What else can I help you with?
What effect does iodoacetate have on glycolysis?
iodoacetate inhibits the enzyme glyceraldehyde 3-phosphate dehydrogenase which is a enzyme in glycolysis
Is magnesium a cofactor of glycolysis?
Magnesium is not a direct cofactor of glycolysis, but it is required for the activity of some enzymes involved in glycolysis. For example, magnesium is needed for the activation of the enzyme phosphofructokinase, which is a key regulatory enzyme in glycolysis. Magnesium helps stabilize the ATP molecule during the phosphorylation reactions in glycolysis.
How many of the glycolysis enzyme molecules does a cell have?
It has 2 ATP molecules.
Which enzyme catalyzes the rate-limiting step of glycolysis?
Phosphofructokinase (PFK)
What is an acetokinase?
An acetokinase is an enzyme which catalyzes the phosphorylation of acetate as part of the process of glycolysis.
Which enzyme in glycolysis is responsible for the conversion of glucose to glucose 6-phosphate?
Hexokinase
What cell would the enzyme GALT be found?
Since it is linked to the pathway of glycolysis which takes place in the cytosol, the enzyme GALT would be present in the cytosol. This is where glycolysis occurs.
The enzyme phosphofructokinase is an important enzyme that plays a significant regulatory role in glycolysis. Which of the following conditions would be expected to result in increased activity of this enzyme?
Low levels of ATP
What is the name of the enzyme used to produce ATP inoxidation phosphorylation?
Phosphoglycerate kinase in glycolysis
The enzyme enolase catalyzes the ninth reaction of glycolysis. What is the product of this reaction?
Phosphoenolpyruvate (PEP)
What is the control point in glycolysis?
The control point in glycolysis is the enzyme phosphofructokinase. This enzyme catalyzes the conversion of fructose 6-phosphate to fructose 1,6-bisphosphate, a key step in the glycolysis pathway. Phosphofructokinase activity is allosterically regulated by ATP, citrate, and AMP levels in the cell.
Which kind of metabolic poison would most directly interfere with glycolysis?
The type of metabolic poison that would most directly interfere with glycolysis would be an agent that isn't metabolized, yet closely mimics the structure of glucose. Glycolysis acts as a metabolic pathway.
