Enzymes are proteins produced by the body to do a particular job. The pancreas produces amylase to break down the carbohydrates in food into simple sugars. The pancreas makes lipase to digest fats into fatty acids. Sugars and fatty acids can then be absorbed by the small intestine.
It is a gas. Answer: Helium can be in any state (solid,liquid or gas) depending on its pressure and temperature. At 2.5 MPa:
Liquid helium can make up 30% of the cost of some low-temperature physics projects, so volatile prices complicate budgeting for multi-year grants. The high price of helium may have one silver lining: it has spurred researchers to think more about how to conserve the gas.
