what product of photosynthesis is used in cellular respiration

The main product of photosynthesis that is used in cellular respiration is glucose (C₆H₁₂O₆) , along with the oxygen (O₂) that is produced.

Quick Scoop

• Photosynthesis makes:
  • Glucose, a high-energy sugar the cell can store or use as fuel.

* Oxygen gas, released as a by-product into the atmosphere.

• Cellular respiration then:
  • Uses that glucose and oxygen as reactants to make ATP (usable energy), plus carbon dioxide and water.

So the direct answer to “what product of photosynthesis is used in cellular respiration?” is:

• Glucose is the key fuel molecule used to release energy in cellular respiration.

• Oxygen produced by photosynthesis is also a crucial reactant for aerobic cellular respiration.

In simple terms: chloroplasts make the glucose and oxygen, and mitochondria burn that glucose with oxygen to power the cell.

TL;DR: Glucose (and also oxygen) made in photosynthesis are the products that cells use in cellular respiration to make ATP.
