Countercurrent flow of blood and water is more efficient than concurrent flow because a … is maintained which drives oxygen from water to blood
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.
Countercurrent flow is the flow of anything in opposite direction and concurrent flow is the flow of anything in same direction.
Countercurrent exchange is more efficient than concurrent exchange mechanism. Before described the question I want to explain one simple idea of that through an example. In a classroom if there is one gate for the entry and exit of the students and in another classroom there is two get, one is specified for entrance and other one for exit. So it clearly depict that two ways system is much better than a single way system. In single get we will be found more congestion. Same idea applied on countercurrent exchange and concurrent exchange mechanism.
