What reaction does the enzyme hexokinase catalyze?
First step of glycolysis- the phosphorylation of glucose to glucose-6-phosphate.
The process of glycogen to glucose?
Glycogen is a highly branched polymeric structure containing glucose as the basic monomer. First individual glucose molecules are hydrolyzed from the chain, followed by the addition of a phosphate group at C-1. In the next step the phosphate is moved to the C-6 position to give glucose 6-phosphate, a cross road compound. Glucose-6-phosphate is the first step of the glycolysis pathway if glycogen is the carbohydrate source and further energy is needed. If energy is not immediately needed, the glucose-6-phosphate is converted to glucose for distribution in the blood to various cells such as brain cells.
What percentage by weight of triglyceride molecule can be converted to glucose?
The glycerol backbone. The glyceol backbone undergoes metabolism to become glyceraldehyde-3-phosphate, which is one of the reactants in glycolysis. Two molecules of G3P becomes one molecule of glucose in a process that is the reverse of glycolysis called gluconeogenesis.
Is sucrose a substrate?
The Substrate for amylase are starch (amylose and Amylopectin), glycogen, and various Oligosaccharides.
What substrate would fit into the active site of maltase?
2 glucose
Glucose to glucose 6-phosphate. Irreversible. Hexokinase/gluckokinase. Requires ATP and Mg2?
Glucose to glucose 6-phosphate. Irreversible. Hexokinase/gluckokinase. Requires ATP and Mg2+
The enzyme hexokinase catalyzes the first step of glycolysis, and is crucial to initiating the process and preventing the initial substrate from easily traveling out of the cell (as its pre-reaction structure is membrane permeable)?
Glucose, glucose-6-phosphate
Which enzyme in glycolysis is responsible for the conversion of glucose to glucose 6-phosphate?
Hexokinase
What reaction does the enzyme hexokinase catalyze?
First step of glycolysis- the phosphorylation of glucose to glucose-6-phosphate.
Why Hexokinase phosphorylated the glucose at first step of glycolysis?
The first step in glycolysis is catalyzed by hexokinase, an enzyme with broad specificity that catalyzes the phosphorylation of six-carbon sugars. Hexokinase phosphorylates glucose using ATP as the source of the phosphate, producing glucose-6-phosphate, a more reactive form of glucose.
How is hexokinase regulated and why is it regulated?
Hexokinase is regulated by feedback inhibition of Glucose-6-Phosphate. Otherwise, you would make more glucose-6-phosphate than the cell can use at one time. you could also reduce phosphate concentrations needed for making ATP, and set up an osmotic gradient which could lead to swelling of the cells
Name one reaction were ATP is required?
The first reaction of glycolysis, where glucose is phosphorylated (a phosphate group is added) to give glucose - 6 - phosphate requires ATP. This reaction is catalyzed by the enzyme hexokinase
What is the substrate of phosphorylase?
The substrate is Glucose-1-phospate which is broken down by only Phosphorylase and produces Starch as its end product
Which has a higher affinity for glucose: hexokinase or glucokinase?
Hexokinase
What is the first stage of glycolisis?
Glucose is converted into Glucose 6 phosphate. One ATP molecule is used.
What is used in glycolysis?
this is shamefully vague question. In glycolysis, glucose and (hexokinase, phosphogluco-mutase, aldolase, triose-phosphate isomerase, glyceraldehyde-phosphate dehydrogenase, phosphoglycerate-kinase, phosphoglycerate mutase, enolase and pyruvate kinase) enzymes are used.
Is glucose a product or substrate?
both
