How does light wavelength affect photosynthesis
The biological processes associated with life are achieved by sets of chemical reactions that take place inside cells. The sum of these reactions constitute cellular metabolism and they are organised into metabolic pathways. Two main types of pathways, namely catabolic and anabolic pathways, interconvert large biomolecules, such as fats, carbohydrates and proteins, and their smaller, constituent parts, such as lipids, sugars and amino acids. Catabolic pathways break down large biomolecules, releasing cellular energy in the process, while small biomolecules provide key chemical building blocks for the anabolic pathways, which use up cellular energy as they synthesise the large molecules that compose the cell.
Is photosynthesis an endergonic or exergonic reaction?
All energy yielding process are ultimately dependent upon enzymatically catalyzed redox reactions. The most important one for energy metabolism involve biological membranes with bound electron transport processes like photosynthesis and oxidative phosphorylation. Biological oxidation is the primary provider of energy for cellular anabolism, the reductive synthesis of metabolites, by furnishing mobile hydrogens, and phosporylating energy by combining hydrogens with oxygen to form water coupling this process to the production of ATP in the form of oxidative phosphorylation. Central to the oxidation-reduction processes are the containing coenzymes nicotinamide-adenine dinucleotide (NAD) and nicotinamide-adenine dinucleotide phosphate (, (C00006; oxidized form); (C00003; oxidized form; not phosphorylated at the adenosine ribosyl C2 position). Being part of the appropriate enzymes the oxidized nicotinamide ring of NAD+ or NADP+ extracts a hydride (H:-) from a wide variety of simple metabolites in a process known as dehydrogenation. The enzymes catalyzing the reduction of nicotinamide containing coenzymes are called . In a typical reaction two hydrogen atoms (including their electrons) are removed from the substrate to produce the oxidized form of the donor. The fate of the two hydrogens differs: one hydrogen with two electrons (H:-), a hydride ion, is transferred to the nicotinamide ring to produce reduced NADH or NADPH while the other hydrogen is released into solution as a free proton (H+). The generic form of a redox reaction mechanism catalyzed by enzymes with NAD as cofactor is shown.

Photosynthesis Flipbook By: Megan Tomaselli
It is a carbon dioxide requiring process that uses light energy and water to produce organin macromolecules such as glucose.
photosynthesis takes place in the leaves of the plants.
It is anabolic, meaning that small molecules are combined.
it is also endergonic, meaning that it stores energy.
