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.
Protein
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.
Yes.
Hexokinase
Protein
Hexokinase binds to glucose and ATP at its active site, which is a specific region on the enzyme that facilitates the chemical reaction. The binding of glucose and ATP induces a conformational change in hexokinase, allowing for the efficient transfer of a phosphate group from ATP to glucose, forming glucose-6-phosphate. This process occurs in the cytoplasm of the cell, where hexokinase is primarily located.
No. An enzyme is a molecule, specifically a protein, that catalyzes a chemical reaction.
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.
by function is enzyme ... by structure is hormone
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.
