Hydrogen Bonding as Essential for Life

.
             Rusty L. Myers (2006) Defines high heat specific capacity as the measure of energy needed to change the temperature of 1g of a substance by 1C. Hydrogen bonding increases the strength between water molecules that is why water requires a lot of energy to raise the temperature compared to other fluids without hydrogen bonds. This is very useful when actively the body is maintaining its temperature at 37C. Having 37C as the core temperature of the human body suggested by Steven Heymsfield (2005) means that metabolic reaction can occur efficiently as enzymes are able to work at their optimum temperature Fig. 3 stated by Dr. S. Shanmugam (2009) that happens to be similar to the core body temperature. A normal human body consist of 70% water it therefore can be said water is resistant to fluctuation to the core body temperature due to the high energy requirement to change the temperature of water.
             Solid is denser than a liquid due to the particles being tightly packed together normally however it is suggested by Alex Kaivarainen (2008) that in terms of water Ice is less dense aqueous water and therefore ice floats on aqueous water this is because in ice molecules the hydrogen bonds between the water molecules create a lattice structure Fig. 4 that increases the distance between the molecules therefore less water molecules per volume exist in a solid form than as a liquid form as the hydrogen bond in ice is saturated. Sub-terrestrial organisms such as polar bears habitat is on the ice and if ice did not float than the habitat for the organism would not exist which means biodiversity would be affected. .
             Through transpiration Melvin T. Tyree, ‎Martin H. Zimmermann (2002) suggest that cohesion allows water movement up the plant xylem to the leaves from the roots of plants to be used in respiration and other metabolic reactions. Plants would not be able to transport water if cohesion were not to happen, as the strand of water would break.

1. Hydrogen Bonding in Water

HYDROGEN BONDING IN WATER Water is a compound that goes against many trends, and this is obvious when we look at its physical properties. ... Water is the only compound that does this, due, once again, to its hydrogen bonding. ... Water is a very frequently used polar solvent, can act as an acid or base depending on the situation, is found under its three states of matter on the Earth, and is essential to the forms of life on Earth ( it is important to state this, as other forms of life may be based on other elements, and may not need water to survive ). ... Hydrogen bonding is what enables...

2. Water

It has many properties that render it essential for the sustenance of life. ... Water will dissolve many substances because of its ability to hydrogen bond. ... When ice forms on the surface of a pond, it floats and forms an insulating layer, so that beneath the ice, the water remains liquid and life can continue. Hydrogen bonding in water also allows surface-dwellers to flourish. ... Hydrogen bonding gives water the cohesive properties it needs to stick to the sides of its container and narrow channels in soil. ...

3. monomers the basis of life

Chitin is structurally very similar to cellulose, and forms bundles of long parallel chains which are an essential part of the arthropod skeleton. ... Quaternary structure describes the way two or more polypeptide chains are held together by hydrogen bond and ionic bonds and by hydrophobic interactions, e.g. haemoglobin, which consists of four polypeptide chains each of which is combined with an iron-containing haem group. ... Adenine is always paired with thymine by two hydrogen bonds, and guanine is always paired with cytosine by three hydrogen bonds. ... It can be seen from the informati...

The sequence specifies the exact genetic instructions that makes up the "blue-print" for life and distinguishes one species from another. ... The two DNA strands are separated along the hydrogen bonds that link the paired bases, much like opening a zipper. ... Nucleotides, added one by one to the 3" end, are paired by hydrogen bonding to an exposed base on the DNA template. ...

6. DNA and the Transfer of Information

This helps to make DNA a very stable molecule which is an essential feature for a molecule, which carries and transfers vital information. ... DNA is a large molecule therefore it can store large amounts of information, this is essential as the organisms entire genetic code and instructions for life in a sense need to be stored in a secure molecule which easily allows for replication. Guanine will always pair with cytosine by means of three hydrogen bonds. Adenine will always pair with thymine by the means of 2 hydrogen bonds. ... This is an essential way by which information is transferred ...

7. Atmospheric Structure

These wavelengths are harmful to life because they can be absorbed by the nucleic acid in cells. Increased penetration of ultraviolet radiation to the planet's surface would damage plant life and have harmful environmental consequences. ... These gases may have consisted of hydrogen (H2), water vapor, methane (CH4) , and carbon oxides. Prior to 3.5 billion years ago the atmosphere probably consisted of carbon dioxide (CO2), carbon monoxide (CO), water (H2O), nitrogen (N2), and hydrogen. ...

8. Photosynthesis

Photosynthesis and respiration are two very complex and they could only be considered reversible in the broadest ecological sense.Priestly and Ingenhouz overlooked a fact about respiration, they only said that animals respire and make air unfit for life, and did not say anything about plant cells, that left in a dark area will run out of air, and will die also. ... The hydrogen ions and electrons are used in further photosynthetic reactions, but not as independent particles. ... Once the electron carriers receive hydrogen ions and electrons, they become chemically reduced, when they give up th...
