Isomerase
from class: General Biology I Definition Isomerase is an enzyme that catalyzes the conversion of a molecule into one of its isomers. This process is crucial for various biochemical pathways, including glycolysis.
congrats on reading the definition of isomerase . now let's actually learn it.
Predict what's on your test 5 Must Know Facts For Your Next Test Isomerases play a key role in glycolysis by converting glucose-6-phosphate to fructose-6-phosphate. Phosphoglucose isomerase is a specific type of isomerase involved in the second step of glycolysis. Isomerases facilitate reactions without adding or removing atoms from the substrate, only rearranging them. Mutase, a subtype of isomerase, specifically catalyzes the shifting of functional groups within a molecule. The activity of isomerases ensures the smooth progression and regulation of metabolic pathways such as cellular respiration. Review Questions What role does phosphoglucose isomerase play in glycolysis? How do isomerases differ from enzymes that add or remove atoms from substrates? Why are mutases considered a subtype of isomerases? "Isomerase" also found in:
