What does cooling and heating do to enzyme activity?
Cooling generally slows down enzyme activity by decreasing the kinetic energy of the enzyme molecules, limiting their ability to collide with substrate molecules and facilitating the formation of enzyme-substrate complexes. Heating, on the other hand, initially increases enzyme activity by providing more kinetic energy for enzyme-substrate collisions and enhancing the rate of reaction. However, excessive heat can denature enzymes, causing them to lose their shape and function, ultimately decreasing enzyme activity.
Will enzyme activity increase with an increase in temperature?
Warmer temperatures mean little more than that molecules are moving more rapidly. This promotes enzyme activity on its own, however, as movement allows the enzymes to react to more material in a shorter amount of time.
How would one overcome the effects of a competitive inhibitor on enzyme activity in the biochemical regulation of metabolic pathways?
Increase the amount of substrate for the enzyme.
What switchs on enzyme activity while what can switch off or reduce enzyme activity?
activators; inhibitors
What can change the way an enzyme acts?
Enzyme activity is affected by other molecules, temperature, chemical environment (e.g., pH), and the concentration of substrate and enzyme. Activators are molecules that encourage enzyme activity, and inhibitors are enzymes that decrease enzyme activity. Sometimes a cofactor is necessary for the enzyme to work.
What can high blood pressure do to enzyme activity?

How is nevirapine used to treat HIV infections?
It alters the active site of reverse transcriptase, decreasing that enzyme's activity.
Will enzyme activity be higher or lower if the pH is high?
Yes it does. Enzymes increase rate of reaction as the pH level increases but enzymes work best at optimum pH. If pH level still increase, then enzyme will become denatured and rate of reaction once again decreases.
What is the Effect of dilution on enzyme activity?
At a high ion concentration, the ion interfere with the bonds between the side groups of the amino acids making up the enzyme (which is a protein). This causes the enzyme to lose its shape, called denaturation. If the enzyme loses its shape, it can no longer accept and react substrate, so the rate of enzyme activity decreases.
Will enzyme activity increase with an increase in temperature?
Warmer temperatures mean little more than that molecules are moving more rapidly. This promotes enzyme activity on its own, however, as movement allows the enzymes to react to more material in a shorter amount of time.
Why does increase enzymes concentration promote enzyme activity?
Increasing enzyme concentration increases the number of collisions between the enzyme molecules and the substrate molecules. This increases the number of successful collisions and the number of enzyme-substrate complexes. Therefore the reaction rate is increased as well and enzyme activity is promoted.
How would one overcome the effects of a competitive inhibitor on enzyme activity in the biochemical regulation of metabolic pathways?
Increase the amount of substrate for the enzyme.
What can you do to regain the activity of the enzyme?
The enzyme is inactive at this point. New enzyme must be added to regain enzyme activity
3 factors that influence enzyme activity?
The three main factors that affect enjyme activity are:- a)Temperature:Enzymes generally function properly at a narrow rangr of temperature and shows its highest activity t a particular temperature called its optimum temperature. b)pH:-as temperature pH also has a particular value ,in which the enzymes are most active,called the optimum temperature. c)Concentration of substrate;-with the increase in substrate concentration,the velocity of the enzymatic reaction also increases,till a maximum velocitywhich does not rise any further with the rise in substrate concentration.
What is the effect of hydrochloric acid on the enzyme activity?
Denature enzyme activity
What are some factors that may influence enzyme activity?
Factors affecting enzyme activity1: Enzyme concentrationIf the quantity of enzyme is doubled, the enzymatic activity will also be doubled because more enzymes are now available to work. After a certain level of enzyme concentration, there will be no more increase in the enzymatic activity because all the substrate molecules are combined with an enzyme and the rate of reaction will stabilize.2: Substrate concentrationBy increasing substrate concentration, enzymatic activity increases. Increasing the substrate further without increasing the enzyme concentration will not affect the enzymatic activity because all the enzymes are occupied by a substrate molecule.3: pH valueSome enzymes require acidic surroundings, most require a more neutral condition for their activity. Change in the pH can change the enzyme's structure and enzyme become useless.4: TemperatureAn increase in temperature of 10 degree celsius doubles the enzymatic activity. Each enzyme has its own optimum temperature at which its enzymatic activity is maximum. Very high temperatures break the bonds that maintain shape of enzyme. If the enzyme denatures, the substrate can not fit in to the active sites and enzyme become useless.
