Many organisms can decompose hydrogen peroxide (H2O2) enzymatically. Enzymes are globular proteins, responsible for most of the chemical activities of living organisms. They act as catalysts, substances that speed up chemical reactions without being destroyed or altered during the process. Enzymes are extremely efficient and may be used over and over again. One enzyme may catalyze thousands of ...
Enzymes are biological catalysts capable of speeding up chemical reactions by lowering activation energy. One benefit of enzyme catalysts is that the cell can carry out complex chemical activities at a relatively low temperature. Most enzymes are proteins and their 3-dimensional shape is important to their catalytic activity.

18. Do enzymes act better under acidic or alkaline pHs? Most enzymes act under pHs between 6 and 8, a range that corresponds to the general acidic level of cells and blood. There are enzymes, however, that act only under very acid or very alkaline pH. Therefore, enzyme activity depends on pH range. An arsenal of laboratory methods is available to screen blood, diagnose infection, and monitor disease progression in individuals infected by HIV. These tests can be classified into those that: 1) detect antibody, 2) identify antigen, 3) detect or monitor viral nucleic acids, and 4) provide an estimate of T-lymphocyte numbers (cell phenotyping).
