What are the irreversible reactions of glycolysis and how do they occur under intracellular conditions?
The irreversible reactions of glycolysis are catalyzed by enzymes that only work in one direction. These reactions occur under intracellular conditions when the concentration of reactants and products favors the forward direction of the reaction, making it energetically favorable. This ensures that the glycolytic pathway proceeds efficiently towards the production of energy in the form of ATP.

Which irreversible reactions are involved in glycolysis?
The irreversible reactions in glycolysis are catalyzed by the enzymes hexokinase, phosphofructokinase, and pyruvate kinase. These reactions involve the conversion of glucose to glucose-6-phosphate, fructose-6-phosphate to fructose-1,6-bisphosphate, and phosphoenolpyruvate to pyruvate, respectively.
What are the irreversible reactions of glycolysis and how do they contribute to the overall regulation of the pathway?
The irreversible reactions of glycolysis are catalyzed by enzymes hexokinase, phosphofructokinase, and pyruvate kinase. These reactions help regulate the flow of glucose through the pathway by committing glucose to be broken down into pyruvate. This regulation ensures that glycolysis proceeds efficiently and that the cell can generate energy effectively.
What is the purpose of the fermentation reactions after glycolysis?
The purpose of fermentation reactions after glycolysis is to regenerate NAD+ so that glycolysis can continue producing ATP in the absence of oxygen. Fermentation allows for the conversion of pyruvate into different end products (such as lactate or ethanol) to maintain cellular energy production in anaerobic conditions.
Where in a eukaryotic cell do the reactions of glycolysis occur?
The reactions of glycolysis occur in the cytoplasm of a eukaryotic cell. The enzymes required for glycolysis are found in the cytoplasm, where glucose is broken down into pyruvate to produce energy in the form of ATP.
Whereabouts in the cell are the enzymes found that catalyze the reactions of glycolysis?
The enzymes that catalyze the reactions of glycolysis are found in the cytoplasm of the cell. This is where glycolysis takes place, as it is the first step in cellular respiration and does not require a membrane-bound organelle like the mitochondria.

What enzymes in the glycolysis pathway in the liver catalyze irreversible reactions?
Glucokinase, phosphofructokinase-1, pyruvate kinase
What reversible and irreversible reactions can you find at home?
Cooking involve irreversible chemical reactions.
Which are more in nature reversible or irreversible chemical reactions?
irreversible
Does the recycling of ATP ensure the continuation of glycolysis under anaerobic conditions?
Yes, the recycling of ATP ensures the continuation of glycolysis under anaerobic conditions by providing the necessary energy for the reactions to proceed. This is particularly important in anaerobic conditions where the final products of glycolysis cannot be further metabolized through aerobic respiration for additional ATP production.

Is all physical reactions are reversible?
No, not all physical reactions are reversible. Some physical reactions are irreversible, meaning they cannot easily be undone or reversed to their original state. Examples of irreversible physical reactions include burning a match or breaking a glass.
Is there a science to cooking?
Yes, all cooking is irreversible reactions.
What are the two terms that are anaerobic chemical reactions?
Fermentation and glycolysis are two examples of anaerobic chemical reactions where energy is produced without the presence of oxygen.
In glycolysis many reactions occur what is the main outcome of these reactions?
Glucose is broken down into pyruvate.
