Compare and contrast the chemical composition and structure of the cytoplasmic membranes found in bacteria and archaea. what is the advantage of the archaeal membranes in relationship to the types of environments archaea may inhabit?

Bacteria have a phospholipid bilayer whereas archaea have a monolayer. This monolayer allows archaea to be heat-resistant

Explanation:

Unlike the lipids present in bacteria and Eukarya, in which the ester binds fatty acids to glycerol, Archaea lipids contain ether type bonds between glycerol and the hydrophobic part of the chain. Archaeological lipids lack fatty acid side chains and are formed by repeated hydrophobic isoprene structures using 5 carbon chains. The arcade cytoplasm membrane can be constructed from glycerol having chains of 20 or 40 carbons (called phthanyl groups and diglycerol tetraethers, respectively).

In the tetraeter lipid, the ends of the carbon chains are covalently bonded, this forms a lipid monolayer instead of a lipid bilayer.

The membrane compacted by the monolayer is extremely resistant to heat denaturation and, therefore, is considered hyperthermophilic (prokaryotic organisms that can grow at temperatures above 80 ° C)

n+h→nh3

we must remember that nitrogen and hydrogen are both diatomic molecules in their standard gas form. this adjusts the equation to

n2+h2→nh3

now we need to adjust coefficients in order to balance the atoms on each side of the equation. currently we have 2 atoms of nitrogen and 2 atoms of hydrogen on the reactant side and 1 atom of nitrogen and 3 atoms of hydrogen on the product side.

we can balance the hydrogens by placing a coefficient of 2 in front of ammonia and a coefficient of 3 in front of the hydrogen.

n2+3h2→2nh3

this gives us 6 hydrogen on each side and coincidentally the nitrogens now equal 2 on each side.
