Can enzymes be deactivated?
Enzymes can be denatured, which means if the surrounding temperature of the enzyme passes the specific enzymes optimum temperature, the activesite of it changes and it doesn't work any more. This is a denatured enzyme. This i suppose is a type of deactivation?
When we refer to the phosphate - PO4= - ion, the addition / phosphorylation and removal / de-phosphorylation of this phosphate group / moiety (thereby altering the enzyme's shape) is the way that some types of enzymes are turned on or off / activated or deactivated. The Kinase group of enzymes - that control the Cell cycle - is an example.
Hyperthermia is an abnormal increase in the core body temperature. Extreme hyperthermia (usually defined as greater than 106 degrees F in humans) caused the enzymes within the body's cells to degrade and inactivate. If enough enzymes are deactivated, the cell dies. If enough cells die, or enough of a particular cell such as a cranial neuron die, the organism will also die.
If you requested that your account be deactivated: Type your password and email address into their respective boxes as if logging in, and your account should reactivate. If Facebook deactivated your account for a violation: It cannot be done. Or will not be done. Either way the end result is the same.
The following are some of the things that might happen when food is cooked: # Enzymes are deactivated # Pathogenic Microorganisms and Parasites are killed or greatly reduced # Protein structure is denatured # The cell structure is broken down, possibly tenderizing the food and making it easier to eat and digest
In the U.S. they have to be deactivated to be sold. Around $10-$15 if deactivated. If it hasn't been deactivated best thing to do is drop it off at the local cop shop for disposal. Most police stations have an annual program that you can drop the stuff off without any questions. Had a friend that did bomb & E.O.D. for 20 years for the local police station.
