The development of different cell technologies has led to changes in existing information. Which of the following is an example of a discovery that could cause such a change?

A discovery that reveals a new step in a metabolic pathway adds new information about how cells work and could require existing explanations to change. Confirming known water movement or reproducing earlier results supports existing information, while changing how a variable is measured does not necessarily change what is known biologically. The correct choice is an experiment that reveals a new step in a metabolic pathway.
