WebAn important element in human chemistry, an enzyme is a protein manufactured by a … Webcofactor, a component, other than the protein portion, of many enzymes. If the cofactor is removed from a complete enzyme (holoenzyme), the protein component (apoenzyme) no longer has catalytic activity. A cofactor that is firmly bound to the apoenzyme and cannot be removed without denaturing the latter is termed a prosthetic group; most such groups …

WebJul 4, 2024 · Enzymes. Enzymes are catalysts that drive reaction rates forward. Most catalysts, but not all, are made up of amino acid chains called proteins that accelerate the rate of reactions in chemical systems. The functionality of a catalyst depends on how the proteins are folded, what they bind to, and what they react with.

WebTranscription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template). Transcription has three stages: initiation, elongation, and termination. WebEnzyme activity is measured in units which indicate the rate of reaction catalysed by that enzyme expressed as micromoles of substrate transformed (or product formed) per minute. An enzyme unit is the amount of enzyme that will catalyse the transformation of 1 μmol of substrate/min under specified conditions of pH and temperature. The specific ...
