Photosynthesis (/ ˌ f oʊ t ə ˈ s ɪ n θ ə s ɪ s / FOH-tə-SINTH-ə-sis) [1] is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their metabolism.

The mixed acid fermentation pathway in E. coli. [1] [2] End products are highlighted in blue.In biochemistry, mixed acid fermentation is the metabolic process by which a six-carbon sugar (e.g. glucose, C 6 H 12 O 6) is converted into a complex and variable mixture of acids.
The light-harvesting system of PSI uses multiple copies of the same transmembrane proteins used by PSII. The energy of absorbed light (in the form of delocalized, high-energy electrons) is funneled into the reaction center, where it excites special chlorophyll molecules (P700, with maximum light absorption at 700 nm) to a higher energy level.
The natural fermentation product of these bacteria, hydrogen gas, can be harnessed as a natural gas energy source. [6] [7] Photofermentation via algae instead of bacteria is used for bioethanol production, among other liquid fuel alternatives. [8] Basic principles of a bioreactor. The photofermentation bioreactor would not include an air pathway.
UBS recommends tech, financials, industrials and utilities stocks going into 2025, citing continued AI growth and pro-business policies under Trump.
5. Stay Hydrated. Staying hydrated is essential for keeping your body and mind feeling energized. Water plays a critical role in many bodily functions, including transporting oxygen and building ...
The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, producing large amounts of energy (ATP). Respiration is one of the key ways a cell releases chemical energy to fuel cellular activity. The overall reaction occurs in a series of biochemical steps, some of which are redox reactions.
