When an organic product such as pyruvic acid is the final electron acceptor in the metabolic pathway the pathway is termed?
fermentation

An excess of end-product molecules alters the shape of the first enzyme in the pathway and shuts off that metabolic pathway?
Feedback Inhibition
What fuel are used in the anaerobic metabolic pathway?
The anaerobic glycolysis energy pathway produces ATP from carbohydrates only. This energy pathway produces lactic acid as a by product.
What is the wast of product of respiration?
Cellular respiration produces CO2 and water as by-products of the metabolic pathway.
What end product from a metabolic pathway binds to an enzyme involved in a reaction at the beginning of the pathway. changing the shape of the active site and preventing the enzyme from?
Feedback inhibition
What happens in a metabolic pathway?
The product inhibits the activity of the first enzyme
Why is it important that metabolic pathways are regulated?
They can work via allosteric inhibition, where the final product in large amounts binds to a site (not the active site, but an allosteric site) which stops the enzymes involved in the early phases of the metabolic pathway. In other words, the final product can act as an inhibitor to stop the enzyme early in the metabolic pathway by deactivating it.
What is the catalyst in a metabolic pathway?
Enzymes are catalysts in metabolic pathways.
What is the meaning of metabolic pathway?
A sequence of chemical reactions that lead from some precursor to a product, where the product of each step in the series is the starting material for the next step.
The Krebs cycle is an example of which type of metabolic pathway?
Cyclic pathway
What is an example of an Amphibolic pathway?
A metabolic pathway that involvs both anabolism and catabolism.
