From Wiktionary under the GNU Free Documentation License. Biochemistry is the study of the chemical processes in living organisms. It deals with the structure and function of cellular components such as proteins, carbohydrates, lipids, nucleic acids and other biomolecules. Among the vast number of different biomolecules, many are complex and large molecules (called polymers), which are composed of similar repeating subunits (called monomers). Each class of polymeric biomolecule has a different set of subunit types. For example, a protein is a polymer whose subunits are selected from a set of 20 or more amino acids. Biochemistry studies the chemical properties of important biological molecules, like proteins, and in particular the chemistry of enzyme-catalyzed reactions. The biochemistry of cell metabolism and the endocrine system has been extensively described. Other areas of biochemistry include the genetic code (DNA, RNA), protein synthesis, cell membrane transport, and signal transduction. Since all known life forms that are still alive today are descended from the same common ancestor, they have generally similar biochemistries. It remains unknown whether alternative types of biochemistries are possible, or practical, given the chemical elements composing the matter of the Universe. An emerging thesis, called "carbon chauvinism," holds that only carbon-based compounds are available to be part of a real biochemistry. From Wikipedia under the
GNU Free Documentation License What is the biochemical purpose for the production of lactate in muscle cells? Q. What is the biochemical purpose for the production of lactate in muscle cells? It replaces pyruvate as a subsstrate for the pyruvate dehydrogenase complex. It is produced to reoxidize cytoplasmic NADH under anaerobic conditions It is produced as a fuel molecule for the Cori cycle. It decreases the pH of the muscle cell, thereby increasing release of oxygen from hemolglobin. Its production enhances the activity of the citric acid cycle.

It is produced to reoxidize cytoplasmic NADH under anaerobic conditions Glycolysis needs NAD+ to continue its operation. Under anaerobic conditions fermentation oxidizes NADH to NAD+ Answered by Mark C - Thu Oct 23 13:14:08 2008 Do all biochemical reactions happened in our body have a negative free energy?? Q. I am a high school student. Yesterday, my teacher teacher gave us a question written: Does all the biochemical reactions happened in our body have a negative free energy? Explain and support your answer. I don;t know how to answer it. Any one can help. Thx in advance!! Asked by Answersbot - Thu Nov 1 08:27:50 2007 - - 1 Answers - 0 Comments A. Mmmm ok im going to have a shot at this. I assume your teacher is talking about Gibbs free energy, and probably knows a bit about Schrodinger who blabbed on at length about life "feeding off' negative entropy to stay alive. What i would say is that in order for a process to be spontaneous at a fixed temperature Gibbs free energy must be negative (or zero in some cases) . If you want more on this look up the second law of thermodynamics and the relationship of entropy to gibbs). Now assuming you are a mammal then your temperature is fixed, then all favoured reactions will have negative Gibbs free energy.

Q. Please help with a complete answer and explain. ahh im so confused! Asked by Blah B - Sat Mar 8 09:35:35 2008 - - 2 Answers - 1 Comments A. Biochemical relationships are limited to comparing living life forms and their genetic relationships. Extinct forms of life must be compared using more traditional methods.
