Answer:
For chemical reactions where the free energy of the reactants is much greater than the free energy of the products (DGo' < 0), the reaction proceeds spontaneously and the net result is a large ratio of product to reactant (large Keq).
Explanation:
Carbs-Monosaccharide, Lipid-Triglycerides, Protein-Amino Acids, Nucleic Acids-Nucleotides!
It's both B.They can never be depleted and C.They are replaceable by natural means.
Stars are classified based on the spectral type (i.e. a means to measure the photospheric temperature and density by getting information about the ionisation state).
Under the Morgan–Keenan (MK) system using the letters O, B, A, F, G, K, and M, a sequence from the hottest (O type) to the coolest (M type) (Harvard Spectral classification based on the surface temperature of the stars). A luminosity class is added to the spectral class using Roman numerals (Yerkes Spectral classification). This is based on the width of certain absorption lines in the star's spectrum (0 or Ia+ - hypergiants, I - supergiants, II - bright giants, III - regular giants, IV - sub-giants, V - main-sequence stars, sd - sub-dwarfs, and D - white dwarfs).
At the centre is a sugar molecule, ribose (the same sugar that forms the basis of RNA). Attached to one side of this is a base (a group consisting of linked rings of carbon and nitrogen atoms); in this case the base is adenine. The other side of the sugar is attached to a string of phosphate groups. These phosphates are the key to the activity of ATP.
