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.
ATP and creatine phosphate (or phosphocreatine, or PCr) make up the ATP-PCr system. it is the immediate energy system. Creatine phosphate (PCr) is a high-energy compound. When evercise intensity is high, or energy needs are instantaneous, creatine phosphate stored in muscle is broken down to provide energy to make ATP.hen ATP is broken down, it gives energy for muscle contraction. It is the only molecule that can supply the energy used in the contraction of muscle fibres and can be made in three ways: the creatine phosphate system which is also called Phosphocreatine, the lactic acid energy system and the aerobic energy system.
