Building materials for cells.
Cells have organelles such as mitochondria, lysosomes, vesicles, etc.
It is estimated that the body has over ten trillions cells
Carry oxygen, build tissue, copy DNA for the next generation and do the work needed by the body.
Deoxyribonucleic acid contains the blueprint for proteins and replication of itself mRNA transcribes DNA, tRNA translates mRNA into proteins. A pattern on nucleotide on a DNA strand is called a gene.
The Central Dogma of molecular biology is: DNA codes for RNA which codes. for proteins Not all genes are expressed for the production of proteins, some have other tasks like making RNA.
Some proteins are structural.
Some proteins are made of hundreds or thousands of amino …show more content…
Proteins contain nitrogen.
Some proteins are regulatory such as enzymes.
Enzymes assists in functions.
DNA contains the master plan for enzyme creation.
Enzymes assist in DNA replication.
They facilitate chemical reactions that would be too slow to support living systems.
Enzymes have increased the rate of a biochemical reaction by a billion-fold +.
Possibly have binding sites that hold other molecules.
Provide an ATP binding site.
They contain carbon, hydrogen, and oxygen like the carbohydrates.
Carbs are compounds that provide energy.
The compound has carbon, hydrogen and oxygen, the ratio is two hydrogens for every oxygen atom.
Carbohydrates can be traced back to photosynthesis.
Take the form of starches, sugars and cellulose.
They contain carbon, hydrogen, and oxygen like the lipids.
Lipids include fats, oils, waxes, and sterols.
Use the same elements as carbs.
Made of glycerol and 3 fatty acids. (Triglyceride lipid)
Steroids are a type of lipid
Lipids include phospholipids that make cell membranes.
Proteins are made of thousands of amino acids.
Amino acids contain an amino group and carboxyl group.
There are 20 amino acids, these are distinguished by the
