Enzymes are biological catalysts which cause the rate of a reaction to increase (by providing an alternate reaction pathway with a lower activation enthalpy). They are very specific to the reaction they catalyse.
Denaturation: changes in pH or temperature can alter the enzyme's structure, rendering it inactive. Inhibition: the presence of inhibitors that bind to the enzyme active site or allosteric site can prevent enzyme-substrate binding. Mutations: changes in the enzyme's genetic sequence can disrupt its function by affecting its ability to bind substrate or catalyze reactions.
One common test to detect the presence of an enzyme in a biological washing powder is to perform an enzyme activity test. This can be done by measuring the rate of reaction or the products formed when the enzyme acts on its substrate. Another method is to use specific substrates that change color when acted upon by the enzyme, indicating its presence.
The secondary antibody in an ELISA test is conjugated with an enzyme to amplify the signal produced when the antibody binds to the target antigen. This enzyme-substrate reaction generates a detectable signal that indicates the presence of the antigen, which allows for more sensitive and accurate detection in the ELISA assay.
An enzyme is called a denatured enzyme once it changes its shape.
Extreme temperatures and pH levels outside of the enzyme's optimal range are two factors that could cause enzyme denaturation. Additionally, exposure to certain chemicals or heavy metals can also lead to enzyme denaturation.

When a protein is denatured, this can cause an enzyme to lose its confirmation.
Yes, inhibitors can decrease enzyme activity by binding to the enzyme and preventing substrate binding. Activators can increase enzyme activity by binding to the enzyme and enhancing substrate binding or catalytic activity. Both inhibitors and activators can modulate enzyme activity by changing the enzyme's structure or function.

When activation energy is in the presence of an enzyme, the enzyme can lower the activation energy barrier required for a chemical reaction to occur. This allows the reaction to proceed at a faster rate and with lower energy input. The enzyme does this by stabilizing the transition state of the reaction, making it easier for the substrate molecules to react.
Factors that could impact the function of an enzyme include temperature, pH levels, substrate concentration, enzyme concentration, presence of inhibitors or activators, and cofactors or coenzymes. These factors can alter the enzyme's structure, affecting its ability to bind to substrates and catalyze reactions efficiently.
ONPG test detects only presence of beta galactosidase enzyme whereas lactose fermentation requires the presence of permease as well as beta galactosidase enzyme.

Physical activity can alter the shape of enzyme which can cause damage or may the enzyme become inactive
The presence of the flesh-eating enzyme in pineapples, called bromelain, can aid in the digestion of proteins in the human digestive system. Bromelain helps break down proteins into smaller molecules, making it easier for the body to absorb nutrients. However, consuming large amounts of bromelain may cause irritation or sensitivity in some individuals.
