Answer the following questions: Thromboxane is a C20-fatty-acid derivative that contains a cyclic ether ring and oxygen-containing functional groups. It is known to mediate the induction of blood clotting. Based on the classification of biological function, this molecule is a ___. a.membrane lipid b.energy-storage lipid c.messenger lipid d.protective coating lipid e.emulsification lipid The human blood groups, A, B, AB and O, depend on the oligosaccharide part of the glycoprotein on the surface of erythrocyte cells. Which of the following statements differentiates the A and B antigens at their terminal sugar? a. Antigen A has N-acetylgalactosamine terminal sugar while antigen B has galactose. b. Antigen A has N-acetylgalactosamine terminal sugar while antigen B has glucose. c. Antigen A has N-acetylglucosamine terminal sugar while antigen B has glucose. d. Antigen A has N- acetylglucosamine terminal sugar while antigen B has galactose.
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.
