Photosynthesis / Cellular Respiration and the Carbon Cycle

What is energy stored in chemical bonds and released through chemical reactions?

• Chemical Energy

• Molecule

• Radiant Energy

• Carbon Dioxide–Oxygen Cycle

What is a sugar composed of six carbon atoms that is the preferred energy source for most cells; produced by photosynthesis?

• Glucose

• Photosynthesis

• Carbon Dioxide

• Cellular Respiration

What is the simplest unit of a chemical compound that can exist, formed when two or more atoms join together chemically?

• Molecule

• Radiant Energy

• Carbon Dioxide–Oxygen Cycle

• Oxygen

What is a chemical reaction during which plants convert radiant energy from the Sun to chemical energy; the reaction converts carbon dioxide and water into sugar (glucose) and oxygen?

• Photosynthesis

• Carbon Dioxide

• Cellular Respiration

• Chemical Energy

What is energy from the Sun that reaches Earth as visible light, ultraviolet radiation, and infrared (heat) radiation?

• Radiant Energy

• Carbon Dioxide–Oxygen Cycle

• Oxygen

• Glucose

What is a gas that is a natural component of the atmosphere; produced by cells during cellular respiration and used by plants and other organisms for photosynthesis?

• Carbon Dioxide

• Cellular Respiration

• Chemical Energy

• Molecule

What is the movement of carbon dioxide and oxygen on Earth by the processes of respiration and photosynthesis?

• Carbon Dioxide–Oxygen Cycle

• Oxygen

• Glucose

• Photosynthesis

What is the process of obtaining energy from the breaking of chemical bonds in nutrients?

• Cellular Respiration

• Chemical Energy

• Molecule

• Radiant Energy

What is a gas produced by plants during photosynthesis that animals use for respiration?

• Oxygen

• Glucose

• Photosynthesis

• Carbon Dioxide

• How are photosynthesis and cellular respiration related?

• They are the same process but in different organisms

• Photosynthesis uses sunlight to make food; respiration breaks food down for energy

• Both processes only happen at night

• Cellular respiration produces sunlight for photosynthesis
