Feedback inhibition occurs when the end product of a reaction interferes with the enzyme that helped produce it. The inhibitor does this by binding to a second active binding site that's different from the one attached to the initial reactant. The enzyme then changes its shape and can't catalyze the reaction anymore. This type of inhibition is done as a regulatory mechanism to meet the metabolic needs of the cell or organism.
Formaldehyde is a chemical compound that is widely used in industrial manufacturing and a number of other industries. Many people are familiar with it in the form of formalin, an aqueous solution of formaldehyde that is used as an embalming preservative. This chemical is toxic, known to cause cancer and a variety of other health problems, and for this reason, most people make an effort to avoid it.
Formaldehyde is a strong-smelling, invisible chemical used as a binding agent in many areas of manufacturing including wood and fabric materials. Itâs found in furniture, walls, paint, flooring, and more. The formaldehyde gas escapes from these materials and floats around the atmosphere. Sensitivity to the gas can vary from person to person, so an exposure level that goes unnoticed by one person can make another sick or uncomfortable. Asthma sufferers may notice an increase in symptoms when near high levels of formaldehyde, and the gas may be more problematic for young children or the elderly.
