I think its the first one
<h3>
Answer: E) carbon of the carboxyl group and the nitrogen of the amino group.</h3>
Explanation:
tyrosine and isoleucine are amino acids.
When they are condensed, they form a peptide bond which occurs between the carbon of the carboxyl group and the nitrogen of the amino group (OPTION E).
<u>Answer:</u>
<em>Polymers of amino acids can be both fibrous as well as globular protein. Hemoglobin is a globular but the collagen is the fibrous protein both being the amino acids.</em>
<u>Explanation:</u>
- <em>Soluble in water: </em>globular protein is soluble in water.
- <em>intermediate filaments:</em> fibrous protein
- <em>Insoluble in water:</em> fibrous protein is insoluble in water.
- <em>function as structural proteins in the cell:</em> fibrous protein.
- <em>some function as enzymes: </em>globular protein.
- <em>structure is somewhat spherical;</em> globular protein.
- <em>structure is rod-like:</em> fibrous protein
Answer:
They contain protein fibres that can contract when energy is available, making the cells shorter.
