Homework Answers
protein is the polymer of amino acids, that is, amino acids are monomer of protein.
elements used in the amino acids are Carbon, nitrogen, oxygen, hydrogen, sulfur ( sulfur is found in cysteine)
proteins functions are enzymes that catalyze the biological reactions.
and transporters on the membrane which transport molecules across the membrane are proteins.
Add Answer to:

Question 4 i. Choose 3 different diseases. For each disease, find one protein that is involved in the onset of the disease. Also, identify the function of that protein -- receptor, enzyme, etc. (if an enzyme, what does it catalyze). *Cannot be 3 types of cancer.* List this information as below for all 3 diseases: •Name of Disease •Protein Involved •Function of Protein ii. Compare the proteins that you have identified with the findings of another group. Determine if there...
