National 5 Proteins Effect of pH on enzyme activity Proteins consist of combinations of amino acids. Body proteins include structural proteins, enzymes, hormones and antibodies.

A demonstration of the key points of the required practical to investigate the effect of pH on enzyme activity for GCSE biology and combined science.

Summary The factors that affect enzyme catalysis (that is, enzyme activity) will definitely affect the rate of enzymatic reactions, but the factors that affect the rate of enzymatic reactions do not ...

Method Summary This article describes a simple method to determine the optimum pH for the activity of one enzyme in a coupled enzyme assay. Decoupling of the two-step reaction is achieved by heat ...

Soil pH and available N were also measured. Results We found that soil N availability primarily controlled plant community composition, but pH controlled the composition of the microbial community, ...

Furthermore, many researchers have attempted to improve enzyme stability and to enhance enzyme activity by rational design and in vitro evolution of enzymes. 19, 20, 21, 22, 23 In most cases ...
