The chemical requirements for microbial growth include carbon, nitrogen, phosphorus, and sulfur. Why do all cells need nitrogen?
View Available Hint(s) The chemical requirements for microbial growth include carbon, nitrogen, phosphorus, and sulfur. Why do all cells need nitrogen? as an energy source as part of the phospholipid bilayers that form the cell membranes for maintaining a favorable pH for building amino acids, proteins, and nucleic acids
Answer: For building amino acids, proteins and nucleic acids.
Explanation:
Living cells requires nitrogen because they are major part of amino acids. They form the building block of protein and nucleic acids such as DNA which carry the genetic information and is passed from generations to generations. Plants and animal need nitrogen for growth and survival. The protein is use for building and repairing muscles and it is a necessity for growth.
Exocytosis moves materials out of a cell. Endocytosis moves materials into a cell. Active transport uses carrier proteins. (not entirely sure about this one... check it out to be sure) Molecules move from an area of high concentration to an area of low concentration by passive transport.
