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 ...
The unit of construction costs is g g −1 (g glucose required / g biomass produced). Theoretically, if the biochemical pathways to construct all of the thousands of different compounds of an organism would be known, as well as the concentrations of all those compounds, construction costs could be simply calculated as the product of concentration and construction costs, summed over all ...
Energy intake is measured by the amount of calories consumed from food and fluids. [1] Energy intake is modulated by hunger, which is primarily regulated by the hypothalamus, [1] and choice, which is determined by the sets of brain structures that are responsible for stimulus control (i.e., operant conditioning and classical conditioning) and cognitive control of eating behavior.
All these aspects of metabolism can be represented in energy units. [citation needed] The basic model of energy budget may be shown as: P = C - R - U - F or P = C - (R + U + F) or C = P + R + U + F All the aspects of metabolism can be represented in energy units (e.g. joules (J);1 calorie = 4.2 kJ). Energy used for metabolism will be

In the United States, about 75% of the energy used is allocated to power buildings and modes of transportation; land use planning can be a useful tool in changing these aspects of energy usage in a way that would be beneficial to both residents and the ecology. [14] A sustainable urban development includes:
Building sustainability, often referred to as sustainable design, integrates strategies to lower building environmental impacts, including lowering both operational carbon, which is the emissions from energy use during a building's life, and embodied carbon, which accounts for the emissions from material production and construction.

A Zero-Energy Building (ZEB), also known as a Net Zero-Energy (NZE) building, is a building with net zero energy consumption, meaning the total amount of energy used by the building on an annual basis is equal to the amount of renewable energy created on the site [1] [2] or in other definitions by renewable energy sources offsite, using technology such as heat pumps, high efficiency windows ...
