In photosynthesis, which gas is released as a byproduct?

In photosynthesis, which gas is released as a byproduct?

• A. Carbon Dioxide
• B. Nitrogen
• C. Oxygen
• D. Hydrogen

Answer: (C)

Light energy powers the splitting of water during photosynthesis. As water is split, oxygen atoms pair up to form O2 gas, which is released from the plant. The electrons and protons from water go on to generate ATP and NADPH, which are used to convert carbon dioxide into sugars. So oxygen is produced as a byproduct, while carbon dioxide is taken in to make sugar, and nitrogen isn’t released as a gas in this process.
