a marathon runner frequently becomes exhausted when they run

Homework due wed. Feb. 22 (10 points)-Biological Macromolecules; Prokaryotes/Eukaryotes Name: 4. The cell membrane of a newly discovered archaeal organism found living in a hot spring was found to be made up of approximately 95% saturated fatty acids and 5% unsaturated fatty acids. Another archaeal organism found growing in Antarctica was found to have 50% saturated fatty acids and 50% unsaturated fatty acids it its cell membrane, Explain why this is the case. da pandena s, avowth tempe Em oli an archae 5.

Solution

Answer 4: One of the factors that determine the composition of the cell membrane of archaeal organisms is temperature. Archaeal bacteria residing in the hot springs have the tendency that their cell membranes will melt with high temperature. In order to adjust in the high temperature environment, high amounts of saturated fatty acids are found because these fatty acids have higher melting points compared to unsaturated fatty acids and prevent the membranes to be liquid. On the other hand, the archaeal organisms found in the antartica where temperature is low, their membranes have a probability to form gel and stop functioning, in order their membranes to be fluid in nature they adjust themselves in the environment by introducing higher amounts of unsaturated fattty acids which have lower melting temperature and keep their membranes fluid in nature so that these cell membranes function normally.
