    Q:

    		 Phospholipids and fatty acids, and their degree of saturation, have far-reaching implications for membrane transport and fluidity. Which of the following is a correct statement?
    		 

    A

    		 A saturated fatty acid has more double bonds than an unsaturated fatty acid

    B

    		 A species in a cold environment will tend to have more double bonds in the fatty acids of their phospholipids compared to a species in a warm environment

    C

    		 A species in a cold environment will tend to have less double bonds in the fatty acids of their phospholipids compared to a species in a warm environment

    D

    		 If the proportion of double bonds in a phospholipid increases, the fluidity of the membrane will decrease
