Fill-in the following paragraph:Biologists generally agree that the process of photosynthesis can be divided into two major reactions. These are often referred to as the light and dark reactions. During the light reaction molecules of (15)__________ are "split," producing hydrogen atoms and a gas called (16)__________. During this reaction, extra energy is stored in molecules of (17)_____________. The dark reaction requires no light because it is powered by the energy molecules made in the light reaction. A six-carbon compound known as (18)_______________ is formed during this reaction.
Fill-in the following paragraph:Biologists generally agree that the process of photosynthesis can be divided into two major reactions. These are often referred to as the light and dark reactions. During the light reaction molecules of (15)__H2O___ are "split," producing hydrogen atoms and a gas called (16)___O2____. During this reaction, extra energy is stored in molecules of (17)___ATP/NADPH____. The dark reaction requires no light because it is powered by the energy molecules made in the light reaction.
