The two factors of primary importance affecting water density are temperature and salinity. These are an important influence on global ocean currents. The process of conve â¦ rgence and divergence also plays an important role on controlling the water density of Oceans. In addition, the density of water increases slightly with increasing pressure and this can become a factor at the tremendous pressure of the deep ocean.
Examples of these biosynthetic pathways include the production of lipid membrane components and nucleotides. The prerequisite elements for biosynthesis include: precursor compounds, chemical energy (e.g. ATP), and catalytic enzymes which may require coenzymes (e.g. NADH, NADPH). These elements create monomers, the building blocks for macromolecules.
The role of the enzyme is to reduce the activation energy, by bringing specific molecules together, rather than relying on random collisions) Action on specific Substrates. Enzymes are substrate specific, meaning only one particular substrate molecule can work with one particular enzyme. This is due to the reciprocally shaped active site. Since the enzyme is never chemically alter by a reaction, it can be reused in subsequent reactions â enzyme controlled reactions are always reversible.
