Ch. 6 membranes & 16.3 viruses

Carp, unlike many other fish, can tolerate a wide range of temperatures. When carp are moved from a cold aquarium to a warm aquarium, the phospholipid fatty acids of their cellular membranes will become

• more saturated and with longer tails.

• more saturated and with shorter tails.

• less saturated and with longer tails.

• less saturated and with shorter tails.

• unchanged in their fatty acid composition.

Transmembrane proteins can also be classified as

• Peripheral membrane proteins

• Anchored membrane proteins

• Integral membrane proteins

• Proteoglycans
