What role do metabolic inhibitors play in the study of glycolysis?
They block the glycolytic pathway at specific points.
How does iodoacetate affect yeast extracts in relation to fructose-1,6-bisphosphate?
It causes the accumulation of fructose-1,6-bisphosphate.
What is the consequence of fluoride exposure on yeast extracts in relation to phosphate esters?
Causes the buildup of various phosphate esters.
Why was it crucial to isolate and characterize glycolytic intermediates in the study of the pathway?
To aid in deducing the steps of the glycolytic pathway.
How did chemical intuition contribute to predicting the steps in the glycolytic pathway?
By leveraging information on accumulated intermediates.
Test your knowledge on cell organelles and their functions, as well as key metabolic pathways such as citric acid cycle, glycolysis, and fatty acid oxidation. Learn about the roles of mitochondrion, cytosol, lysosomes, nucleus, and Golgi apparatus in cellular processes.
