Purpose: The aim of the study was to assess the influence of substrate concentration on enzyme activity in bio catalysis in Uganda.
Methodology: This study adopted a desk methodology. A desk study research design is commonly known as secondary data collection. This is basically collecting data from existing resources preferably because of its low cost advantage as compared to a field research. Our current study looked into already published studies and reports as the data was easily accessed through online journals and libraries.
Findings: The study revealed crucial insights into enzymatic kinetics and reaction rates. Generally, as substrate concentration increases, the rate of enzymatic activity also increases, following a hyperbolic curve until reaching a plateau, known as the maximum velocity (Vmax). This relationship is described by the Michaelis-Menten equation. At low substrate concentrations, the rate of reaction is directly proportional to substrate concentration, indicating that the enzyme is not saturated and has available active sites for binding. However, as substrate concentration continues to rise, the enzyme becomes saturated, reaching its maximum catalytic capacity, where the rate of reaction remains constant regardless of further increases in substrate concentration. This saturation effect is due to all enzyme active sites being occupied, leading to a plateau in the reaction rate. Additionally, the enzyme's affinity for the substrate, represented by the Michaelis constant (Km), influences the shape of the curve.
Implications to Theory, Practice and Policy: Substrate concentration theory, steady-state theory and allosteric theory may be used to anchor future studies on assessing the influence of substrate concentration on enzyme activity in bio catalysis in Uganda. Provide guidelines for optimizing substrate management strategies in bio catalytic processes to maximize enzyme efficiency and reaction yields. Advocate for policies that support the adoption of optimized substrate management strategies in industrial bio catalytic processes.
