The pH of an enzyme’s surroundings affects the bonds that maintain the enzyme’s structure, which can also affect the enzyme’s activity. Different enzymes have optimal activity at different pH levels, with some enzymes working best in acidic environments and others in neutral or basic environments. video https://cdn.kastatic.org/googleusercontent/cgeKKlbIJ--lGuFsa6QafsoquvCVk3cOAPWW-7-EWOJ-ygeHLcRGu-2lzIoy2xuOzFN3ms5pt1rg9PXv3TxKipA2 Enzyme reaction velocity and pH Enzymes are proteins that catalyze reactions in biological systems.
