Describe the specific multi-enzyme example discussed in class of how enzyme activity can be altered by changing its substrate to product ratio.
Enzyme kinetics
In biochemistry, enzymes are proteins that act as biological catalysts. Catalysis is the addition of a catalyst to a chemical reaction to speed up the pace of the reaction. Catalysis can be categorized as either homogeneous or heterogeneous, depending on whether the catalysts are distributed in the same phase as that of the reactants. Enzymes are an essential part of the cell because, without them, many organic processes would slow down and thus will affect the processes that are important for cell survival and sustenance.
Regulation of Enzymes
A substance that acts as a catalyst to regulate the reaction rate in the living organism's metabolic pathways without itself getting altered is an enzyme. Most of the biological reactions and metabolic pathways in the living systems are carried out by enzymes. They are specific for their works and work in particular conditions. It maintains the best possible rate of reaction in the most stable state. The enzymes have distinct properties as they can proceed with the reaction in any direction, their particular binding sites, pH specificity, temperature specificity required in very few amounts.
Describe the specific multi-enzyme example discussed in class of how enzyme activity can be altered by changing its substrate to product ratio.
Enzymes are usually comprised of proteins. It work as a catalyst for several biochemical reactions. Enzymes works by decreasing the activation energy of the reaction without being consumed.
Multienzyme complex are enzymes which carries out a single or a series of biochemical reactions inside the cells. Purpose of multienzyme complex is to segregate certain biochemical pathways into one part of the cell. e.g. pyruvate dehydrogenase, fatty acid synthetase, glutamine synthetase, proteasome, rubisco, etc.
The enzyme activity indicates the rate of reaction which indicates how much substrates converted into product per unit time or how much product is formed from the substrate in per unit time. Enzyme activity is affected by several factors like temperature, pH, concentration of enzyme and substrate, and the presence of inhibitors or activators.
