WebAs the temperature increases, the permeability of the cell-surface membrane also increases. This is because the proteins in the membrane denature as the heat damages the bonds in their tertiary structure. This creates gaps in the membrane so it is easier for molecules to pass through it. Conclusion and explanation of low temperatures WebA moderate change in ambient temperature can lead to vital physiological and biochemical adjustments in ectotherms, one of which is a change in fatty acid composition. When temperature decreases, the composition of membrane lipids (phospholipid fatty acids) is expected to become more unsaturated to be able to maintain homeoviscosity. ct angio machineWebJan 25, 2024 · When the cell is above body temperature cholesterol stabilizes the membrane and makes it more rigid, but at low temperatures cholesterol helps to make the membrane more fluid. ear related clue
