The biomass that is used as input materials consists of recently living (but now dead) organisms, mainly plants. [2] Thus, fossil fuels are not regarded as biomass under this definition. Types of biomass commonly used for bioenergy include wood, food crops such as corn, energy crops and waste from forests, yards, or farms. [3]
Biomass (in the context of energy generation) is matter from recently living (but now dead) organisms which is used for bioenergy production. There are variations in how such biomass for energy is defined, e.g. only from plants, [8] or from plants and algae, [9] or from plants and animals. [10]
Biomass is a term used in several contexts: in the context of ecology it means living organisms, [1] and in the context of bioenergy it means matter from recently living (but now dead) organisms. In the latter context, there are variations in how biomass is defined, e.g., only from plants, [ 2 ] from plants and algae, [ 3 ] from plants and ...
Starch, made of amylose and amylopectin, plants energy storage. [2] Glycogen, energy in animals. [2] Cellulose, a biopolymer, found in the cell walls of plants. [2] Fatty acid, two types, saturated fat and unsaturated fat (oil), are stored energy. [2] Essential fatty acid, needed but not synthesized by the human body. [2]
The global biomass broken down by kingdom and into taxonomic groups for animals. [1] The estimates for bacteria and archaea have been updated to 30 billion tonnes C combined since this figure was made. [20] Most of the global biomass is found on land, with only 5 to 10 billion tonnes C found in the oceans. [24]
Bioenergetics is a field in biochemistry and cell biology that concerns energy flow through living systems. [1] This is an active area of biological research that includes the study of the transformation of energy in living organisms and the study of thousands of different cellular processes such as cellular respiration and the many other metabolic and enzymatic processes that lead to ...
Gross primary production (GPP) is the amount of chemical energy, typically expressed as carbon biomass, that primary producers create in a given length of time.Some fraction of this fixed energy is used by primary producers for cellular respiration and maintenance of existing tissues (i.e., "growth respiration" and "maintenance respiration").
The energy for ATP resynthesis comes from three different series of chemical reactions that take place within the body. Two of the three depend upon the food eaten, whereas the other depends upon a chemical compound called phosphocreatine. The energy released from any of these three series of reactions is utilized in reactions that resynthesize ...
