Which mechanism prevents ice crystal formation within cells during arctic ground squirrel hibernation?

💡 Explanation

When ground squirrels initiate hibernation in freezing conditions, antifreeze proteins bind to small ice crystals forming, preventing further crystal growth, thus protecting cellular structure. Therefore, antifreeze protein production prevents ice formation, rather than shivering, altered glucose, or increased respiratory rate which relate to thermogenesis, metabolism, or cooling respectively.
