What makes a molecule aromatic?
In organic chemistry, an aromatic molecule is one that is cyclic, planar (flat), with an uninterrupted cloud of pi electrons. Typically, in order to be aromatic the molecule must follow Huckel's Rule, which states that in order for a molecule to be aromatic it must contain a certain number of pi electrons (4n + 2 rule, in which n is number of pi-bonds or pi-lone pair electrons).
In cellular respiration, how many ATP are produced by one molecule of glucose.
Typically, one molecule of glucose will produce about 38 ATP: 2 from glycolysis (when ATP and pyruvic acid are produce), 2 from the krebs cycle (produced in the mitochondria, consuming oxygen and producing water and carbon dioxide as waste products, ansd converting ADP to energy-rich ATP), and 34 from the electron transport chain.
Solve: (x-1)^2 = (4(sqrt(x-4))^2
x^2-2x+1 = 16(x-4) x^2-2x+1 = 16x - 64 x^2-18x+65 = 0 (x-5)(x-13) = 0 x=5 or x=13
