Explanation:

At pH 2 the net charge of the R groups of all the amino acids that comprise the peptide in question would be positive. This happens because of the high content of protons in a solution of pH 2, a value that is below the isoelectric point of all the amino acids.

<h3>How did eukaryotic cells develop mitochondria and chloroplasts?</h3>

Chloroplasts and mitochondria most likely developed from engulfed bacteria that once existed as autonomous organisms. An aerobic bacterium was eventually swallowed by a eukaryotic cell, which later established an endosymbiotic bond with the host eukaryote and gradually transformed into a mitochondrion.
