ETC - 10 facts


  • PS II & PS I need sunlight to get excited
  • Breaking apart of water molecules is called photalysis
  • PS II passes the electrons to plastoquinone (PQ) to transport the electrons to the cytochrome
  • B6F passes the electrons from the PQ and send it off to Plastocyanin to distribute it to PS I
  • PS II and PS I are photo systems which means they need sun to activate
  • PS I was discovered before PS II 
  • PS I passes its electron to ferredoxin and ferredoxin become reduced
  • NADP becomes negative after an electron passes through it, the positiv Hydrogen molecules bond with it making NADPH
  • ADP synthase bonds with Adenine and two phosphate molecules to form the adenine diphosphate (ADP); these begin spinning quickly allowing the excess hydrogen to exit the leaf. This movement of the hydrogen atoms causes the spinning to slow down.
  • The third phosphate bonds with the ADP to form ATP

Pig Dissection Review





This week my bio class was given the opportunity to dissect a fetile pig. This dissection was supposed to further our understanding of multiple body systems by giving us a more real view of what each body system actually looks like and where they are positioned throughout the body.


This is a picture of what the fetile pig looked like before the dissection begun. We were asked to determine the sex of the pig and came to understand that ours was female which gave us the thought of trying to find the ovaries.

We started by making an incision right under the rib cage to try and isolate liver, pancreas, kidneys, heart, lungs and ovaries





After opening up the pig's belly we began to isolate individual body parts
The Kidney
The Heart
cross section of the heart
An ovaries

The liver

After isolating all the parts in the belly of the pig Day 2 of the dissection began. This time our goal was to get the brain, lens and thyroid. Our group failed to locate the thyroid because everything looked the same, same color same texture we couldn't differentiate whether it was thyroid or fat or tissue.


Everything around the thyroid was the same color and texture so identifying the thyroid was too difficult a task for us


We began on the brain by cutting off the skin and splitting the skull




Our isolated brain was actually in excellent condition, our group took extra care not to damage it during the extraction process

Next, we began the extraction of the eyes and lens





After taking out the eye we had to cut it in half to get to the lens


Our final isolated lens
