We often think of animals using oxygen and glucose for cellular respiration and producing carbon dioxide. Similarly, we might think of plants using carbon dioxide and sunlight for photosynthesis and ...

This process, called photosynthesis, is essential to the global carbon cycle and organisms that conduct photosynthesis represent the lowest level in most food chains (Figure 1). Most living things ...

In photosynthesis, light energy is converted into chemical energy which is stored in the sugar molecules produced. This stored energy is then available to the plant cells to use.

Hydrogen and ATP are both transferred to the second stage of photosynthesis. Some of the oxygen produced can be used by the mitochondria of plant cells for aerobic respiration. Most oxygen ...
