Modes of Nutrition

It is a biological process of providing or obtaining food that is necessary for growth and health. It includes many physiological processes - absorption, ingestion, assimilation, catabolism, excretion, etc. In biology, the science that deals with nutrition's physiological and chemical processes are called "nutritional science."

Read the following scenario and answer the associated questions. Hydrogen peroxide was added to a piece of potato and potatoes contain the enzyme, catalase. When hydrogen peroxide was added to the potato, bubbles appeared due to the presence of oxygen gas. The presence of the oxygen gas indicates that the catalase was breaking down the hydrogen peroxide into oxygen gas and water. If the hydrogen peroxide was removed and re-added to the potato, would bubbling occur again? Explain why or why not What do you think would happen if the potato in the above question was boiled before being placed into a container with hydrogen peroxide?
