Primary production Gross primary production and net primary production Gross primary production (GPP) is the amount of chemical energy as biomass that primary producers create in a given length of time. (GPP is sometimes confused with Gross Primary productivity, which is the rate at which photosynthesis or chemosynthesis occurs.) 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).

MEDLINE Abstract Galanin-like peptide (GALP) is a neuropeptide involved in the regulation of food intake behavior, body weight and energy metabolism. In previous studies, we demonstrated that the intranasal administration of GALP has weight loss effects, although the mechanism of this action was not clarified.

Photorespiration Simplified photorespiration and Calvin cycle. Photorespiration (also known as the oxidative photosynthetic carbon cycle, or C2 photosynthesis) is a process in plant metabolism which attempts to reduce the consequences of a wasteful oxygenation reaction by the enzyme RuBisCO.hotorespiration also incurs a direct cost of one ATP and one NAD(P)H. While it is common to refer to the entire process as photorespiration, technically the term refers only to the metabolic network which acts to rescue the products of the oxygenation reaction (phosphoglycolate).

Plant Pigments and Photosynthesis Photosynthesis may be studied in a number of ways. For this experiment, a dye-reduction. technique will be used. The dye-reduction experiment tests the hypothesis that light and. chloroplasts are required for the light reactions to occur. In place of the electron-accepting. compound, NADP, a compound, DPIP (2,6-dichlorophenol-indophenol), will be substituted so. that when a reduction reaction has occurred, the DPIP changes from blue to colorless.

- Hypoxanthine + PRPP ---> IMP + PPi; Guanine + PRPP ---> GMP + PPi . The importance of this pathway as a source of nucleotides is shown by the consequences of a deficiency of HGPRT known as Lesch-Nyhan syndrome. This pathway reduces the need and energy expenditure of biosynthesis by maintaining nucleotide levels.

What Is Nadph in Photosynthesis? Image by Flickr.com, courtesy of Duncan Hull. Photosynthesis is the process by which plants take light energy, water and carbon dioxide and convert it to sugar and oxygen. This is done in two cycles, a Light Dependent Cycle and a Light Independent Cycle. NADPH is used in the Light Independent, or dark, cycle.oth the ATP and the NADPH are used to convert the carbohydrates created in the Light Dependent Cycle to C-C bond energy. This is done in the Light Independent Cycle, or the dark reaction cycle.

Light-independent reactions The light-independent reactions of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. These reactions occur in the stroma, the fluid-filled area of a chloroplast outside of the thylakoid membranes.here are three phases to the light-independent reactions, collectively called the Calvin cycle: carbon fixation, reduction reactions, and ribulose 1,5-bisphosphate (RuBP) regeneration. Despite its name, this process occurs only when light is available. Plants do not carry out the Calvin cycle by night.

Photosynthesis - Photolysis and Carbon Fixation - Cell Biology Photosynthesis-Photolysis and Carbon Fixation. - Cell Biology. Photosynthesis is the means that primary producers (mostly plants) can obtain energy via light energy. The energy gained FROM light can be used in various processes mentioned below for the creation of energy that the plant will need to survive and grow. Photosynthesis is a reduction process, where hydrogen is reduced by a coenzyme. This is in contrast to respiration where glucose is oxidised. The process is split INTO two DISTINCT areas, photolysis (the photochemical stage) and the Calvin Cycle (the thermochemical stage).

Cyclic Electron Transport in Photosynthesis Cyclic Electron Transport in Photosynthesis Photophosphorylation refers to the use of light energy to ultimately provide the energy to convert ADP to ATP, thus replenishing the universal energy currency in living things. In the simplest systems in prokaryotes, photosynthesis is used just for the production of energy, and not for the building of any biological molecules. In these systems there is a process called cyclic photophosphorylation, which just accomplishes the ADP to ATP process for immediate energy for these cells. This process uses only Photosystem I and the chlorophyll P700. The above sketch of the cyclic process is patterned after a visualization in Moore, et al.

Photophosphorylation In bacterial photosynthesis, a single photosystem is used, and therefore is involved in cyclic photophosphorylation. It is favoured in anaerobic conditions and conditions of high irradiance and CO 2 compensation points.TP is made by an enzyme called ATP synthase. Both the structure of this enzyme and its underlying gene are remarkably similar in all known forms of life. ATP synthase is powered by a transmembrane electrochemical potential gradient, usually in the form of a proton gradient.
