Summary
Photosynthesis stores energy in glucose and releases oxygen; respiration releases that energy and consumes oxygen.
In depth
Photosynthesis occurs in chloroplasts, using CO2 and water, producing glucose and O2; respiration occurs in mitochondria (and cytoplasm), consuming glucose and O2. Both use electron transport chains and chemiosmosis. Their equations are roughly reverses.
The processes mirror each other: photosynthesis builds, respiration breaks down. Together they cycle carbon through ecosystems.
Example: a plant at night respires but cannot photosynthesise.
Frequently asked questions
What is Photosynthesis vs Respiration?
Photosynthesis stores energy in glucose and releases oxygen; respiration releases that energy and consumes oxygen.
Which area of biology covers Photosynthesis vs Respiration, and how advanced is it?
Photosynthesis vs Respiration is one of the 53 topics in Metabolism & Bioenergetics. It is rated Beginner, so it suits learners who are starting out in biology. Related topics in this area include Cellular Respiration, Respiratory Equation, Glycolysis.
Can you give an example of Photosynthesis vs Respiration?
Plants do both; at the compensation point, rates are equal.
What should I learn before Photosynthesis vs Respiration?
Photosynthesis vs Respiration is a Beginner topic, so no earlier topic is required. Other Beginner topics in Metabolism & Bioenergetics that pair well with it include Metabolism, Anabolism and Catabolism, ATP.

How is Photosynthesis vs Respiration different from Cellular Respiration?
Photosynthesis vs Respiration: Photosynthesis stores energy in glucose and releases oxygen; respiration releases that energy and consumes oxygen. Cellular Respiration: The process of releasing energy from glucose to make ATP, using oxygen in the aerobic form. Read both side by side and note what each one explains.
How should I study Photosynthesis vs Respiration step by step?
First, read the summary and write the definition in your own words. Second, read the in-depth section and note any example. Third, compare it with Cellular Respiration and explain the difference aloud. Finally, take the Metabolism & Bioenergetics quiz and come back to this page for any question you miss.
