<u><em>-What molecules get recycle to be used again during the process of photosynthesis?
</em></u>
During photosynthesis, plants use carbon dioxide and water to make sugar and oxygen. Some of this sugar, which is found in a variety of hydrocarbons, is recycled within the chlorophyll.
<u><em>-How would not having enough water molecules affect the light-dependent reaction in photosynthesis?
</em></u>
Without water, the light-dependent reactions would not have a supply of high energy electrons. Thus, without water, or not enough of it, photosynthesis would not be able to be preformed.
