Limited nitrogen availability would most significantly affect **myofibrillar proteins in muscle**.
This is because myofibrillar proteins, such as actin and myosin, contain a high proportion of nitrogen in their amino acid composition. Proteins are made up of amino acids, which include nitrogen in their structure. Therefore, in conditions of nitrogen limitation, the synthesis of these proteins would be hindered.
In contrast, glucose molecules in starch, fat molecules surrounding organs, and cellulose molecules in plant cell walls are not primarily dependent on nitrogen for their structure and function. Glucose and fats do not require nitrogen, and cellulose, while it is synthesized in plants, primarily derives its components from carbon, hydrogen, and oxygen, not nitrogen.
