Summary Introduction
Archaea can be categorized into six groups based on morphological and physiological differences. However, Bergey’s manual of systemic bacteriology, a taxonomic organization divides archaea into two phyla Crenarchaeota and Euryarchaeota. There are three types of carbon fixation that have been characterized in archaea. This includes the reductive acetyl-CoA pathway, dicarboxylate/4-hydroxybutyrate cycle (DC/HB), and the 3-hydroxypropionate/4-hydroxybutyrate cycle (HP/HB). The dicarboxylate/4-hydroxybutyrate cycle (DC/HB) is an autotrophic pathway, which occurs commonly occurs in two Crenarchaeota family includes, Desulfurococcales and Thermoproteales.

- There is a rare microalga that has a promising future as a producer of a new type of biofuel. After research in the lab, it is found that it is having a difficult time propagating outside of its native environment, and it is identified that this is an issue with its respiration pathway. Overall ATP production is around half of expected,and you find that glycolysis isn’t producing any net ATP molecules and only one molecule of NADH. Question: Assuming that the respiration pathway is similar to other prokaryotes, where would you expect to find a nonfunctional mutation in this pathway? What is the reason for this? What could a growth strategy be that can better support this rare bacterium until you can come up with a long-term solution?arrow_forwardWhy is it necessary to lyse the chloroplasts? 1.DCPIP passes easily across the intact chloroplast membrane and the thylakoid membrane, so electron transport could not be reliably measured 2.DCPIP passes easily across the intact chloroplast membrane, but can't get into the thylakoid, so electron transport could not be reliably measured 3.DCPIP cannot easily pass across the intact chloroplast membrane, so electron transport across the thylakoid membrane could not be reliably measuredarrow_forwardThe light reactions of photosynthesis take place in the thylakoid disk the outer membrane of the chloroplast the stroma of the chloroplast cytoplasm of the host cellarrow_forward
