Some Species of Fish That Live in the Cold Waters

question 32

Multiple Choice

Some species of fish that live in the cold waters of the Arctic Ocean have evolved an "antifreeze" protein. Why might this protein be important to homeostasis?

• A)The protein might be involved in transporting water into fish cells during cold weather. The more water in the cell, the smaller the chance that ice crystals will form.
• B)The protein might prevent ice crystals from forming inside cells, which would prevent damage to the plasma membrane when temperatures are low.
• C)The protein might be involved in removing solutes from fish cells during cold weather. With fewer solutes in the cell, essential chemical reactions are more likely to occur.
• D)The protein might allow this species of fish to survive global warming by allowing it to carry out chemical reactions that would normally be prevented by warm temperatures.
