Heterocysts are Specialized Cells That Undergo

Question

Heterocysts are specialized cells that undergo
A) oxidative phosphorylation.
B) photophosphorylation.
C) nitrogen fixation.
D) lysine decarboxylation.

Accepted Answer

Heterocysts are specialized cells found in some filamentous cyanobacteria that can fix atmospheric nitrogen into ammonia through a process called nitrogen fixation. This process is essential because nitrogen is a necessary nutrient for many organisms, but atmospheric nitrogen cannot be directly used by most organisms. Therefore, heterocysts play an important role in the global nitrogen cycle. Heterocysts do not undergo oxidative or photophosphorylation or lysine decarboxylation.
