A special group of chemical substances that are used to treat diseases caused by microbes are called?

Sunny_sXe [5.5K]

A special group of chemical substances that are used to treat diseases caused by microbes are called antibiotics.

An antibiotic is a chemical compound that is toxic to other bacteria and is produced by a living thing, usually a bacterium. In a complex environment like soil, organisms undoubtedly use antibiotics to regulate the growth of competing microbes. Soil microorganisms frequently produce antibiotics.

Bacteria and fungi are microorganisms that produce antibiotics that help prevent or treat disease. With the invention of penicillin in 1941, antibiotics gained widespread recognition. Since then, they have fundamentally changed how bacterial infections in humans and other animals are treated.

Glucokinase and hexokinase in glycolysis

Delicious77 [7]

<h2>Answer:</h2>

Glucokinase or Hexokinase is a enzyme used at the first step of glycolysis.

<h2>Explanation:</h2>

Glucokinase is a Isoenzyme(enzymes which differs in the sequence of amino acids but catalyses the same reaction) of Hexokinase .
Glucokinase (hexokinase D) is present only in liver and pancreas whereas hexokinase is present in all cells.
In first step of glycolysis i.e formation of glucose-6-phosphate from glucose is completed with the help of hexokinase. In this step a ATP molecule is consumed i.e ATP is converted to ADP

Result: Glucokinase and hexokinase are used in the first step of glycolysis.
