Enzymes are organic catalysts which are protein in nature therefore they are sensitive to changes in temperature. Most enzymes have an optimum range of temperature between 35-40°c.
As temperature is increased, the optimum temperature is reached where the rate of reaction is maximum. When beef liver is boiled, hydrogen peroxide is not broken down because higher temperatures denature enzymes making them non effective.
No but they have cardiac chamber, compared with humans' four-chamber hearts, are a group of cells called nephrocytes that serve the same function as human kidneys
Ongoing effects include rising sea levels due to thermal expansion and melting of glaciers and ice sheets, and warming of the ocean surface, leading to increased temperature stratification.
