Question

which molecule would be the most affected by limited nitrogen?
myofibrillar proteins in muscle
glucose molecules in starch
fat molecules surrounding organs
cellulose molecules in plant cell walls

Explanation:

Proteins contain nitrogen in their amino - acid structure. Myofibrillar proteins in muscle are proteins. Glucose (starch is a polymer of glucose), fat, and cellulose (a polysaccharide) are made up of carbon, hydrogen, and oxygen only. So, limited nitrogen would most affect the synthesis or structure of proteins.

Answer:

myofibrillar proteins in muscle
