Central nervous system disturbances. It assists in energy transformation in brain and nerve tissue hence, the functioning of the central nervous system. When vitamin B-6 is lacking, convulsive seizures occur in both human infants and experimental animals.

In the liver, the ketone bodies suffer no transformation, and are excreted into the blood. The normal contents of ketone bodies (as acetoacetate or P-hydroxy-butyrate) amount to mere 0.1-0.6 mmol/ litre). Other tissues and organs (heart, lung, kidney, muscle, and nervous tissue), as distinct from the liver, utilize the ketone bodies as energy substrates. In the cells of these tissues, acetoacetate and 1-hydroxybutyrate enter ultimately the Krebs cycle and burn down to C02 and H,0 to release energy. 

Plants, as a rule, tend to grow upwards towards the light, transforming available moisture and solar energy into complex sugars that build tissue. While the range of plant adaptations to meet this bottom-line need is vast, those of turfgrasses are specific and notable. 

Figure 2.1 The Green Man s sketch of the living he schematizes a system composed by only one tissue S S decays into a P, but due to the internal activity of the system, the nutrient A is converted into the tissue S again. This pictorii representation corresponds to a definition of life that reads a physical system can be said to be living if it is able to transform external matter/energy into an internal process of self-maintenance and self-generation.
