Question

A) describe the role of hydrogen bonding (H bonds) in protein secondary structure, support using diagrams

describe the mechanism of a named secondary messenger in cell signalling. Support using diagrams

Answer 1

Hydrogen bonds are formed between parts of the polypeptide backbone and help maintain local folding, aka secondary structure. There are two main types of secondary structures, alpha-helices and beta-sheets.

For your second question, you did not provide the name of the secondary messenger, so I cannot help.
