As an energy source, biomass can either be used directly via combustion to produce heat, or indirectly after converting it to various forms of biofuel. Conversion of biomass to biofuel can be achieved by different methods which are broadly classified into: thermal, chemical, and biochemical methods.rops, such as corn and sugar cane, can be fermented to produce the transportation fuel, ethanol. Biodiesel, another transportation fuel, can be produced from left-over food products like vegetable oils and animal fats. Also, biomass to liquids (BTLs) and cellulosic ethanol are still under research.
Protein-energy wasting (PEW), a term proposed by the International Society of Renal Nutrition and Metabolism (ISRNM), refers to the multiple nutritional and catabolic alterations that occur in chronic kidney disease (CKD) and associate with morbidity and mortality.
Adenosine Triphosphate (ATP) is the immediate source of (chemical) energy for muscle contraction. Very little ATP is stored in muscle fibres (= ' muscle cells '), only enough to power muscle contractions for a few seconds.The ATP in muscles must be constantly replenished as it is used for various processes.his (creatine phosphate reaction) source can typically release enough energy for muscle contraction for up to about 15 seconds, e.g. to run for a short time / distance. This process of releasing ATP and hence energy, does. so can be described as anaerobic. This is known as the Alactic or Creatine Phosphate (CP) System.
