Transcript of During the early part of World War II a brigade of French soldiers were trapped by a superior force...
During the early part of World War II a brigade of French soldiers were trapped by a superior force of German force and unable to escape. The French were without adequate food and virtually out of water for several hot September days.
When they finally escaped the encirclement, the soldiers retreated. They came across a farm with many bee hives and quickly removed the combs and ate large amounts of honey.
All but one perished within several hours. WHY??? (They did not die from enemy fire or bee stings.)
Organic Chemistry
Carbon• Living things are mostly made
of very few elements
• C H O N P S
• Carbon is the most useful
• Plants take in carbon from CO2 .
• Organic chemistry is the study of carbon compounds
• Vitalism vs. mechanism.
Carbon
Remember Miller?

ATP → ADP + energy.
