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.
Enzymes /ËÉnzaÉªmz/ are macromolecular biological catalysts. Enzymes accelerate, or catalyze, chemical reactions. The molecules at the beginning of the process are called substrates and the enzyme converts these into different molecules, called products.ome household products use enzymes to speed up chemical reactions: enzymes in biological washing powders break down protein, starch or fat stains on clothes, and enzymes in meat tenderizer break down proteins into smaller molecules, making the meat easier to chew.
