1 Ιουλ 2023 · Both temperature and pH affect enzymes, but temperature has far stronger interactive effects with process duration, which has scarcely been considered. To fill this technology gap, we investigated both short- and long-term temperature effects on Aspergillus niger carbohydrases.

The results show directly how the Equilibrium Model parameters are affected by the data. The methods described in the present paper allow the determination of the new parameters Δ Heq and Teq, required for any description of the way in which temperature affects enzyme activity.
26 Ιουλ 2022 · The temperature: Each enzyme has an optimum temperature at which it works best. A higher temperature generally results in an increase in enzyme activity. As the temperature increases, molecular motion increases resulting in more molecular collisions.
2 Σεπ 2013 · A large ΔH eq leads to an enzyme with a sharp and relatively narrow temperature optimum, whereas a small ΔH eq results in an enzyme with a broad temperature optimum, so that activity is relatively less sensitive to changes in temperature (Fig. 3).
31 Μαρ 2024 · As temperature increases and approaches the optimal temperature for an enzyme, activity increases. As temperature increases above the optimal temperature, however, enzyme activity decreases and eventually the enzyme can lose its structure (i.e., denature) and ability to function.
13 Σεπ 2007 · Introduction. If an enzyme is assayed for a fixed duration over a range of temperatures, we observe a plot with an apparent optimum (Fig. 1). This observed “optimum temperature” is not an intrinsic enzyme property, since it arises from a mixture of thermal properties, and from assay duration.
16 Φεβ 2016 · The increase in enzymic rates with temp. up to an optimum temp. (Topt) is widely attributed to classical Arrhenius behavior, with the decrease in enzymic rates above Topt ascribed to protein denaturation and/or aggregation.
