Enzymes in the stomach, such as pepsin ( which digests protein ), work best in very acid conditions ( pH 1 - 2 ), but most enzymes in the body work best close to pH 7. In a most efficient and elegant way, cells have evolved to use the products of their own reactions for feedback inhibition of enzyme activity.Feedback inhibition involves the use of a reaction product to regulate its own further production .

Every biologist is familiar with the profile of the rate of an enzymatic reaction versus temperature as shown in the figure. of alkaline enzyme is protease. What if you have a pH higher than 7 - in other words under alkaline conditions. What is Enzyme Activity? Under the influence of very high temperature, the enzyme molecule tends to get distorted, due to which the rate of reaction decreases. Some enzymes work most efficiently in acidic solutions whereas others work best in basic solutions. Read and learn for free about the following article: Enzymes review If you're seeing this message, it means we're having trouble loading external resources on our website. The digestion lab experiment was conducted for the purpose of understanding digestive enzymes and how they work, and under which conditions they function best. The most efficient enzymes in your body can perform a million reactions per second, and do so under chemically mild conditions. Enzymes work most efficiently under optimal conditions that are specific to the enzyme. In the human body, the optimum temperature at which most enzymes become highly active lies in the range of 95 °F to 104 °F (35 °C to 40 °C). At lower temperatures, they will still work but much more slowly. Although new enzymatic detergent formulations are very effective, enzymes work best under certain environmental conditions such as specific temperature ranges, pH levels, and washer settings and in combination with other chemical ingredients. Hydrogen peroxide is the byproduct of numerous biological processes, and to break down this molecule, the body uses an enzyme called catalase. The only thing maltase can do is break maltose molecules, but it can do that very rapidly and efficiently. D. Enzymes are highly specific and act on chemicals called substrates. At lower temperatures, they will still work … Without enzymes, reactions would be significantly slower and we would not be able to do the most basic functions, such as breathing or digesting food. If you're behind a web filter, please make sure that the domains *.kastatic.org and *.kasandbox.org are unblocked. Enzymes can only work in certain conditions. . At the correct pH, the charges around the active site are complementary to those of the substrate allowing them to slot together. Because ionic and hydrogen bonds are important factors in enzymes retaining their specific shapes, pH levels that interrupt this bonding, negatively impact enzyme activity. Condition like pH and temperature can affect the protein and cause an alteration to its structure. This is the optimum temperature for this enzyme. E. Most enzymes work best under high salt conditions. Source(s): My …

. For e.g. Like most enzymes, the activity of catalase is highly dependent on temperature. 10. Protein - Protein - Inhibition of enzymes: Some molecules very similar to the substrate for an enzyme may be bound to the active site but be unable to react. Enzymes work best when there is a high enough substrate concentration for the reaction they catalyse. An enzyme is protein and it needs to maintain its 3D structure as the enzyme work like "lock and key". With time, research, and improved protein engineering methods, many enzymes have been genetically modified. An allosteric site is an alternate part of the enzyme that can bind to non–substrate molecules. Most enzymes in the human body work best at around 37°C – body temperature. A graph of enzyme activity plotted against temperature is shown below.

If this occurs, then tissues can be damaged if the enzyme affected can't break down the substrate fast enough. So they work efficiently If an enzyme is not in its optimal conditions, it doesn't work as well. Most enzymes in the human body work best at around 37°C – body temperature. This enzyme is typically used in the textile industry for fabric treatments. In other words, a denatured enzyme fails to carry out its normal functions. The substrates bind to a region on the enzyme called the active site. For example, most enzymes will not work under very acidic conditions but for the enzymes in our stomach, the optimum pH is as low as 1.5 (acidic). For example, without the presence of an appropriate enzyme, the glucose molecules and phosphate molecules in glucose-6-phosphate will remain bonded. Amylase is an type of enzyme. However, this does not mean the enzyme(s) being used were as efficient as they could be. Enzyme activity is a measure of how well (how efficiently) an enzyme works as a catalyst. But if the pH/temperature …

Various enzymes function most efficiently under different sets of “optimal” conditions.

Such molecules cover the active site and thus prevent the binding of the actual substrate to the site. For instance, animals from the Arctic have enzymes adapted to have lower optimum temperatures while animals in desert climates have enzymes adapted to higher temperatures. The molecules that an enzyme works with are called substrates.
