In biochemistry, denaturation is a process in which proteins or nucleic acids lose folded structure present in their native state due to various factors, including application of some external stress or compound, such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g., alcohol or chloroform), agitation and radiation, or heat.

In the presence of a non-competitive inhibitor, the apparent enzyme affinity is equivalent to the actual affinity. In terms of Michaelis-Menten kinetics, K m app = K m. This can be seen as a consequence of Le Chatelier's principle because the inhibitor binds to both the enzyme and the enzyme-substrate complex equally so that the equilibrium is ...
Climate change can also be used more broadly to include changes to the climate that have happened throughout Earth's history. [32] Global warming—used as early as 1975 [33] —became the more popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the U.S. Senate. [34] Since the 2000s, climate change has ...
Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH).Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on average.
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
They have been active on topics like acid rain, tobacco smoking, global warming and pesticides. The book says that these scientists have challenged and diluted the scientific consensus in the various fields, as of the dangers of smoking, the effects of acid rain, the existence of the "ozone hole", and the existence of anthropogenic climate ...
[2] [3] Climate change represents long-term changes in temperature and average weather patterns. [4] [5] This leads to a substantial increase in both the frequency and the intensity of extreme weather events. [6] As a region's climate changes, a change in its flora and fauna follows. [7]
Benefits of exoenzyme production can also be lost after secretion because the enzymes are liable to denature, degrade or diffuse away from the producer cell. Enzyme production and secretion is an energy intensive process [ 14 ] and, because it consumes resources otherwise available for reproduction, there is evolutionary pressure to conserve ...
