- 1. Multiple ChoiceWhich process takes place in the presence of oxygen and produces nearly 20 times as much as ATP as glycolysis alone?photosynthesislactic acid fermentationcellular respirationalcoholic fermentation
- 2. Multiple ChoiceIf a plant died from lack of food, which structure is most likely missing or damaged?flowerrootstemleaves
- 3. Multiple Choice
Which of the following structure is where photosynthesis occurs in the cell?nucleuschloroplastmitochondriaendoplasmic reticulum - 4. Multiple ChoiceA weightlifter is using heavy weights in short bursts for a competition. Because his muscle cells are not able to take in enough oxygen to make very much ATP the weightlifter begins to get fatigue in his muscles. Which of the following processes is most likely going on in the muscles of the weightlifter as he competes in his event?As the cells run out of oxygen they switch to fermentation, which allows the cell to make small amounts of ATP in the absence of oxygen.As the cells run out of oxygen, they die off gradually and the weightlifter's muscles have fewer contracting muscle cells.The cells will never run out of oxygen if the weightlifter is breathing.As the cells run out of oxygen, they will continue to make the same amount of ATP, since oxygen is not required to make ATP.
- 5. Multiple ChoiceWhich of the following structure is where cellular respiration occurs in the cell?nucleuscytoplasmmitochondriavacuoles
- 6. Multiple ChoiceWhich process do the animals in the food web use to convert energy from food into ATP?cellular respirationosmosisphotosynthesistranscription
- 7. Multiple ChoiceA diagram representing the relationship between photosynthesis and cellular respiration is shown.
The numbered boxes in the diagram represent which of the following?1 - water; 2 - nitrogen1 - nitrogen; 2 - oxygen1 - oxygen; 2 - carbon dioxide1 - carbon dioxide; 2 – water - 8. Multiple ChoiceWhich of the following equations best represents photosynthesis?C + O2 + H2O = CO2 +HOH6CO2 + 6H2O = C6H12O6 + 6O26C + 6 H2O = C6H12O6C6H12O6 = 6CO2 + 6H2O
- 9. Multiple ChoiceWhy are there less air bubbles as the plant is place further away from the light sourcebecause cellular respiration decreases when there is less lightbecause the light independent reaction decreases when there is less lightbecause photosynthesis decreases as a plant is moved further away from a light sourcethe wavelength increases as a plant is placed further away from a light source
- 10. Multiple ChoiceOne of the principal compounds that living things use to store energy isDNAATPH20CO2
- 11. Multiple ChoiceTwo 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 and uses cellular respiration.Only species Y is anaerobic and uses fermentation.Both species X and Y are aerobic.Both species X and Y are anaerobic
- 12. Multiple ChoiceWhat are the reactants in the equation for cellular respiration?oxygen and lactic acidcarbon dioxide and waterglucose and oxygenwater and glucose
- 13. Multiple ChoiceWhat happens during photosynthesis?Heterotrophs consume ATP.Heterotrophs produce ATP.Autotrophs consume carbohydrates.Autotrophs produce carbohydrates.
- 14. Multiple ChoiceWhat is the correct equation for cellular respiration?6O2 + C6H12O6 -> 6CO2 + 6H2O + Energy6O2 + C6H12O6 + Energy -> 6CO2 + 6H2O6CO2 + 6H2O -> 6O2 + C6H12O6 + Energy6CO2 + 6H2O + Energy -> 6O2 + C6H12O6
