The type of the reaction, name and the class of enzyme involved in each step of citric acid cycle should be identified. Concept Introduction: Citric Acid Cycle: It involves 8 series reaction which converts acetyl group present in acetyl coenzyme A into 2 C O 2 molecules. Enzyme: The proteins that helps chemical reaction to occur. The enzymes are classified as follows, Oxidoreductases Transferases Hydrolases Isomerases Lyases Ligases Oxidoreductases are one of the main classifications of enzymes and it catalyzes the oxidation-reduction reactions and it can be divided into three subclasses which are Oxidases, Reductases and Dehydrogenases. Ligases are one of the main classifications of enzymes and it catalyzes the bonding of two substrate molecules and it can be divided into two subclasses which are Synthetases, and Carboxylases. Isomerases are one of the main classifications of enzymes and it catalyzes the reaction in which the rearrangement of atoms in a substrate occurs. Lyases are one of the main classifications of enzymes and it catalyze the addition or elimination of a functional group without hydrolysis from a substrate and it can be divided into subclasses which are Decarboxylases, Deaminases, Dehydratases and Hydratases. Condensation Reaction: It involves combination of two small molecules to form larger molecule with elimination of small molecule. Rearrangement Reaction: It involves change in the carbon chain of the molecule that results to give structural isomer. Oxidative Decarboxylation: It involves removal of carboxylate group that results in release of carbon dioxide. Phosphorylation: It involves transfer of phosphate group from inorganic/organic phosphate to another chemical compound. Oxidation: The oxidation is reaction that involves addition of oxygen atom or loss of electrons or removal of hydrogen atom present in the chemical compound. Hydration: The combination of substance with water is termed as hydration.

When sodium ions enter a neuron during depolarization, they trigger the opening of additional voltage-gated sodium channels nearby, creating a positive feedback loop where the influx of sodium ions further depolarizes the membrane, causing even more sodium channels to open and allowing more sodium ions to enter the cell, thus sustaining the depolarization process until the action potential peaks. But how and why exactly does the influx of sodium ions trigger more sodium channels to let in more sodium? Please explain
