Signal molecules bind to specific receptor proteins on the outside surface of the plasma membrane. This triggers a chain reaction of events that passes the signal to molecules inside the cell
Wrong way around. Atoms join together to create molecules. These molecules then join other molecules to create cells.
Yes, it is true: all chemical reactions create new molecules of compounds.
Pepsin is an enzyme that is produced in the stomach. It splits protein molecules in order to create proteoses and peptones.

Molecules that create problem are chlorine and fluorine. They deplete ozone.

They create molecules. If the atoms joined together are from different elements they create polar molecules.
Yes, it is true: all chemical reactions create new molecules of compounds.

The number of collisions with enough energy to react increases.

depend on if Europa have the appropriate environment necessary to create strings of molecules, because you need molecules to create life.
Ribozymes are RNA molecules that can act as enzymes; that is, catalyze covalent changes in the structure of substrates (most of which are also RNA molecules). Simple answer without Ribozymes we have no information or tools to allow us create blueprints for DNA or any structure of life.
Yes, that is how they attract to each other to create molecules.
