Answer:
100% of the water is part of the hydrological cycle.
Explanation:
The hydrological cycle is a cyclic process that occurs mainly in the biosphere; this hydrological cycle is in constant movement in the repetition of its cycle; it has different stages, among them the evaporation, condensation, precipitation, infiltration among others.
In the hydrological cycle, 100% of water enters, which is obtained mostly from the oceans; another percentage is extracted from glacier ice and groundwater, also acquires a small percentage of water from the atmosphere and freshwater. And the time of permanence of the water in the hydrological cycle depends on its quantity, so will be the days that it will remain.

Explanation:
A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes. Enzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too.
Enzymes perform the critical task of lowering a reaction's activation energy—that is, the amount of energy that must be put in for the reaction to begin. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily.
