Question
Which statement best describes what occurs during DNA replication? Which of the following choices illustrates the general pathway by which fats are catabolized? For the question(s) below, identify the type of reaction that occurs for each step of beta-oxidation. The second step of beta-oxidation is shown below. What type of reaction is this? For the question(s) below, identify the type of reaction that occurs for each step of beta-oxidation. The first step of 3-oxidation is shown below. What type of reaction is this?Explanation / Answer
25. A. The DNA double helix unfolds, and each strand serves as a template for the synthesis of a new strand of DNA. The remaining options hold true for transcription of mRNA, not for DNA replication.
26. A. Oxidation to acetyl CoA to citric acid cycle. Fatty acids are metabolized through beta oxidation. The process is not a hydrolysis since components of water are added to the fatty acid during its oxidation, and electrons are removed, so it is not reduction.
27. C. Hydratrion. One H is added to the second carbon and an OH is added to the third carbon to saturate the double bond between them.
28. a. Oxidation. Two hydrogens or electrons are removed from the fatty acid in this reaction
