All chemical reactions that occur in the body are. metabolic processes what are the two types of metabolic reactions? Anabolism and Catabolism anabolism builds large molecules from simple ones; requires energy catabolism Process of breaking down complex materials (foods) to form simpler substances and release energy. anabolism provides for what two things? Cellular growth and repair What anabolic process is used to make polysaccharides, triglycerides and proteins. dehydration synthesis What process is used to decompose carbohydrates, lipid and proteins? catobolic process What is used to split the substances during the catobolic process? Water enzymes protein substances that speed up chemical reactions. cofactors A non-protein component that makes some enzymes active. Coenzymes organic molecules that act as cofactors example vitamins What factors alter enzymes? Heat, Radiation, Electricity, Chemicals, Changes in PH What regulates the metabolic pathways negative feedback adn limited number of regulatory enzymes Examples of enzymes Sucrase, lactase, protease, lipase dehydration syntheisis produces what? produces water enzymes are ---------specific. substrate what determines the active site of substrate? shape What do enzymes do? control the rate of metabolic reactions Enzymes jave the suffix --ase enzyme action-metabolic pathways each new substrate is the product of the previous reaction
