Answer: 4.
This is a free search engine maintained by the United States National Library of Medicine.
It is used for accessimg and searching of MEDILINE database.
Medline is an acronym for (Medical Literature Analysis and Retrieval System Online) it is conprehensive bibilography of research materials in fields of biomedicine and life sciences.It contains abstracts and references of related journals.
It is an online repository for biomedical research materials
It also helps to promotes the concept of evidence based medicine.(The concept of clincal medicine that depends on the combination of available research evidences with patients values and clincal research.)
Therefore the use of Pubmed is to gain access into all the information above in the MEDLINE.
Glucose turns into ATP or ENERGY during the process of cellular respiration ..
<span>The glucose is broken down into 2 molecules of pyruvate, which are two smaller molecules. A net yeild of 2 ATP and 2 NADH result. Each pyruvate is connected to a coenzyme. The resulting molecule is called Acetyl CoA. That reaction also gives off 2 molecules of C02. The Acetyl CoA enters the Krebs Cycle, from which (through a series of steps), 2 more ATP, 6 NADH, 2 FADH2, and 6 CO2 are formed. The 6 NADH and FADH2 (which are coenzymes) move on to the electron transfer chain. Here, they give up their H+ and electrons to the chain. The electrons reduced the proteins on the chain, allowing H+ from outside the cell to be brought in. Bringing this H+ into the cell builds up the concentration. When the concentration gets high enough, the H+ wants to go back out of the cell. The only way to do this is through the ATP synthase. When is passes through this, the synthase combines an ADP with an inorganic phosphate, forming ATP. The typical yeild is 32 ATP from this, giving a total of 36 when you add in the ATP from glycolysis and the Krebs cycle.</span>
