Which of the following best describes how the first large organic molecules on the early Earth may have been formed?
a)Enzymes catalyzed reactions between smaller organic molecules to form larger ones.
b)Heat energy became trapped in the atmosphere by greenhouse gases and was used as an energy source in the building of macromolecules. c)Lightning provided the energy needed for gases to react with each other and form amino acids.
d)Tidal flow and ocean currents helped mix molecules together so that they could react to build larger molecules.
