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 are large molecules that speed up the chemical reactions inside cells. Each type of enzyme does on specific job. Enzymes are a type of protein, and like all proteins, they are made from long chains of different amino acids. Biological catalysts Enzymes are soluble protein molecules that can speed up chemical reactions in cells. These reactions include respiration, 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.
