The molecule most affected by limited nitrogen is myofibrillar proteins in muscle, as they rely on nitrogen-containing amino acids for synthesis. Other options like glucose, fat, and cellulose do not depend on nitrogen. Therefore, limited nitrogen directly impacts muscle protein synthesis, essential for muscle function.

Limited nitrogen primarily affects the synthesis of myofibrillar proteins in muscle, which require amino acids containing nitrogen. Other options like glucose, fat, and cellulose do not rely on nitrogen for their structure. Hence, myofibrillar proteins are the most impacted by nitrogen limitation. ;
