Neither ribonuclease nor myoglobin had quaternary sturucture why?

Ribonuclease and myoglobin is composed of only 1 polypeptide chain; as a result, they do not have quaternary structure. I am hoping that this answer has satisfied your query about and it will be able to help you, and if you’d like, feel free to ask another question.

the answer is d (apex) good luck : ))

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy
