2

How many bonds does Guanine and Cytosine have?

3

what component of the polypeptide is the next amino acid added forming the peptide bond?

carboxyl group

which protein structure involves peptide bonds between amino acids?

primary

The smaller the cell

more efficient diffusion

If hydrolysis stops, what movement across the cell membrane also stops with it?

Passage of a solute against its concentration gradient.

If the Antidiuretic hormone (ADH) is inhibited, what would be the result?
