I have a fill in the blank question. "1) Heterophobic or Homotrophic effects= are changes in affinity due to substrate binding and cooperativity between different subunits. They give Allosteric rate curves their Sigmoid shape. 2) Hetero or Homotrophic effects=are changes in affinity due to binding of an effector to an Allosteric site.  Allosteric sites are usually 3)located outside or inside the active site.  Positive Allosteric effectors (activators) shift the rate curve 4) Left or Right, where Negative effectors shift it 5) right or left.  Positive Allosteric effectors usually stabalize the 6)T or R state.  Negative efftors usually satbalize the R state."

Metabolic pathways

Metabolism is defined as the group of life-supporting, enzyme-mediated chemical reactions in organisms. A metabolic pathway is a set of these chemical reactions that involve anabolism (synthesis of complex biomolecules) and catabolism (breakdown of biomolecules into small molecules) that occur inside a cell. Metabolites are the reacting substances, products, and intermediate substances of an enzymatic process that are altered by a series of chemical events catalyzed by enzymes.
