Pre-Lab 10/14
1. Energy enters the living world by the sun.
2. In plants the pigment molecules absorb energy from the sun to power chemical reactions
and they absorb specific wavelengths of visible light to provide the energy required for
photosynthesis.
3. The process of chromatography separates molecules because of the different solubility
of the molecules in a selected solvent.
4. When the stomach digests food, the carbohydrate in food breaks down into another type
of sugar, called glucose. The stomach and small intestines absorb the glucose and then
release it into the bloodstream.
5. ATP captures chemical energy obtained from the breakdown of food molecules and
releases it to fuel other cellular processes.
