Chapter 8, Problem 25RE

REFLECT AND APPLY Suggest a reason why the cell membranes of bacteria grown at $20°\text{C}$ tend to have a higher proportion of unsaturated fatty acids than the membranes of bacteria of the same species grown at $\text{37}°\text{C}$. In other words, the bacteria grown at $\text{37}°\text{C}$ have a higher proportion of saturated fatty acids in their cell membranes.
