Nitrite reductase in biology

Welcome to today's lecture on nitrite reductase in biology. Before we dive into the details, let's understand the broader context: the nitrogen cycle. Nitrogen is a vital element for all living organisms, as it is a key component of proteins, nucleic acids, and other essential molecules. However, atmospheric nitrogen (N2) is relatively inert and cannot be directly utilized by most organisms. This is where the nitrogen cycle comes into play, facilitating the conversion of nitrogen into various forms that can be readily used by living organisms.
