What Are Photosynthesis and Respiration? - dummies

Essential question: Why do plants need sunlight to carry on cell respiration and photosynthesis?

How are photosynthesis and respiration related? | …

Respiration occurs in your cells and is fueled by the oxygen you inhale. The carbon dioxide gas you exhale is the result of a completed cycle of cellular respiration.

On the other hand, carbon dioxide and water, which are the products of cellular respiration, are the ingredients for photosynthesis.

How are photosynthesis and respiration related

Respiration consists of a complicated series of chemical reactions. In the first stage, glucose is oxidized, and the chemical potential energy of its bonds is transferred to the chemical potential bonds of an ATP molecule. The ATP molecule can then be transported throughout the cell where its stored energy is used to complete various tasks within the cell. This process releases carbon dioxide gas and water.

Only plants can photosynthesize, but both plants and animals depend on respiration to release the chemical potential energy originally captured through photosynthesis.
