This is a very interesting question, as it could have two different answers.
On one hand, we have DNA, which is important for obvious reasons.
On the other, we have ATP, which provides energy for every cell on the planet.
Since there are other ways to store genetic information besides DNA, I would deem ATP as the most important molecule in the human body, as nothing can survive without energy.
To the extent of a layman's understanding, the macro-molecule that has absolutely the most import to life may very well be that of water. Following behind and "running" a close second may very well be macro-molecules of proteins; all genes in the genomes of organic life contain the "blueprints" for synthesis of proteins.
Carbohydrates are the most important organic compounds in living organisms. Almost all organisms use carbohydrates as a source of energy.
water or H2O
Water , because all life requires it.
Carbon
Glucose is considered a very important molecule for living beings because it provides us energy & we use most of the energy in the form of glucose(the ultimate source of energy. bhuvan sorout
DNA
Its most important function is as a precursor to ATP, which is the general "energy molecule" within a cell.
All the sphere's are important for the human life.
The most important thing about Venus is probably that there is no life on it.
Cholesterol is the most important steroid molecule.
There is no such compounds which are declared as important. Water molecule is one of the essential inorganic compounds to human, animals and plants.
ATP
The most important thing in life is to always look on the bright side of it.
Glucose is considered a very important molecule for living beings because it provides us energy & we use most of the energy in the form of glucose(the ultimate source of energy. bhuvan sorout
It is the most stable form of oxygen as an element.
water air and food are the most important things water, sunlight, and carbon are the most important for life
Some of life's most important virtues are love, respect, and peace. These are important to maintain good relationships and live a happy life.
Water is one of the most important compounds neceesary for life.
No. Narcissists think that they are the most important thing in life.
DNA
Its most important function is as a precursor to ATP, which is the general "energy molecule" within a cell.
