Also to know is, did the lactase enzyme show specificity?

- No, because only lactase can break lactose down, and sucrose has a special enzyme, as well, called sucrase, that breaks it down into glucose and fructose. - Usually enzyme specificity is caused by the enzyme's substrates, and this remains the case for this lab as well.

Beside above, what is meant by enzyme specificity? The ability of enzyme to bind with specific substrate or catalyze a specific set of chemical reactions,is called "Enzyme Specificity". Some enzymes have an intrinsic property of binding with only one substrate and catalysing a single reaction. This property is called "Absolute Specificity".

People also ask, is lactase an enzyme?

Lactase is an enzyme produced by many organisms. It is located in the brush border of the small intestine of humans and other mammals. Lactase is essential to the complete digestion of whole milk; it breaks down lactose, a sugar which gives milk its sweetness.

Why a glucose test strip may be used to determine the enzymatic activity of lactase?

The glucose test strip may be used to determine the enzymatic activity of lactase because lactase is an enzyme for digestion that is a catalyst for the breakdown of lactose. 2. In this exercise, five reactions were performed. Of those reactions, two were negative controls and one was a positive control.
