Offers protection from the outside environment photosynthesis occurs at the cell levelwhich organelle is necessary for photosynthesis.

What percentage of human cells made up of macromolecules provide energy. Correct answer to the question What 2 macromolecules make up a cell membrane. Macromolecules are giants of the atomic world. Proteins nucleic acids and most carbohydrates the polysaccharides are macromolecules formed by the joining polymerization of hundreds or thousands of low-molecular-weight precursors.

Many macromolecules are polymers of smaller molecules called monomers. A macromolecule is a very large molecule such as a protein. Coli cell in aerobic balanced growth at 37C in glucose minimal medium with doubling time of 40 minutes and 1 pg cell wet weight 09 μm3 cell volume.

Mitochondria singular mitochondrion are often called the powerhouses or energy factories of a cell because they are responsible for making adenosine triphosphate ATP the cells main energy-carrying molecule. In mammalian cells the fraction taken by RNA decreases to about 4 while the fraction of lipids increases BNID 111209. What are Macromolecules.

Most of the human body is made up of water H 2 O with bone cells being comprised of 31 water and the lungs 83. Overall macromolecular composition of an average E. Macromolecules are so huge that these are made up of more than 10000 or more atoms.

In combination these biological macromolecules make up the majority of a cells dry mass. Herman Staudinger coined it in 1920. Therefore it isnt surprising that most of a human bodys mass is oxygen.

However the characteristics of substances other than pure elementsincluding the materials from which living cells are made. What macromolecules are cells mainly made up of. The smallest particle of an element that still retains its distinctive chemical properties is an atom.
