Fetal Pig Dissection Discussion
The fetal pig dissection was very beneficial in helping me understand where all the body parts are located. I was very surprised about how big the liver was. Also, the liver was extremely dark in color, which was interesting as well. I was surprised about how the crammed the large and small intestines were in the abdomen. The fetal pig links together all the units of this course, it sums it up. The lab showed the digestive system,reproductive system, and circulatory system. Being able to see all of this "live" is really beneficial to me absorbing all of the information.

digestion question
Q: Why do we burp?
A: We burp because it is our bodies way of releasing air. When we eat or drink too fast or chew with our mouths open you often will burp more. This is because our stomach already has gases in it and when the extra air enters the stomach it needs to exit, thus we burp to release the extra air.

my marks
I believe that my mark reflects my work habits well. I have been keeping up with my homework which is why my mark is so high. I think that as long as I continue to keep on top of things I should be able to hold on to and improve this mark. The one area that I could work on is my preparation for quizzes. I just need to spend a little longer studying and I should be able to improve my mark very easily. yay bio 12:)

Lipid Synthesis
LIPID SYNTHESIS
Lipid Synthesis
The smooth ER has functions in multiple metabolic processes, including synthesis of lipids and steroids, metabolism of carbohydrates, regulation of calcium concentration, drug detoxification, attachment of receptors on cell membrane proteins, and steroid metabolism. Smooth endoplasmic reticulum is found in a variety of cell types (both animal and plant), and it serves different functions in each. The Smooth ER also contains enzymes which converts into glucose. The Smooth ER has tubules and vesicles that branch forming a network.
The vesicles that leave the rough endoplasmic reticulum are transported to the cis face of the Golgi apparatus, where they fuse with the Golgi membrane and empty their contents into the lumen. Once inside the lumen, the molecules are modified, then sorted for transport to their next destinations.
The Golgi apparatus, then sorts the vesicles for their journey so on.

Yay Photosynthesis
PHOTOSYNTHESIS
CHLOROPLAST
This guy which is only found in plant contains Chlorophyll. Cholorphyll is the green pigment in the cholorplast which captures the solar energy required for photosynthesis. The cholorplast also contains and inner and outer membrane as well as stoma, lamella, and granum.
The process of photosynthesis looks like this : 6CO2+6H2O+light ----> C6H12O6+6O2
and like this:
In photosynthesis, solar energy is changed to chemical energy. The chemical energy is stored in the form of glucose and is then later converted in to ATP

Cellular Breathing
CELLULAR RESPIRATION
THE MITOCHONDRIA : POWERHOUSE OF THE CELL
The mitochondria has a double bound membrane (inner and outer) found in the cytoplasm of eukaryotic and prokaryotic cells. The mitochondria consists of granules, cristaes, and DNA.
The mitochondria is the site of cellular respiration. What is cellular respiration? Cellular respiration is the process of converting chemical energy into ATP [ adenosine triphosphate ]. The chemical energy is produced through photosynthesis and then goes through a chemical reaction to become ATP.
What it looks like: C6H12O6 + 6O2
= 6CO2 + 6H2O + 36ATP

Labeling Labels
1) Nucleolus : produces ribosomes, contains RNA
2) Nucleus : contains chromatin(DNA and protiens) and RNA, stores genetic information, controlls cell division, and directs functioning of the cell
3) Ribosomes :made of RNA and protien, site of protien synthesis, reads RNA code and translates into amino acid sequence
4) Vesicles : transport materials around or out of the cell, membrane bound sac, formed from pinching off of membrane of E.R.
5) Rough E.R. : ribosomes on surface, network of tubules
6) Golgi body : stacked flat sacs, accept vesicles on one side and produce them on the other side, storage and packing of molecules, modifys protiens
7) Cytoskeleton : protien filaments and tubules throughout cytoplasm, maintains cell shape, transport of vesicles and organelles
8) Smooth E.R. : lack ribosomes, network of tubules, packages protiens for transport, detoxifies liver cells, large surface area, sythesizes lipid triglyerides and steroids
9) Mitochondria : production of ATP (site of cellular respiration), powerhouse of the cell, double bound membrane
10) Vacuole : membrane bound sac, larger than vesicles, storage
11) Cytoplasm : gel substance within the cell membrane that holds together all the organelles
12) Lysosome : contain digestive enzymes, garbage disposal, break down bacteria entering cell, intracellular digestion, manufactured by golgi body
13) Centrioles : made of microtubules, help in cell division
