Unit 3: Cell Processes & Energy

In which way are photosynthesis and cellular respiration similar?

• Both processes destroy energy.

• Both create energy.

• Photosynthesis breaks down sugar while cellular respiration produces sugar.

• Both processes transfer energy from one form to another.

What is the correct equation for cellular respiration?

• oxygen + sugar -> carbon dioxide + water + Energy

• carbon dioxide + sugar + Energy -> carbon dioxide + water

• carbon dioxide + water -> oxygen + sugar + Energy

• carbon dioxide + water + Energy -> oxygen + sugar

What is important about cellular respiration?

• It produces energy from the sun.

• It forms sugar.

• It transforms sugar into a usable form of energy (ATP)

• Only plants perform this process.
