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.
Oxygen is produced as a by-product of photosynthesis. ] and making new proteins. For this reason enzymes are sometimes called biological catalysts. Enzymes speed up (catalyse) chemical reactions occurring inside and outside of living cells. This includes: 1  DNA replication. 2  Protein synthesis. 3  Digestion.
