The most regsengble explanation for this observation Is that A) plant cells are capable of having a much higher surface-to-volume ratio than animal cells. B) plant cells have a much more highly convoluted (folded) plasma membrane than animal cens. C) plant cells contain a large vacuole that reduces the volume of the cytoplasm.

Threonine (below and right) is another uncharged, polar amino acid. Illustrate the hydrolysis of a dipeptide that was made from these two amino acids. Be sure to write all involved reactants and products in the structural form like Serine, and as a proper chemical equation; e.g. reactant(s) - product(s). Your diagram of the dipeptide must show the N-terminal and C-terminal ends at opposite sides of the dimer molecule, and you need to indicate where the peptide bond is with an arrow/highlighter. „H C-N OH NH2 но CH — CH -с-соон он Harrow_forward
