This is caused by the fact that the remaining cyclic AMP continues to activate protein kinase, which in turn activates phosphorylase kinase. Glycogen phosphorylase is in trun activated by phosphorylase kinase. Sustained activation of phosphorylase results in continued mobilization of glucose residues from glycogen stores in the liver. You are trying to purify chlorophylls a and b from some leaves. You would want to use acetone because it is an organic solvent and the chlorophylls, which are hydrophobic in nature, would be soluble in acetone.
Chlorophylls are hydrophobic due to their porphyrin ring and phytol tail.
Isoleucine both Aspartate g Phenylalanine both 5. Essentially, blocking a biochemical pathway at any of its steps may lead to increased concentration of any of the precursors or members of the pathway. In a pH gradient, DNP binds a proton on the acidic side of the membrane and diffuses through to release the proton on the basic side. Suppose chloroplasts are incubated in the presence of light and carbon dioxide and are carrying out carbon fixation at a high rate. DNP is then added.
