Look at the cross section of a cell membrane of a eukaryotic cell. H+ ions are being pumped from a low concentration to a high concentration.
active transport
passive transport
facilitated diffusion
co-transport
A person with swollen gums rinses his mouth with warm salt water, and the swelling decreases. Which of the following has occurred?
The swollen gums have absorbed the saltwater solution
The saltwater solution lowers the temperature of the water in the gums
The salt in the solution has moved against the concentration gradient.
The water in the gums has moved out due to the high concentration of salt in the solution.
The cell membrane of the red blood cell will allow water, oxygen, and carbon dioxide to pass through. Because other substances are blocked from entering, this membrane is called
perforated
semi-permeable
non-conductive
permeable
What is the advantage of cells being so small?
Small cells contain a greater quantity of enzymes than large cells.
Small cells do not require energy and get everything they need from osmosis
The cell has a smaller surface area to volume ratio which means it can move nutrients into the cell and waste out more efficiently.
The cell then has a larger surface area to volume ratio which means it can move nutrients into the cell and waste out more efficiently.
Carrot sticks that are left in a dish of freshwater for several hours become stiff and hard. Similar sticks left in a saltwater solution become limp and soft. From this we can deduce that the freshwater is ______ and the saltwater is ________ to the cells of the carrot sticks.
hypotonic, hypertonic
hypotonic, hypotonic
hypertonic, hypertonic
hypertonic, hypertonic
In an emergency trauma room, a doctor accidentally gives a patient a large transfusion of distilled water directly into one of his veins instead of blood. Predict what might happen if distilled water was given to the patient instead of blood.
have no unfavorable effect as long as the water was sterile
have serious, perhaps fatal effects because there would be too much fluid for the heart to pump
have serious, perhaps fatal effects because the red blood cells would tend to shrivel
have serious, perhaps fatal effects because the red blood cells would tend to burst
A beaker is divided into two halves, A & B, by a membrane that is freely permeable to the water and NaCl but not to protein. Side A is half-filled with a solution of 8% protein, while side B is half filled with a 2% protein solution. Predict what would happen to side A after a few hours.
The number of protein molecules has increased.
The number of water molecules has decreased
The number of water molecules has increased.
The percentage of water has decreased.
How are cellular respiration and photosynthesis related, in terms of energy?
The energy captured in photosynthesis is used to power cellular respiration
The energy transformed in cellular respiration is used to power photosynthesis
Photosynthesis and respiration perform the same task in terms of energy transformation.
Energy is not involved in either photosynthesis or cellular respiration.
In which way are photosynthesis and cellular respiration different?
Cellular respiration stores ATP, while photosynthesis releases ATP
Cellular respiration produces oxygen, while photosynthesis uses oxygen.
Photosynthesis releases energy, while cellular respiration stores energy
Photosynthesis used carbon dioxide, while cellular respiration produces carbon dioxide.
A diagram representing the relationship between photosynthesis and cellular respiration is shown below. The numbered boxes in the diagram represent which of the following?
1 - water; 2 - nitrogen
1 - nitrogen; 2 - oxygen
1 - oxygen; 2 - carbon dioxide
1 - carbon dioxide; 2 – water
A potted plant is placed inside a clear, sealed vacuum container that has water pumped into it on a regular basis. The container is placed in the sun and the plant’s growth is monitored. Which statement best describes what will most likely happen to the plant over time?
The plant will grow faster because it is sheltered from the wind.
The plant will die because it does not have oxygen for photosynthesis
The plant will die because it does not have carbon dioxide for photosynthesis
The plant will grow at a slower rate because it requires more water.
Mike has four aquatic plants of the same size and the same species. He submerges the plants in a separate beaker filled with 200 ml of water. He then sets each beaker under a different intensity of light. Mike observes that, of the four plants, the plant in the beaker under the most intense light gives off the most gas bubbles in a 20 minute period. Which of the following statements best explains Mike’s observations?
Cells decompose most quickly under the most intense light
Water evaporates from plants faster under the most intense light
Photosynthesis occurs at the highest rate under the most intense light.
Gases in the leaves of plants expand most under the most intense light
Which process takes place in the presence of oxygen and produces nearly 20 times as much as ATP as glycolysis alone?
photosynthesis
lactic acid fermentation
aerobic respiration
alcoholic fermentation
Which of the following structure is where photosynthesis occurs in the cell below?
nucleus
chloroplast
mitochondria
endoplasmic reticulum
Two different species of bacteria are examined. Scientists find that species X always produces CO2 and H2O during cellular respiration. Species Y always produces ethyl alcohol and CO2. Which conclusion can be made from these observations?
Only species Y is aerobic
Only species Y is anaerobic.
Both species X and Y are aerobic.
Both species X and Y are anaerobic.
