An unchanged independent variable used for comparison is called a control variable.

It is unchanged by the reaction.
A control group is a group in an experiment that remains unchanged and is used as a baseline for comparison with the experimental group. It helps researchers determine the effect of the intervention being tested by providing a point of reference.
The positive degree of comparison is used. (That it, no comparison is made.)

Enzymes remain unchanged and available to catalyze multiple reactions. They are not used up in a reaction.

A constant in an experiment is something that remains unchanged throughout the experiment. It is typically used as a control or reference point for comparison to observe the effects of the manipulated variables. Examples of constants can include temperature, pH, time, or the type of equipment used.
A comparison using like or as is a simile. A comparison without them is a metaphor.
