He also went through what you had read in the book - and what you should have down in your directed reading - and we went over these TOGETHER on Friday and started to use out Photosynthesis models to "act out" photosynthesis.
A Really neat way to show you how the colors we SEE are actually what is being REFLECTED is in this YouTube Video:
And here is where the Photosynthesis Models Came in:
Light Dependent Reaction:
Water splitting:
Energy from the Sun - Causes electrons to get excited - Water that has entered via the roots.... Gets Split apart......(see next picture) |
DURING this time - Two energy carriers are created. Remember.... Energy is STORED in chemical bonds and RELEASED when bonds are broken. We used out brightly colored beads to represent our energy molecules:
NADP and ADP are in the chloroplast already. |
Another Phosphate is Added to ADP to create ATP. |
A Hydrogen ion is added to NADP to create NADPH |
Today's Daily Questions related to the what we have done so far with photosynthesis:
Then we went into the production of Glucose (IN A VERY simplified form)
The ENERGY required from this came from the transfer of a Phosphate group (the orange bead) and the removal of a H+ from the NADPH) |
I also made most of you listen to the annoying (but VERY accurate) rap as a wrap up....
