Tues-Day 1
AP Chem - took the unit exam on the Quantom Atom.
Look for the AP Chem Thanksgiving Assignment posted on Edline, and due on Monday.
Bio - we began our new unit: Photosynthesis and Respiration, by seeing the inter-relationship of these two processes. We defined the types of organisms that can perform photosynthesis as "autotrophs" i.e. self-nutrition suppliers, and the organisms that cannot do so as "heterotrophs" i.e. obtain nutrients by consuming other organisms.
We looked at the net chemical equation for both photosynthesis and aerobic cellular respiration, seeing that these reactions are basically the reverse of each other. In terms of energy, in photosynthesis, light energy is transformed to the chemical energy in ATP, which then provides the energy for making glucose from water and carbon dioxide. In aerobic cellular respiration, the energy stored in glucose is extracted and temporarily stored in the bonds in ATP, but ultimately the energy in ATP is released whenever the cell does any energy-requiring process.
