### Step-by-Step Solution: 1. **Understanding the Environment**: Antarctic waters are extremely cold, often below the freezing point of water. This poses a significant challenge for the survival of fish living in these conditions. 2. **Role of Antifreeze Glycoproteins**: To survive in such cold environments, many Antarctic fish have developed a special type of protein known as antifreeze glycoproteins. These proteins prevent the formation of ice crystals in their bodily fluids. 3. **Composition of Antifreeze Glycoproteins**: Antifreeze glycoproteins are primarily composed of cysteine-rich proteins. The structure of these proteins allows them to bind to ice crystals and inhibit their growth, thus preventing the fish's bodily fluids from freezing. ...
