Each cycle in the transport process results in the conversion of ATPto ADP and Pi, (free-energy change)the electrogenic pumping of Na and K. Brain-kidney2/3 ATP consumed for Na and K WHERE ATP USED ATP for muscle contraction Reading assignment page 186 Transphosphorylation btwn nucleotides All dNTPsenergetically equal to ATP ATP is the primary high-energy phosphate compound produced by catabolism, in the processes of glycolysis, oxidative phosphorylation, and, in photosynthetic cells, oxidative phosphorylation, and, in photosynthetic cells, photophosphorylation.

Complexity: entropy G the change in Gibbs free energy of thereacting system H the change in enthalpy of the system. G= H-T S H the change in enthalpy of the system. T the absolute temperature, S the change in entropy of the system.
The other product, Pi, is also resonance oduct, Pi, is also resonance stabilized. Others: Thioesters Ester with a S instead of O Acetyl-CoA has a key role in the Acetyl-CoA has a key role in the metabolism. Standar free energy change is high Energy from ATP by P transfer Energy transfered by group, in some processes ATP directly hydrolyzed and released energy used for motion. Ex: muscles, G-prot. Classification of compound with P Two High-energy compounds any phosphorylated compound synthesized by coupling the synthesis to the breakdown of another phosphoryl-ated compound with a more negative free energy of hydrolysis.

Y aquí amigos, es donde empieza esa montaña rusa de emociones, en donde por medio de flashbacks vamos averiguando el pasado de Jude, vamos leyendo su presente y como esto afecta su futuro, no quiero contarles mucho porque vale la pena ser maltratado emocionalmente por este libro, pero si les voy a decir que me mantuvo en las lágrimas y que frecuentemente pensaba, el mundo es tan cruel, odio a las personas, y es que aunque solo es un libro, es un libro realista, cruel y tajante pero realista. Y es que no puedo decirles que el libro esta basado en la amistad, el amor, y la búsqueda del bienestar personal, pero les estaría mintiendo y dándoles una expectativa alejada de lo que Tan poca vida es, el libro esta basado en el sufrimiento, en el dolor emocional y físico, en el vació de la rutina en lo más gris de la vida y hasta que punto se puede soportar, ya sé que suena bastante trágico, pero es lo que es, y eso es lo que lo hace tan único. Me voy a tomar un pequeño tiempo en hablar de Jude, el protagonista de esta historia, y en decir cual importante es su historia de vida, no diré nada acerca de esta pero si enfocaré en el hecho de que la salud mental es importante, igual o a veces hasta más que la salud física, y como a veces no se le da la importancia y el tratamiento debido, igual aquí me lo tomo bastante personal, pero es muy importante estar bien, y cuidarse.
