- 1. Multiple ChoiceCells obtain energy by either capturing light energy through photosynthesis or by breaking down carbohydrates through cellular respiration. In both photosynthesis and cellular respiration, the energy is ultimately derived from the sun in ahighly efficient process which involves no loss of heat to the environment.one-way process.reversible process.pathway that involves taking in heat from the environment at each step.
- 2. Multiple ChoiceHow do cells get energy to perform their necessary functions?Cells get energy by dissolving waste products of the body.Cells get energy by moving water from one organelle to another.Cells get energy by taking in nutrients from food.Cells get energy only by taking in oxygen from the atmosphere.
- 3. Multiple ChoiceWhat is the function of stomata in plants?to transport materials from the soil to the leavesto allow gas exchange between the environment and the inside of leavesto absorb light energy from the Sunto transport materials from the leaves to the soil
- 4. Multiple ChoiceWhich of the following are reactants in the process of cellular respiration?glucose and oxygencarbon dioxide and waterglucose and watercarbon dioxide and oxygen
- 5. Multiple ChoicePhotosynthesis is carried out by which of the following?plants, but not animalsbacteria, but neither animals nor plantsanimals, but not plantsall living organisms
- 6. Multiple ChoiceAdenosine triphosphate, or ATP, is primarily used as __________ in living organisms.a blood coagulanta reproductive enzymea source of energya muscle relaxing hormone
- 7. Multiple ChoiceThrough the process of hydrolysis, cells remove phosphate groups from molecules of ATP to form molecules of ADP.
This hydrolytic reaction results inthe breaking of high-energy bonds to produce free energy.the formation of low-energy bonds to store free energy.the breaking of low-energy bonds to produce free energy.the formation of high-energy bonds to store free energy. - 8. Multiple ChoiceDuring cellular respiration, the bonds of food molecules are broken, so energy can be released to fuel other cellular processes. In order for this to occur, which of the following statements must be true?The energy in the new compounds that are formed must be equal to the energy in the bonds of the food molecules.New compounds with lower-energy bonds must be formed when the high-energy bonds in food molecules are broken.The new compounds that are formed must be more complex than the food molecules that were broken down.New compounds with higher-energy bonds must be formed when the low-energy bonds in food molecules are broken.
- 9. Multiple Choice
A plant cell is shown.
Cellular respiration occurs in the __________ .cell wallchloroplastmitochondrionvacuole - 10. Multiple ChoiceDuring the process of photosynthesis, plants use energy from the Sun to convert carbon dioxide and water into glucose and oxygen. These products are, in turn, used by the plant or animals that eat the plant during cellular respiration to produce ATP.
ATP molecules store cellular energy. When phosphate groups are removed and molecules of ADP are formed, energy is released. This energy can be used to performcellular work.osmosis.electron transport.diffusion. - 11. Multiple ChoiceDuring photosynthesis, plants capture light energy from the Sun to break the bonds in reactants, such as carbon dioxide and water, and form carbon-containing molecules, such as glucose. The carbon-containing molecules can then be usedto produce inorganic compounds, such as sulfuric acid.to assemble larger molecules, such as DNA, proteins, and fats.to synthesize essential amino acids.all of these
- 12. Multiple ChoiceIn order to function properly, cells must perform many reactions. Metabolism is the sum of all the chemical reactions in an organism. During metabolism, ATP
I. is broken down to fuel chemical reactions.
II. is created by chemical reactions.
III. is shuttled from one cell to another.I, II, and IIII and II onlyI and III onlyIII only - 13. Multiple ChoiceWhich of the following are products in the process of photosynthesis?carbon dioxide and waterglucose and oxygenglucose and watercarbon dioxide and oxygen
- 14. Multiple ChoiceWhich of a cell's organelles releases energy stored in food?chloroplastslysosomesmitochondriaendoplasmic reticulum
- 15. Multiple ChoiceWhich of these would increase the rate of photosynthesis and lead to the production of more glucose?increase in available sunlight and available carbon dioxidedecrease in available sunlight and available carbon dioxideincrease in available sunlight and decrease in available carbon dioxidedecrease in available sunlight and increase in available carbon dioxide
- 16. Multiple ChoiceThe main result of photosynthesis isglobal warming.food production.carbon dioxide production.decreased atmospheric oxygen.
- 17. Multiple ChoiceDuring cellular respiration, every living thing in this food web uses ______ gas and releases ______ back into the environment.carbon dioxide:oxygenoxygen:carbon dioxidecarbon dioxide:hydrogencarbon dioxide:water vapor
- 18. Multiple ChoiceThe by-products of cellular respiration includeenergy and oxygen.glucose and oxygen.carbon dioxide and water.glucose and carbon dioxide.
- 19. Multiple ChoiceWhen a muscle cell demands energy to contract, what happens to ATP?ATP makes more ATPATP is hydrolyzed and turned into ADPATP is phosphorylatedATP is shuttled to the mitochondria
- 20. Multiple ChoiceATP is considered to be an energy carrier molecule. Where is the energy actually located in this molecule?attached to the phosphate groupin the bonds between phosphate groupsattached to the nucleotidebetween the sugar and the phosphate
