Hexokinase is an enzyme involved in the phosphorylation of hexose (five carbon sugar). It speeds the process on adding a phosphorus to the sugar.

Yes,it is an example of non protein enzyme.


What is hexokinase?

Hexokinase is an enzyme that catalyzes the first step in glucose metabolism by phosphorylating glucose to form glucose-6-phosphate. This enzyme plays a crucial role in maintaining glucose homeostasis and energy production in cells. There are different isoforms of hexokinase that are found in various tissues, each with specific functions and regulatory properties.

What substrate is converted into glucose 6 phosphate by the enzyme hexokinase?

Glucose is the substrate that is converted into glucose 6-phosphate by the enzyme hexokinase. Hexokinase catalyzes the phosphorylation of glucose to glucose 6-phosphate in the first step of glycolysis.


Why does the structure of a protein or enzyme determine its function?

Is an enzyme an example of a eukaryotic cell?

No. An enzyme is a molecule, specifically a protein, that catalyzes a chemical reaction.


Why does heating up a protein such as an enzyme cause it to lose function?

Heating up a protein, such as an enzyme, causes it to lose function because the increased temperature disrupts the weak bonds that maintain its three-dimensional structure. This denaturation alters the enzyme's active site, preventing it from binding to its substrate effectively. As a result, the enzyme can no longer catalyze reactions, leading to a loss of function.

The level of protein structure primarily involved in determining enzyme activity is the?

The level of protein structure primarily involved in determining enzyme activity is the tertiary structure. This three-dimensional arrangement of the protein allows for the correct positioning of active sites and substrates, facilitating the catalytic function of the enzyme. Changes in the tertiary structure can significantly affect enzyme activity, potentially leading to loss of function.


What does it mean when the enzyme becomes denatured?

An enzyme is a folded protein. When this folded protein becomes denatured, it essentially stops working. It can not function due to high temperatures or wrong pH.
