How does the Antifreeze Protein in fish keep Arctic cod and Antarctic notothenioid from freezing?

Actually the genes for this kind of protein is widespread in nature occurring in both plants and animals, all kinds of animals including fish, insects, crustations. This would indicate that this protein occured early in evolution. This makes sense as the need to protect things that live in the cold and are mostly water would have occured throughout life's history on a planet where the temperature is and has been only a few degrees (remember even 500 degrees is not all that much astronomically) higher than the freezing point of water.

What are some adaptations fish in cold environments use to survive?
Fish that lived in cold water used an Antifreeze protein in their blood that prevent it from freezing. The antifreeze protein prevents that the blood that freezes stops the circulatory system and proteins and oxygen can no longer be in the cells and the fish would be death.
How do frogs get protein?
Frogs get protein by eating live prey.
What is the process by which a protein is constructed?
Protein Synthesis :), also known as TRANSLATION.
How much protein is in milo feed?
Milo runs at around 8.9% protein.
Which nutrient is found in plant protein foods and not in animal protein foods?
Fiber
Is fish that live in polar waters have a natural chemical antifreeze called glycoprotein?
It seems so. You can find more detail in the Wikipedia article on "Antifreeze protein".
What is the role of glycerol in the lysis buffer?
To protect protein during thawing and freezing
What is Anarctica's main food type?
There is no food grown on the Antarctic continent, but the Southern Ocean is the most productive ocean on earth in terms of the protein that lives there. The base of this food chain is Antarctic Krill -- Euphausia superba -- and it represents the main food type in that ocean: protein.

How would extreme cold reactions change if you ingest an antifreeze protein?
There would be no change at all as these are proteins, you would digest them. You would need to inject these proteins to have any chance of an effect and since we are warm blooded creatures we would die of hypothermia before the antifreeze protein would take action.
Why does freezing have an effect on amylase?
Freezing should have an effect on amylase. Amylase is an enzyme, which is therefore a protein, and has optimum conditions. Freezing it will severely slow it down, and I'm pretty sure will denature it, so yes it will completely reduce if not stop the effect of amylase. Freezing does not denature enzymes, heat does.
What kinds of dolphins live in the Antarctic or Arctic oceans?
There is no Antarctic Dolphin.However, The hourglass dolphin Lagenorhynchus crucigerdoes occupy the Southern Ocean, and is rarely seen. The Southern Ocean is the most protein-rich ocean on earth, providing in its short food chain sufficient protein for all the animals live in these waters.
Information on the Antarctic?
Antarctica is the highest, driest, windiest, darkest, coldest and iciest continent on earth. It is the heart of the Antarctic Region, which is polar and exists south of the Antarctic Circle. The Southern Ocean, which surrounds the continent, is the most productive ocean on earth, in terms of overall protein production. The whole of planet earth south of 60 degrees S -- i.e., most of the Antarctic Region -- is governed by the Antarctic Treaty, signed in 1960 by governments representing 80% of the earth's population.
What has the author Shing Leng Chan written?
Shing Leng Chan has written: 'Transcriptional regulation of the gene encoding the winter flounder antifreeze protein'
What did Captain Scott eat on his Antarctic expeditions?
Tinned and dried food was standard, with the main source of protein being pemmican: a 50/50 mix of lard and ground meat.
Which has the most wild life the Arctic or Antarctic?
If you're willing to include water in your definition, the Southern Ocean that surrounds Antarctica contains the most protein -- wildlife -- of any ocean on earth.
What producers live in Antarctica?
There are no producers in any food chain on the Antarctic continent, because it's too cold there for any food chain to grow.However, the Southern Ocean that surrounds the continent is the most productive food chain on earth in terms of the amount of protein produced there. The base of that productive, sea food chain is the Antarctic Krill -- Euphausia superba.The main producer in Antarctica is phytoplankton
