Intro:
In this project, we learned how the body maintains itself through homeostasis and protein synthesis. Protein synthesis occurs because proteins die and need to be replaced. Our group specifically looked at the protein, myoglobin, focusing on its' genome sequence and structure, following with its' creation into a finalized protein. This process starts with the DNA sequence being transferred to an mRNA chain in the nucleus. Following, the mRNA chain then leaves the cytoplasm and enters a ribosome. tRNA connects with codons of the mRNA to form a protein chain in the ribosome. The folding of the protein chain which occurs in the endoplasmic reticulum completes the protein. Homeostasis is th body's ability to maintain a stable internal environment. Some examples of homeostasis are respiration, glucose, blood pressure and body temperature. My group focused on respiration or breathing rate at different levels of physical activity.

Concepts:
Homeostasis- The body's ability to maintain a stable internal environment
Myoglobin -a red protein containing heme that carries and stores oxygen in muscle cells
DNA - A self-replicating material used to store genetic information
mRNA /Messanger RNA - Tranports genetic material through a cell
tRNA/Transfer RNA - Translates genetic material into protein chains
Codon - A set of three nucleotides
Protien - A long chain of amino acids folded to perform a specific task
Amino Acid - An organic compound made up of a carboxyl group and an amino group
Protien Synthesis - The process of transferring genetic code into functioning protiens
Protien Folding - The process of folding an amino acid chain into a functioning protien
Nucleous - The organelle within a cell that duplicates and stores genetic material
RNA Polymerse - An enzyme that transcribes DNA into RNA
Ribosome - A molecular particle that translates RNA into a Protien
Cell -the smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane
Germ cell -a cell containing half the number of chromosomes of a somatic cell and able to unite with one from the opposite sex to form a new individual, a gamete
Haploid - having a single set of unpaired chromosomes
Diploid - containing two complete sets of chromosomes, one from each parent

Reflection:
Overall, I think these two project went very smoothly and were a success! I believe we had a great group dynamic and were able to collaborate ideas extremely well. In following projects, I want to learn to stay on task better and take more of a leadership role in order to help my groupmates. One of our pits was we had some human error during our homeostasis project; We forgot to press the time a few times and some of the test subjects would forget what number heart beat they were at. We retested and everything from there on in went very smoothly. One of our peaks during the photosynthesis lab was our groupmates ability to create a more understandable model of the myoglobin! I enjoyed these projects and would love to do similar ones in the future!
