What is the name of the macromolecule in which phosphorus is found?
2 Answers
ATP (adenosine triphosphate) and ADP (adenosine diphosphate)
Explanation:
ATP molecule (C10H16N5O13P3) and ADP molecule (C10H16N5O13P2) are macromolecules containing phosphorus.
They are very important in photosynthesis.
Phosphorus if found in DNA, cell membranes and ATP.
Explanation:
In living organisms phosphorus is largely observed as a phosphate group, see the picture below.
As can be seen, the phosphate group has a negative charge. This makes this part of a larger molecule hydrophilic (it can form hydrogen bonds and can dissolve in
DNA and other information carriers
DNA are large molecules that have a certain sequence, which codes for the make of proteins in the cell. These DNA strands consist out of 4 different bases placed with a certain sequence along a line.
In the picture above a very schematical single DNA strand is showed. The 4 different bases are coloured and connected to the backbone (the black horizontal line) in a certain way. This backbone is build up out of a lot of phosphate groups! This makes DNA negative and hydrophilic on the outside.
Cell membranes
Every cell has a membrane around it. You can see this like a border to enter or leave the cell. This border consists out of many phospholipids. These are showed below.
The hydrophilic head of a phospholipid is made up from the negatively charged phosphate group.
ATP, the energy storage
Certain molecules in the cells are used for the storage of energy. This energy can be used to activate other processes in the cell. An example of an energy storage molecule is ATP (adenosine triphosphate), which consists out of 3 phosphate groups!
