Question 23 • Biology

Which molecule would be the most affected by limited nitrogen?

Answer
A
fat molecules surrounding organs
B
myofibrillar proteins in muscle
C
glucose molecules in starch
D
cellulose molecules in plant cell walls

Explanation

Nitrogen is a key element in amino acids, the building blocks of proteins. Myofibrils are made largely of proteins, so limited nitrogen would most directly affect their formation. Fats, cellulose, and glucose-based starch do not contain nitrogen as essential structural components.
