Primary is fast, short, and involves vigorous production of alcohol. Once primary fermentation is done, typically the beer is transferred into a new container for secondary fermentation. Secondary is long, slow, and allows more complex yeast metabolites to develop, which influences flavor.

The primary standard is the "titrant", which is the solution where in the concentration can be calculated and the volume is already known. On the other hand, the secondary standard is a solution wherein the concentration is not known yet.

The only difference being, in primary active transport, the energy is derived directly from the breakdown of ATP. In the secondary active transport, the energy is derived secondarily from the energy that has been stored in the form of ionic concentration differences between the two sides of a membrane.
