Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the reaction mechanism?Acts as an electrophilic phosphorylating agent, activating phosphate mono-esters for nucleophilic attack
2. What is the role in abiogenesis?Hypothesized to be critical intermediates in the prebiotic polymerization of nucleotides
3. Why do scientists think phosphorimidazolides helped life start?They can link nucleotides together in water, which could build the first RNA and DNA strands that carry genetic information.
4. How do phosphorimidazolides help enzymes make ATP?They activate a phosphate group so it can be easily transferred, forming the high‑energy bonds that store energy in ATP.

Organophosphorus compound: A chemical compound containing a carbon-phosphorus bond or a phosphorus-heteroatom bond.
Electrophilic phosphorylating agent: A substance that readily transfers a phosphoryl group to electron-rich molecules.
Abiogenesis: The natural process by which life arises from non-living matter, such as simple organic compounds.
