And the body of the plant stores that energy, becoming a useful source of fuel. Petroleum - Petroleum (oil) is a fossil fuel formed from the remnants of ancient marine organisms like algae. Petroleum is a useful source of chemical energy because, in the presence of oxygen, it requires ...
In this context the term "thermochemical energy storage" includes chemical storage (e.g. hydration reaction of a salt) and sorption storage (e.g. adsorption and absorption processes). As a positive outcome of the increased research activities, a wide range of storage materials have been ...
active transport is the transport of particles against the concentration gradient. This means that the particles are moved from an area oflowconcentration to an area ofhighconcentration. Because of this, chemical energy is spent to move the particles to an area that is already saturated or dense...
NADPH is an energy-carrying molecule and a potent reducing agent. Similar to ATP the NADPH stores chemical energy, which is used when making glucose and other organic compounds. Calvin Cycle, in particular, is a pathway wherein CO2is made into sugar, and ATP and NADPH supply the energy. ...
The marketing funnel is a critical piece of the marketing process. It outlines the most straightforward journey customers might take in their path to purchase. Ultimately, the marketing funnel is a helpful framework for connecting and engaging with customers along their journey. ...
Although indirect, Scope 2 emissions present both a major source of organizational emissions and a major opportunity for improved sustainability when companies reduce energy consumption or turn to low-carbon resources such as solar energy, wind power or nuclear energy. ...
Electrochemical cells that produce electric energy from chemical energy are the basis of primary and secondary (storage) batteries and fuel cells. Other electrical phenomena of interest in chemical systems include the behavior of ionic solutions and the conduction of current through these solutions, the...
Energy: Solar power and wind power are close substitutes in the renewable energy sector. Both provide sustainable alternatives to fossil fuels but differ in terms of geographic feasibility, upfront installation costs, and ongoing maintenance. For instance, solar power is more viable in regions with ...
and other animals use cellular respiration to digest food. The adenosine triphosphate is a chemical compound that provides energy to drive various processes in the living cells. The production ofadenosine triphosphatein aerobically-respiring animals is coupled withoxidative phosphorylation(a process in whic...
Carbon is one of the chemical elements found in nature. A chemical element refers to the pure substance of one type of atom. At present, 94 are natural elements whereas 24 are synthetic. Carbon is one of the most common elements in living things, together with oxygen, hydrogen, and nitroge...
