Photosynthesis

Photosynthesis

- It was developed 450 million years ago 


Chemiosmosis:  The movement of chemicals from high to low concentrations via semi permable membranes

Oxidized = Giving away electrons
Reduced= Gaining electrons

PSI needs P700 from the sun
PSII needs to receive P680 from the sun

Chlorophyll is a green pigment found in chloroplasts









Thylakoids store molecules that absorb  energy from the sun


Light-dependent reaction
traps solar energy and uses it to generate ATP and NADPH

light- independent reaction
Assimilates carbon dioxide to produce an organic molecule that can be used to produce biologically important molecules

Hydrogen= single proton


NADP exists to carry energy around

ADP spins very fast and the protons need to slow it down to form ATP

Fetal Pig Dissection

Fetal Pig Dissection 

Below abdominal cavity

Step 1

Identifying the sex of the pig
-Finding no opening around the umbilical cord and a small opening near the anus we discovered it to be female





Step 2
 

-Cutting below the abdominal cavity to reach the organs

- Many thick layers of skin and fat protected the pig's organs making it hard to cut open


Step 3

Delicately detaching the bottom layer of  skin from organs, as to not puncture organs


Step 4



Viewing the intestines and liver




Step 5



Removing the liver

Step 6




Removing the intestines

Step 7


Removing the stomach carefully as not to rupture it
we noticed the esophageal sphincter( small opening)

Step 8




Removing the pancreas
We found it to be surprisingly thin and short




Liver, intestine, pancreas


Step 9


After removing the intestines, stomach, liver,and pancreas; we were able to locate the kidneys located near the pig's back

Step 10

cross section of the kidney

Step 11


Removal of the Ovaries




Close up


Above the Abdominal Cavity

Step 12
Removing the brain










Step 13



Removing the eye
