How do protists build necessary molecules?

Answer 1

The necessary molecules such as proteins are all built within the protist themselves by ordinary processes such as protein synthesis.

Answer 2

Protists build necessary molecules through processes such as photosynthesis, protein synthesis, and metabolism. They use raw materials such as carbon dioxide, water, and nutrients from their environment to synthesize molecules like carbohydrates, lipids, and proteins for energy, growth, and repair. Many protists have specialized cellular structures and organelles that help them carry out these biochemical processes efficiently.
