: Maximum velocity when the enzyme is completely saturated with substrate. : Substrate concentration. Kmcap K sub m

Most human enzymes work best at 37°C. High heat breaks the bonds holding the protein together. pH Levels: : Maximum velocity when the enzyme is completely

Enzymes can be reversibly activated or deactivated by the attachment of chemical groups. The most common form is , where a phosphate group is added to a specific amino acid (like serine or threonine) by an enzyme called a kinase, and removed by a phosphatase. 3. Zymogens (Proenzymes) High heat breaks the bonds holding the protein together

In a laboratory setting, chemical reactions often require extreme temperatures, harsh pH levels, or organic solvents to proceed at a measurable rate. In contrast, enzymes achieve far greater catalytic efficiency under mild physiological conditions: a neutral pH, aqueous environments, and a ambient body temperature (typically 37°C in humans). chemical reactions often require extreme temperatures
