What kind of chemicals or factors can be used to break the intermolecular forces and disulfide bonds?
1. Please write the names of the main groups in which the proteins are classified according to their form and main function, and explain how a.a. distribution in proteins differs in these groups. Provide an example of a macromolecule or other complex structure representing each of the three types.
2. What kind of chemicals or factors can be used to break the intermolecular forces and disulfide bonds?
3. Define denaturation of proteins and list five different ways to denature a protein?
Q1. Complete the following for threonine, lysine, and tyrosine.
a. Draw the amino acid.
b. Circle the side chain.
c. Identify whether it is polar, nonpolar, acidic, or basic.
d. At what pH will it exist as a zwitterion?
e. What is the range of pH values when it will be positively charged?
f. What is the range of pH values when it will be negatively charged?
In tertiary structure, the hydrophobic amino acids tend to be:

A. Tucked away inside the protein.
B. Exposed on the outside of the protein.
C. Distributed randomly throughout the protein
D. All above
what type of intermolecular forces would be exhibited by the molecular C3H6 and C4H4
Which statement correctly describes hydrogen bonds that stabilises the protein structure?

A. Hydrogen bonds form between side chain atoms
B. Hydrogen bonds form between backbone atoms
C. Hydrogen bonds form between backbone atoms and side chain atoms
D. All of the above
How does protein form?
Explain how different bonds contribute into protein hierarchical structure.
Give one example which demonstrates four protein structures.
A mutant has shown the ability to break down starch into simple sugar and convert the simple sugar into a molecule named brooklynamide (bright red). After investigation, the scientists found out that the mutant has a gene insertion, Gene A, which transcribe and translate into Protein A; and Gene B for Protein B.

The scientists successfully extracted protein A. They hypothesized that Protein A is responsible for the breaking down of starch while Protein B is responsible for synthesizing brooklynamide. As part of the research team, you are tasked to design a simple experiment to prove the hypothesis.
After proving the above, scientists found out that protein B is, in fact, an enzyme and named it brooklynamide synthase. However, none of its properties was known. Design experiment to determine:
a) Enzyme’s optimal pH
b) Enzyme’s optimal temperature
c) Minimum enzyme concentration to reach maximum rate of reaction
Which factor of the genetic code makes organisms different from one another?
1 point
the number of base pairs
the order of the codons
the structure of the DNA
In the absence of oxygen, cells can produce small amounts of ATP from the anaerobic oxidation of glucose. This is not true for fatty acid oxidation. Explain why.
