is used as a source of energy for various cellular processes.<br /><br />11. The correct answer is a) Glucose. Glucose is a product of photosynthesis. During photosynthesis, plants use sunlight, carbon dioxide, and water to produce glucose and oxygen. Glucose is an important source of energy for plants and is also used by other organisms as a source of energy.
