Glutamine and glutamate are the primary nitrogen donors for biosynthetic reactions in the cell. Glutamine is an α-amino acid that is used in the biosynthesis of proteins. Its side chain is similar to that of glutamic acid, except the carboxylic acid group is replaced by an amide. It is classified as a charge-neutral, polar amino acid. It is non-essential and conditionally essential in humans, meaning the body can usually synthesize sufficient amounts of it, but in some instances of stress, the body's demand for glutamine increases, and glutamine must be obtained from the diet. Glutamate is generally acknowledged to be the most important transmitter for normal brain function. Nearly all excitatory neurons in the central nervous system<span> are glutamatergic, and it is estimated that over half of all brain synapses release this agent. Glutamate plays an especially important role in clinical neurology because elevated concentrations of extracellular glutamate, released as a result of neural injury, are toxic to neurons</span>
It is true that a<span>n ecologist who is studying the relationships among the dominant communities in a geographical region is studying a biome.
A biome is a group of ecosystems that have the same climate and similar dominant communities, so you can see that the answer to this question is T.</span>
If lactic acid builds up in the body more quickly than it can be removed, acidity levels in bodily fluids — such as blood — spike. lactic acid buildup occurs when there's not enough oxygen in the muscles to break down glucose and glycogen.
