Exercise Science Assignment - Movement of Muscles Video

I did this project with Harsh and Gurkirat, our video as well as our chart is on Harsh's blog.

Stomach Vary in the Animal Kingdom

Everybody knows that humans have only one stomach which is apart of the digestive system however, it is not the same for certain animals.  For example, cows, giraffes, deer, and countless more animals have stomachs with multiple compartments as a result they have four chambered stomachs which help them with their digestion.  While other animals such as seahorses have a different digestive root, the food goes straight from their esophagus to their intestines.  I choose this topic because until now I thought every animal had one stomach.  After reading this article, I wonder how animals similar to seahorses break down their food?

Protein Lab

1.  A peptide bond is found in the primary structure between the amino acids.

2. The secondary structure forms because of polar peptide bonds between the amino acids.

3. The interaction between the different R groups which are basically amino acids create the tertiary structure.

4. Two or more polypeptides which are stuck together create the quaternary structure.  My protein shape looked differently than everybody else's proteins because everybody had different R groups therefore the interaction between their amino acids will cause the shapes to be different.

5. My protein would not have the same shape if I changed the primary structure because the interaction of the R groups would be different.

6. The highlighted parts represent the different R groups and this picture shows that the amino acid structure is not as straightforward as shown on our notes
  


This is the picture of my protein at the final stage.
