A Ramachandran plot (also known as a Ramachandran map or a Ramachandran diagram or a [φ,ψ] plot), developed by Gopalasamudram Narayana Ramachandran and Viswanathan Sasisekharan is a way to visualize dihedral angles ψ against φ of amino acid residues in protein structure. . It shows the possible conformations of ψ and φ angles for a ...Coupling to other metabolic pathways . These reactions are closely coupled to the thylakoid electron transport chain as the energy required to reduce the carbon dioxide is provided by NADPH produced in photosystem I during the light dependent reactions.The process of photorespiration, also known as C2 cycle, is also coupled to the calvin cycle, as it results from an alternative reaction of the ...

molecule of glucose being oxidized • The remaining steps release enough energy to shift the balance sheet to the positive side. This part of the glycolytic pathway is called as the payoff or harvest stage. • Since there are 2 GAP molecules generated from each glucose, each of the remaining reactions occur twice for eachThis RNA molecule then moves from the nucleus to the cell cytoplasm, where the actual the process of protein synthesis take place. What is protein synthesis - The details! All cells function through their proteins. Protein function is defined by their molecular function , localization within cell and involvement in a particular biological ...In addition to carbohydrates, fats and proteins are the other two macronutrients required by the human body. Fats, a subgroup of lipids, are also known as triglycerides, meaning their molecules are made from one molecule of glycerol and three fatty acids. Fats in the body serve mainly as an energy storage system. Tyrosine-kinase receptors consist of two polypeptides that join when activated by a signal molecule. Ion channels are found on both the plasma membrane and the endoplasmic reticulum. Cyclic AMP binds to calmodulin. Kinases are enzymes that phosphorylate other molecules.Sometimes polymers are also known as macromolecules or large-sized molecules. Usually, polymers are organic (but not necessarily). A monomer is a molecule that is able to bond in long chains. Here is a monomer: Here is a polymer: A polymer can be made up of thousands of monomer. This linking up of monomers is called polymerization.Biological macromolecules all contain carbon in ring or chain form, which means they are classified as organic molecules. They usually also contain hydrogen and oxygen, as well as nitrogen and additional minor elements. Four Classes of Biological Macromolecules. There are four major classes of biological macromolecules: carbohydrates; lipids; proteins The Krebs cycle, also known as the tricarboxylic acid (TCA) cycle or citric acid cycle, is the series of chemical reactions that generates energy through the oxidation of acetate. It was identified in 1937 by Hans Krebs, who was responsible for elucidating most of the pathway.

It's known for sure that chocolate contains mood-boosting caffeine and phenylethylamine, a substance called the "love molecule" that simulates the feeling of being in love. It also contains theobromine, a substance related to caffeine, that acts as a relaxant rather than a stimulant.The movement of macromolecules such as proteins or polysaccharides into or out of the cell is called bulk transport.There are two types of bulk transport, exocytosis and endocytosis, and both require the expenditure of energy (ATP). In exocytosis, materials are exported out of the cell via secretory vesicles. In this process, the Golgi complex packages macromolecules into transport vesicles ...This negative end makes the surrounding molecules have an instantaneous dipole also, attracting the surrounding molecules' positive ends. This process is known as the London Dispersion Force of attraction. The ability of a molecule to become polar and displace its electrons is known as the molecule's "polarizability." The more electrons a ...

Effect of Intermolecular forces on Melting Points and Boiling Points of Molecular Covalent Substances. Since melting or boiling result from a progressive weakening of the attractive forces between the covalent molecules, the stronger the intermolecular force is, the more energy is required to melt the solid or boil the liquid.This method (also known as step-growth) requires that the monomers possess two or more kinds of functional groups that are able to react with each other in such a way that parts of these groups combine to form a small molecule (often H 2 O) which is eliminated from the two pieces. The now-empty bonding positions on the two monomers can then ...

molecule transmitter, but in some cases a peptide is the primary transmitter at a synapse. Single ions, such as synaptically released zinc, are also considered neurotransmitters by some, as are a few gaseous molecules such as nitric oxide (NO) and carbon monoxide (CO). These are not neurotransmitters by the strict definition, however,
