Unformatted text preview: ENZYMES A cells metabolic pathways (which chemical reactions occur in that cell) are determined by which enzymes the cell makes, which is determined by the genes present. Chemical reactions occur as ions, atoms, or molecules collide. Conditions in living cells involve temperatures and pressures that are mostly too low for enough of these collisions to occur with enough force to result in reactions at a rate that will maintain life. To increase the speed of reactions in cells, biological catalysts called enzymes are essential. (Catalyst- substance that can speed a chemical reaction without itself being altered). Enzymes work in 2 major ways: 1. In catabolic reactions, enzymes hold the larger molecule in such a way that chemical bonds are strained and more easily broken....
