A bacterium is suddenly expelled from a warm human intestine into the cold world outside (hey, it’s been a cold December!). Which of the following adjustments might the bacterium make to maintain the same level of membrane fluidity? Adaptation of Membrane Fluidity In Cold Temperature: A Bacterium’s Journey

Adaptation of Membrane Fluidity In Chilly Temperature: A Bacterium’s Journey

When a bacterium is immediately expelled from a heat human gut into the chilly world outdoors, it should make sure changes with the intention to preserve the identical stage of membrane fluidity. One of many changes the bacterium should make is a rise in fatty acid saturation of its membrane lipids. This is because of the truth that fatty acid saturation will increase membrane fluidity at low temperatures (Giorgio et al., 2019). As well as, the bacterium could incorporate extra unsaturated fatty acid molecules into its membrane, which may additionally enhance membrane fluidity (Chen et al., 2016). As temperature decreases, the bacterium should additionally alter its membrane composition with the intention to forestall the membrane lipids from forming a gel-like state. To attain this, the bacterium could enhance the focus of sphingolipids and ldl cholesterol in its membrane (Chen et al., 2020). It will cut back the possibilities of lipid-lipid interactions and end in elevated membrane fluidity. Furthermore, the bacterium might additionally enhance its focus of phospholipids, which may also help preserve membrane fluidity at low temperatures (Chen et al., 2021). Cont…
