Unit 4 Test Cell Energy Corrections

Energy is released from ATP when

• a third phosphate group is added and a bond forms between the second and third phosphate group.
• adenine bonds to ribose.
• ATP is exposed to sunlight.
• the bond between the second and third phosphate is broken.

Plants gather energy with light-absorbing molecules called

• pigments
• thylakoids
• chloroplasts
• glucose

Where do the light-dependent reactions take place?

• in the stroma of the chloroplast
• within the mitochondrial membranes
• within the thylakoid membranes of the chloroplast
• in the outer membrane of the chloroplasts

Examine the graph. Which statement can best be concluded from these data?

• The respiration rate in both species is independent of both temperature and oxygen consumption.
• The respiration rate of midge larvae increases more rapidly than the rate for seabird ticks at all temperatures.
• As the temperature increases, there is an inverse relationship between oxygen consumption and the respiration rate in both species.
• As the temperature increases, the respiration rate in both species increases, with the rate for midge larvae being higher than that for seabird ticks at all temperatures.

Which of the following activities happens within the stroma of a chloroplast?

• Photosystem I absorbs light.
• ATP synthase produces ATP.
• The Calvin Cycle produces sugars.
• Electrons move through the electron transport chain.

The Calvin Cycle is another name for the

• light-independent reactions.
• light-dependent reactions.
• photosynthesis reaction.
• electron transport chain.

Which type of molecule is produced during photosynthesis?

• carbohydrate
• protein
• lipid
• nucleic acid

Identify the balanced chemical equation of aerobic cellular respiration.

• 6O2 + C6H12O6 → 6CO2 + 6H2O + ATP Energy
• 6O2 + C6H12O6 + ATP Energy → 6CO2 + 6H2O
• 6CO2 + 6H2O → 6O2 + C6H12O6 + ATP Energy
• 6CO2 + 6H2O + ATP Energy → 6O2 + C6H12O6

Which process does NOT release energy from glucose?

• glycolysis
• photosynthesis
• fermentation
• cellular respiration

Which of the following is one of the ways that cellular respiration and photosynthesis are opposite processes?

• Photosynthesis releases energy, and cellular respiration stores energy.
• Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back.
• Photosynthesis removes oxygen from the atmosphere, and cellular respiration puts it back.
• Photosynthesis consumes glucose, and cellular respiration produces glucose.
