O O O OO Activity (% Max.) Using your knowledge of aspartyl proteases, develop a plausible explanation for why protein activity changes when pH is increased or decreased from pH 4, as shown in the graph. 000 06 08 09 Hd Which statements are true? O The protein is active when one asp residue is protonated and the other is deprotonated. Both asp residues are protonated at more basic pH values. Active aspartyl proteases have only one asp residue in the active site. Only one asp side chain is protonated at low pH (below pH 3.5). Both asp side chains are deprotonated at higher pH values.
Nucleotides
It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
Nucleic Acids
Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.
