Correct Answer - Option 3 : Both 1 and 2
  • Enzymes are proteins that act as biological catalysts (biocatalysts).
  • Catalysts accelerate chemical reactions.
  • The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products.
  • Almost all metabolic processes in the cell need enzyme catalysis in order to occur at rates fast enough to sustain life.
  • The study of enzymes is called enzymology and a new field of pseudoenzyme analysis has recently grown up, recognising that during evolution, some enzymes have lost the ability to carry out biological catalysis, which is often reflected in their amino acid sequences and unusual 'pseudo catalytic' properties.
  • Food processing is the transformation of agricultural products into food, or of one form of food into other forms.
  • Food processing includes many forms of processing foods, from grinding grain to make raw flour to home cooking to complex industrial methods used to make convenience foods.
  • Some food processing methods play important roles in reducing food waste and improving food preservation, thus reducing the total environmental impact of agriculture and improving food security.
  • Primary food processing is necessary to make most foods edible, and secondary food processing turns the ingredients into familiar foods, such as bread.
  • Tertiary food processing has been criticized for promoting overnutrition and obesity, containing too much sugar and salt, too little fiber, and otherwise being unhealthful in respect to dietary needs of humans and farm animals.
  • Amylase is a class of enzymes that degrade starch to glucose monomers.
