3-hydroxy-3-methyl-glutaryl-CoA reductase (HMG-CoA reductase) is a very long name for the enzyme that is involved in the production of cholesterol in the human liver. The enzyme catalyzes a reaction in which electrons are exchanged between reactants to form products. This an example of which of the following chemical reactions that are involved in maintaining homeostasis? HMG-CoA reductase catalyzes a catabolic reaction because electrons are exchanged between the reactants to form products. HMG-CoA reductase catalyzes a specific type of exchange reaction called an oxidation-reduction reaction in which electrons are exchanged between reactants to form products. HMG-CoA reductase catalyzes an anabolic reaction because electrons are exchanged between the reactants to form products. HMG-CoA reductase catalyzes a specific type of oxidation-reduction reaction called an exchange reaction in which atoms are exchanged between reactants to form products.
Electron Transport Chain
The electron transport chain, also known as the electron transport system, is a group of proteins that transfer electrons through a membrane within mitochondria to create a gradient of protons that drives adenosine triphosphate (ATP)synthesis. The cell uses ATP as an energy source for metabolic processes and cellular functions. ETC involves series of reactions that convert redox energy from NADH (nicotinamide adenine dinucleotide (NAD) + hydrogen (H)) and FADH2(flavin adenine dinucleotide (FAD)) oxidation into proton-motive force(PMF), which is then used to synthesize ATP through conformational changes in the ATP synthase complex, a process known as oxidative phosphorylation.
Metabolism
Picture a campfire. It keeps the body warm on a cold night and provides light. To ensure that the fire keeps burning, fuel needs to be added(pieces of wood in this case). When a small piece is added, the fire burns bright for a bit and then dies down unless more wood is added. But, if too many pieces are placed at a time, the fire escalates and burns for a longer time, without actually burning away all the pieces that have been added. Many of them, especially the larger chunks or damp pieces, remain unburnt.
Cellular Respiration
Cellular respiration is the cellular process involved in the generation of adenosine triphosphate (ATP) molecules from the organic nutritional source obtained from the diet. It is a universal process observed in all types of life forms. The glucose (chemical formula C6H12O6) molecules are the preferred raw material for cell respiration as it possesses a simple structure and is highly efficient in nature.

oxidation-reduction reaction in which electrons are exchanged between reactants to form products. - HMG-CoA reductase catalyzes an anabolic reaction because electrons are exchanged between the reactants to form products.
- HMG-CoA reductase catalyzes a specific type of oxidation-reduction reaction called an exchange reaction in which atoms are exchanged between reactants to form products.
- Like most enzymes, HMG-CoA reductase is a protein that acts as a catalyst. The statin medication prescribed to Kevin binds to the active site of this enzyme, which blocks the production of cholesterol in his liver.
- What are the properties associated with enzymes? Statin medications are very similar in chemical structure to the normal substrate for the HMG-CoA reductase enzyme.
- Which of the properties associated with enzymes allows for similar chemical compounds to bind an enzyme’s active site?
