Proteins are made from amino acids by the process of:
A. hydrolysis.
B. pinocytosis.
C. active transport.
D. dehydration synthesis.
Proteins are large chains of amino acids combined by dehydration synthesis, where by molecules join by removing water. Hydrolysis breaks down proteins into amino acids. Pinocytosis is a method of ingesting large insoluble molecules, and is a form of active transport.
