Fri-Day 1
Bio 3/6- GREAT NEWS!!! Due to scheduling considerations, the Photosynthesis/Cellular Respiration exam date has been changed to NEXT THURSDAY, December 10. So, the unit hw will be due on TUESDAY, December 8 (it pays to read the blog!).
We discussed the two types of anaerobic respiration/fermentation: alcohol fermentation and lactic acid fermentation. Both of these types of fermentation can extract a small amount of energy from a glucose molecule and convert it to the energy stored in 2 (TWO) ATP molecules. That's it.
We then discussed the much MORE efficient, energy-extracting form of respiration that uses oxygen in the final steps of the process: AEROBIC RESPIRATION, which generates 36 (THIRTY SIX!) ATP overall per ONE glucose molecule respired.
AP Chem- we reviewed and emphasized the importance of Zeff, PEL of the electron(s) of interest, and electron-electron repulsion in the valence shell as we explained electronegativity, typical/stable ions of a given metal or nonmetal, and successive ionization energies/predicting the number of valence electrons in an atom.
PRACTICE writing and DRAWING these explanations of periodic trends and ANY anomalies to these trends that we discussed.
There are plenty of practice problems/tests as well as very good tutorials on Blackboard.
