Document Summary

According to their theory, molecules gathered in the shallow waters of ancient oceans to form a complex solution called a prebiotic soup: mid size building block molecules linked to form the types of large molecules found in cells today, including proteins, nucleic acids, and complex carbohydrates, life became possible when one of these large, complex molecules made a copy of itself. Protein function: they are crucial to most tasks required for cells to exist, tasks including: catalysts): catalysis: catalyze chemical reactions through enzymes (proteins that act as, defence: antibodies attack and destroy viruses and bacteria that cause disease. body. cell itself, movement: motor proteins and contractile proteins are responsible for moving the, signalling: involved in carrying and receiving signals from cell to cell inside the, structure: structural proteins make up body components such as fingernails and, transport: allow particular molecules to enter or exit cells and carry specific hair. compounds throughout the body.
