Fittoniya [83]

<u>Chemical bonds between glucose molecules in starch that are easily broken by human </u><u>digestive enzymes </u><u>are called</u><u> alpha bonds.</u>

How is starch broken down into glucose?

  • When you consume starchy meals, an enzyme called amylase located in your saliva and small intestine breaks down the starches into sugars like glucose, maltotriose, and maltose.
  • Other enzymes, such as maltase, lactase, sucrase, and isomaltase, further break down these compound sugars into simple sugars.

What is alpha and beta bond?

  • The 1,4 alpha and 1,4 beta glycosidic linkages are the two different forms of glycosidic bonds.
  • When the OH on the carbon-1 is below the glucose ring, 1,4 alpha glycosidic bonds are created, whereas when the OH is above the plane, 1,4 beta glycosidic bonds are created.

Pepsi [2]

Answer:

<em>As scientists learned more about genetics and biochemistry , some organisms were moved out of existing kingdoms and into new ones.</em>

Explanation:

As the researches in the scientific world continued, scientists realized that there were, in fact, many genetic diversities present in organisms which were placed in the same groups. Hence, they realized that due to these differences these organisms should not be kept in the same group. As a result, the groups in the classification system increased.

Carolus Linnaeus just grouped organisms based on their features. But today, scientists classify organisms based on various perspectives such as the evolutionary history, genetic similarities etc.
