Photosynthesis and 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 uses carbon dioxide, while cellular respiration produces carbon dioxide.

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.

The diagram below shows the relationship between photosynthesis and cellular respiration and the organelles in which they occur. Which statement describes how photosynthesis and cellular respiration are interrelated?

• Oxygen is produced during cellular respiration and stored during photosynthesis.

• Carbon dioxide and water released by cellular respiration are used in photosynthesis.

• Photosynthesis releases the energy that is stored during the process of cellular respiration.

• Glucose is used during cellular respiration to produce food that is broken down during photosynthesis.

The graphs below show the changes in the relative concentrations of two gases in the air surrounding a group of organisms. Which process in the organisms most likely accounts for the changes shown?

• Cellular respiration

• Active transport

• Photosynthesis

• Evaporation

What is the chemical equation for photosynthesis?

• C6H12O6 + 6O2 -> 6CO2 + 6H2O + 6H2O

• 6CO2 + 6H2O -> 6O2 + 6H2O

• C6H12O6 + 6O2 -> 6CO2 + 6H2O

• 6CO2 + 6H2O -> C6H12O6 + 6O2

What are the reactants in the photosynthesis equation?

• oxygen and glucose

• carbon and water

• sodium and chloride

• carbon dioxide and water

The form of cell respiration that can take place in the absence of free oxygen.

• diffusion

• anaerobic

• aerobic

• osmosis

An organism that cannot create its own energy and must instead rely on consuming nutrients from other organisms.

• fermentation

• photosynthesis

• heterotroph

• autotroph

How do photosynthesis and cellular respiration work together?

• Photosynthesis makes glucose, and respiration uses it for energy.

• Photosynthesis makes carbon dioxide, and respiration uses it.

• Photosynthesis takes place in the presence of oxygen, and not carbon dioxide.

• Respiration happens inside cells, and Photosynthesis is outside the cell.

 

This is the chemical formula for a molecule of...

• oxygen

• carbon dioxide

• Glucose

• Water
