Haemoglobin is comprised of four polypeptides that interact to produce a functional molecule. This type of interaction between polypeptides is best referred to as:

Primary structure

Tertiary structure

Quaternary structure

Secondary structure

Protein structure

Some viruses have RNA as their genetic material. What type of bond joins the monomers of this nucleic acid together?

Glycosidic

Ester

Peptide

Phosphodiester

None, as RNA is single stranded.

What is the next step in this process?

Potassium pumped into cell, against its concentration gradient. Sodium-potassium pump

The protein simultaneously picks up sodium ions and they dislodge the potassium ions inside the cell.

Potassium ions are released into the cell.

Phosphorylation leads to a change in protein shape, reducing its affinity for potassium ions, which is released outside the cell.

The binding of potassium ions changes shape of the protein and results in their release outside the cell.

The binding of potassium ions changes shape of the protein and results in sodium ions binding simultaneously.
