deaktivaci

Deaktivace is the Czech term for deactivation, the process of rendering something inactive or nonfunctional. It can be temporary or permanent, reversible or irreversible, and it appears in many contexts with domain-specific meanings.

In information technology and online services, deaktivace refers to disabling a user account, feature, or device. It may be voluntary or required for security, regulatory compliance, or inactivity. Data associated with deactivated entities is often archived or deleted according to privacy rules, and reactivation may require authentication.

In chemistry and biochemistry, deaktivace describes loss of activity in a catalyst or enzyme. Causes include denaturation, fouling, poisoning, or inhibitor binding. Catalyst or enzyme activity can sometimes be restored by regeneration or renaturation, but other forms of deactivation are permanent.

In pharmacology and physiology, deactivation (or deaktivace) denotes the process by which a drug or signaling pathway loses activity. Drugs are often metabolically deactivated by the liver, reducing potency and enabling elimination. Regulatory mechanisms may deactivate receptors or signaling steps to maintain homeostasis.

In industrial and infrastructure contexts, deaktivace can denote safe shutdown, decommissioning, or retirement of equipment, sensors, or systems after use. This includes procedures for data handling, safety assessment, and compliance with environmental or data-protection rules.
