Carbohydrates are examples of food types or biomolecule utilised by living organisms to acquire energy amon other functions. They are classified into monosaccharides, disaccharides and polysaccharides. Polysacchrides conatin multiple monosaccharides joined together by bonds forming a long chain and a complex molecule, for example, chitin, cellulose and peptidoglycan. These polysaccharides exists as a set of long, parallel strand that are linked to one another, a feature that makes them act a structural molecules withstanding pulling and pushing forces well.
1. The glutamate causes an influx of ca2+ ions into the nerve cell akin to what occurs during depolarization. However, this occurs excessively without regulation (due to excessive stimulation by the glutamate) that eventually causes nerve injury through cytotoxic edema.
2. When the ca2+ levels are lowered during stroke, then nerve cell injury would be obviated hence enabling the chances of restoration of nerve cell function. This would happen because there would be no excess calcium ions to influx when the NMDA receptors are excessively stimulated by the glutamate molecules.
Chlorophyll is the source of carbon in the sugar molecule
