Capture of energy from sustainable energy sources (including light) (Fig. (Fig.1a), 1 a), water splitting (Fig. (Fig.1b), 1 b), and even the initial steps of CO 2-fixation (Fig. (Fig.1c) 1 c) can now be replaced by non-biological processes, but full reduction of carbon (Figs. (Figs.1d 1 d and e) and the synthesis of complex molecules (Fig. (Fig ...
5.1: Energy in Biological Systems – Introductory Biochemistry
Movie 5.1: ATP: The fuel of the cell. Formation of triphosphates, like ATP, is essential to meeting the cell''s energy needs for synthesis, motion, and signaling. In a given day, an average human body makes and breaks down more than its weight in triphosphates.
Water: Its Properties, Distribution, and Significance
Non-humic substances: The organic substances other than humic substances include amino acids, carbohydrates, oils, and resins.

ATP cycle and reaction coupling | Energy (article) | Khan Academy
ATP is hydrolyzed to ADP in the following reaction: ATP + H 2 O ⇋ ADP + P i + energy. Note: P i just stands for an inorganic phosphate group (PO 4 3 −) . Like most chemical reactions, the hydrolysis of ATP to ADP is reversible. The reverse reaction, which regenerates ATP from ADP and P i, requires energy.

Frew et al. predict that to support an 80% renewable electricity portfolio in the US, between 0.72 and 11.2 petajoules (PJ; 1 PJ = 1 × 1015 J or 277.8 gigawatt-hours (GWh)) of storage are needed [2, 5]. By contrast, Shaner et al. predict that 20 PJ of storage, about 12 hours of supply, will be needed to support 80% renewables [6].

Lipids include a diverse group of compounds that are largely nonpolar in nature. This is because they are hydrocarbons that include mostly nonpolar carbon–carbon or carbon–hydrogen bonds. Non-polar molecules are hydrophobic ("water fearing"), or insoluble in water. Lipids perform many different functions in a cell.
