The effect of length on flow rate The effect of length on flow rate. A: the fluid reservoir is placed on top of the bench (Figure 2A) to give a pressure head. This is connected to the flow module by rubber tubing with a clamp on it. A 5-mL volumetric flask is used to collect fluid, and the time taken with different lengths of tubes is recorded on a stopwatch. (Figure 2B) The calculated flow rate plotted against the length of tube. Interpret the graph/data Would you expect the length of blood vessels to change in the body as a means of controlling flow? Comment on your answer. Is this likely to be a common mechanism for controlling blood flow to different tissues?
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.
