Enzymatic reactions can be inhibited by factors such as temperature, pH, and the presence of inhibitors that bind to the enzyme or substrate. Additionally, substrate concentration can also affect reaction rates; if substrates are in low supply, it may limit the reaction. However, an increase in enzyme concentration typically does not inhibit enzymatic reactions; instead, it usually enhances the reaction rate, assuming sufficient substrate is available.
What else can I help you with?
Do All biochemical pathways have the same number of enzymatic reactions?
No, not all biochemical pathways have the same number of enzymatic reactions. The number of reactions can vary significantly depending on the complexity and purpose of the pathway. For example, simple pathways may involve just a few reactions, while more complex pathways, such as cellular respiration or photosynthesis, can involve many enzymatic steps. Each pathway is uniquely tailored to its specific biological function and the organisms in which it operates.
What type of organic molecule may show enzymatic activity?
Enzymatic activity is primarily associated with proteins, which are organic molecules made up of amino acids. These proteins act as enzymes, catalyzing biochemical reactions by lowering activation energy. Some RNA molecules, known as ribozymes, can also exhibit enzymatic activity by catalyzing specific reactions, demonstrating that not only proteins but also certain nucleic acids can function as enzymes.
When starch was incubated with amylase at 0c did you see any starch digestion?
At 0°C, the activity of amylase is significantly reduced due to the low temperature, which slows down the enzyme's kinetics and may even inhibit its function. Consequently, there would likely be little to no starch digestion observed during the incubation at this temperature. Enzymatic reactions generally require optimal temperatures to proceed effectively, and 0°C is below the typical range for amylase activity.
What is residual substrate?
Residual substrate refers to any material leftover or remaining after a chemical reaction or process has taken place. In the context of biotechnology or enzymatic reactions, residual substrate may refer to the unutilized or partially degraded substrate that remains in the system after the reaction is complete. Understanding and managing residual substrates is important in optimizing reactions and maximizing product yields.
How could you slow down the enzyme?
This would depend on what kind of reaction you are referring to. Endothermic (heat-absorbing) reactions would slow down at lower temperatures. Exothermic (heat-releasing) reactions would gain speed at lower temperatures. Inhibitors to the reaction can slow down biological processes.

What does a lower substrate concentration signify in enzymatic reactions?
A lower substrate concentration in enzymatic reactions indicates that there is less of the molecule that the enzyme acts upon. This can affect the rate of the reaction, as enzymes require substrates to bind to and convert into products. With lower substrate concentrations, the reaction may proceed more slowly until more substrates are available for the enzyme to work on.
What are the by product of enzymes?
The byproducts of enzymes are the substances produced as a result of enzymatic reactions. Enzymes catalyze biochemical reactions, converting substrates into products, and any remaining unreacted substrates or intermediate compounds can be considered byproducts. Additionally, some enzymatic reactions may release energy or produce molecules like water, carbon dioxide, or other small metabolites as byproducts. The specific byproducts depend on the enzyme's function and the substrates involved in the reaction.

Why use chloroform in DNA extraction for plant?
Chloroform is used in DNA extraction from plants primarily to facilitate the separation of DNA from proteins and other cellular debris. It helps to create a biphasic solution where DNA remains in the aqueous phase while proteins and lipids partition into the organic phase. This enhances the purity of the extracted DNA, making it suitable for downstream applications such as PCR and sequencing. Additionally, chloroform can help to remove phenolic compounds that may inhibit enzymatic reactions.
When can refrigeration not applicable to preserve sample for enzymatic assay?
Refrigeration is not applicable to preserve sample for enzymatic assay because enzymes may lose their activity at extremely low temperatures as well. This may account for storing enzymes at 5° C or below without affecting the enzymatic activity permanently. (Anubhav, 2012)
Does gelatin inhibit PCR?
Yes, gelatin can inhibit PCR (Polymerase Chain Reaction) by affecting the activity of DNA polymerase and interfering with the binding of primers to the template DNA. It may introduce contaminants or alter the ionic environment, which can lead to suboptimal amplification. Therefore, it is generally advisable to minimize or avoid gelatin in PCR reactions to ensure successful amplification of DNA.
What is residual substrate?
Residual substrate refers to any material leftover or remaining after a chemical reaction or process has taken place. In the context of biotechnology or enzymatic reactions, residual substrate may refer to the unutilized or partially degraded substrate that remains in the system after the reaction is complete. Understanding and managing residual substrates is important in optimizing reactions and maximizing product yields.
What is the range of factors that may enhance or inhibit human development?
Factors that may enhance human development include a positive environment, healthy food, and education. Factors that may inhibit include genetics, illness, culture, and disability.
What are not short term stress reactions?
Chronic stress reactions are not short term and can persist for an extended period. These reactions can include ongoing fatigue, irritability, trouble sleeping, and changes in appetite. Seeking professional help may be beneficial if experiencing chronic stress reactions.
How does manganese interact with other nutrients?
High doses of manganese may inhibit the absorption of iron, copper, and zinc. Alternatively, high intakes of magnesium, calcium, phosphorus, iron, copper, and zinc may inhibit the absorption of manganese.
