Answer:

The biological significance is that it is the normal human body temperature and also the optimum temperature of the enzyme.

Explanation:

Enzymes are biological catalysts that speed up the rate of chemical reactions.
Enzymes catalyze specific reactions by working on a specific substrate to convert it into a product.
The rate of enzyme activity depends on several factors which include pH, temperature, substrate concentration, and enzyme concentration among others.
Enzymes work best at a specific pH and temperature known as optimum pH and optimum temperature respectively.
In this case, enzyme amylase works best at a temperature of 37° C which is equivalent to the normal human body temperature.

Which of the following is the correct formula for Ca2+ reacting with NO2??

mariarad [96]

Answer:

B. Ca(NO2)2

Explanation:

Ions (charged atoms) combine with one another to form stable ionic compounds. In this case, calicium ion (Ca2+) is said to react with NO2, which has a charge of -1 i.e. +1-1(2) = 1-2 = -1.

This means that calcium has a charge of +2 while nitrite ion has charge of -1, hence, when they combine, they exchange their charges, which become their subscript as follows:

Ca2+ + NO2- → Ca(NO2)2

Ca(NO2)2 is a stable ionic compound called calcium nitrite. Notice that it takes two atoms of NO2- to react with one atom of Ca2+.

Draw the structure of the neutral product formed in the reaction of dimethyl malonate and methyl vinyl ketone.

Dmitriy789 [7]

Answer:

Explanation:

The reaction between dimethyl malonate which is an active methylene group with an (∝, β-unsaturated carbonyl compound) i.e methyl vinyl ketone is known as a Micheal Addition reaction. The reaction mechanism starts with the base attack on the β-carbon to remove the acidic ∝-hydrogens and form a carbanion. The carbanion formed(enolate ion) attacks the methyl vinyl ketone(i.e. a nucleophilic attack at the β-carbon) to give a Micheal addition product, this is followed by the protonation to give the neutral product.
