LIFESCI 2G03 Test 1 Questions and Answers Already Passed Question: What is the main function of enzymes in biological systems? Answer: Enzymes act as catalysts that speed up chemical reactions by lowering the activation energy required for the reaction to proceed. Question: How does the structure of DNA enable it to carry genetic information? Answer: DNA's double-helix structure, composed of nucleotide pairs (adenine with thymine and cytosine with guanine), allows it to store and...
