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

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
