WebChanges in temperature can affect the fluidity and permeability of cell membranes, which impacts cell structure and function. Below 0°C Increase in membrane rigidity. As the temperature drops to below zero, phospholipids lose much of their kinetic energy. Therefore, the membrane loses its fluidity which causes it to become very rigid.
WebNov 6, 2024 · What happens to cell membrane when temperature increases? Increasing temperature makes the membrane more unstable and very fluid. Decreasing the temperature will slow the membrane. The membrane will completely loose structure if the temperature goes beyond a certain point.
