Which of the following is NOT a function of bioinformatics?

Bioinformatics is a field that merges biology, computer science, and information technology to analyze and interpret biological data, particularly at the molecular level. It plays a crucial role in various areas, such as genomics, proteomics, and systems biology, by utilizing computational tools and algorithms.

Analyzing protein structure, comparing genomic sequences, and handling large data sets of genomes are all integral functions of bioinformatics. These activities involve using computational methods to understand the complexity of biological data, enabling researchers to uncover insights about genetic information, protein interactions, and evolutionary relationships.

On the other hand, examining cellular respiration predominantly involves biochemical pathways and processes that occur within living cells rather than the computational data analysis typically associated with bioinformatics. Cellular respiration focuses on how cells convert chemical energy from nutrients into ATP, a metabolic process that is generally studied through experimental and biochemical approaches rather than through bioinformatics. Thus, this option represents an area outside the primary scope of bioinformatics functions.
