Explanation / Answer

32) Bacteria often contain extrachromosomal DNA molecules called plasmids that replicate independently of chromosomal DNA.

34) To explain the origin of eukaryotes, Lynn Margulis developed a theory named the endosymbiotic theory, in which respiring bacterium or phototrophic bacterium was internalized into a pre-eukaryotic cell.

35) There are two parts of metabolism: 1. Catabolic reactions are the enzyme-regulated reactions that release energy and building blocks for biosynthesis and 2. Anabolic reactions are the enzyme-regulated reactions that build complex organic molecules from simpler ones using energy and building blocks.

36) In many anabolic pathways, the final product can allosterically or competitively inhibit the activity of one of the enzymes earlier in the pathway (generally the first enzyme of the pathway). This type of regulation is called feedback inhibition.
