Answer:

Helicase

Explanation:

The DNA double helix is unzipped by the enzyme *HELICASE*. The enzyme breaks the hydrogen bond between the bases thereby causing the strands of the double helicase to unzip. The action of the helicase enzyme uses energy from ATP. The unzipping of the double helix does not occur in a swift move. One end of the DNA molecule with 5'-3' is opened up showing the antiparallel single strands. The end that is opened is termed INITIATION SITE of replication. The opening look like someone standing with legs wide open. The wide opening is called REPLICATION FORK. The single strands of the fork are usually unstable but their stability is maintained by the DNA-binding-proteins. Having opened the double helix, the replication would then continue in the 5'-3' direction of one of the two antiparallel single strands.

Pasta contains starch and thus contains more substrate and needs more enzyme to digest.

<h3>What is starch ?</h3>

A polymeric carbohydrate called starch, also known as amylum, is made up of a lot of glucose units connected by glycosidic linkages. The majority of green plants synthesize this polysaccharide as a form of energy storage. It is the most prevalent type of carbohydrate consumed by people worldwide and is present in significant proportions in common foods like wheat, potatoes, maize (corn), rice, and cassava (manioc).

Pure starch is a powder that is white, odorless, tasteless, and insoluble in alcohol or cold water. It is made up of the branching amylopectin and the linear and helical amylose molecules. Starch typically comprises 20 to 25% amylose and 75 to 80% amylopectin by weight, depending on the plant. Animals store their energy in glycogen, which is a more intricately branched form of amylopectin.
