The necessary molecules such as proteins are all built within the protist themselves by ordinary processes such as protein synthesis.
How are smaller molecule necessary for life
Most protists require water for survival as it is necessary for essential cellular processes such as respiration, digestion, and reproduction.

Hydrogen bonding is necessary for forming double-stranded DNA molecules.
The primary factor missing for billions of years that was necessary for protists to evolve was atmospheric oxygen. In order to grow and evolve, protists needed oxygen at a time when there was little in the atmosphere.
The two processes necessary to build or separate macromolecules are dehydration synthesis and hydrolysis. Dehydration synthesis involves removing water molecules to bond monomers together and form a larger macromolecule. Hydrolysis involves adding water molecules to break down a macromolecule into individual monomers.
How are smaller molecule necessary for life
Yes, anabolic reactions require energy to build complex molecules.
Protists can have either a cell wall, a cell membrane, or both. The presence of a cell wall in protists varies among different species and can be made of various materials such as cellulose, silica, or chitin. The cell membrane is common to all protists as it is essential for controlling the movement of molecules in and out of the cell.
Most protists require water for survival as it is necessary for essential cellular processes such as respiration, digestion, and reproduction.
All organisms use energy for metabolism, which includes the breakdown of molecules to release energy (catabolism) and the building up of molecules to store energy (anabolism). This process is essential for life as it allows organisms to obtain necessary nutrients and perform various functions to maintain their biological processes.

The primary factor that was missing for billions of years that was necessary for protists to evolve was oxygen in the atmosphere. Billions of years ago, the atmosphere was mostly made up of carbon dioxide, carbon monoxide, hydrogen, nitrogen, and water vapor.
