Excited electrons are those which temporarily occupy a state higher than their ground state
The electron is excited if it is given extra energy, such as when a photon, or packet of light, absorbs it or if it collides with an atom.
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water
the test
tube must be swirled at a steady rate to facilitate the liberation of CO2 gas from the
solution
The reaction vessel should be submerged in the water bath as far as possible to keep the
entire contents at the temperature of the water bath. There is a valve attached to the rubber stopper that should be open
while attaching the assembly to the test tube, and then closed just before the start of data collection
