Best Answer: One acre is slightly less than 91 yards on an American Football field, with the full field, including the end zones, covering approximately 1.32 acres. So 10 acres is about 7.5 football fields.
Alkaline phosphatase is an ectoenzyme that acts on micromolar concentrations of natural substrates at physiologic pH in human osteosarcoma (SAOS-2) cells. Arch Biochem Biophys 1988; 264: 400â9.
This action is directly opposite to that of phosphorylases and kinases, which attach phosphate groups to their substrates by using energetic molecules like ATP. A common phosphatase in many organisms is alkaline phosphatase.
