The Krebs cycle, also known as the citric acid cycle or tricarboxylic acid cycle, is part of a series of chemical reactions that organisms use to break down food into a form of energy that cells can use. The cycle occurs in themitochondriaof cells, using 2 molecules of pyruvic acid fromg...
What role do NADH and FADH2 play in the process of cellular respiration? Explain how losing an electron makes a molecule have a greater charge, like when NAD+ is converted to NADH+ H+. Why does pyruvate require active transport? Why is there no oxygen involved in the Krebs cycle?
The Krebs cycle, sometimes called the tricarboxylic acid (TCA) cycle or the citric acid cycle, is a sequence of chemical processes that take place in the mitochondria of eukaryotic cells. It plays a critical role in cellular respiration by oxidizing acetyl-CoA, releasing energy that is used to...
The Krebs Cycle (also known as the Citric Acid Cycle): This is the main driver of cellular respiration or energy creation. It takes the oxidized form of pyruvate (from glycolysis described above) and through a series of redox reactions, and another process called the electron transport chain,...
» The Krebs Cycle begins with pyruvate, and as we have two molecules of pyruvate here, the net ATP gain there will also be multiplied by 2. After glucose is converted to pyruvate:- » If air is absent –Anaerobic Glycolysis NADH (produced at reaction V) reduces pyruvate to lactate. ...
Bicarbonate is a simple single carbon molecule that plays surprisingly important roles in diverse biological processes. Among these are photosynthesis, the Krebs cycle, whole-body and cellular pH regulation, and volume regulation. Since bicarbonate is charged it is not permeable to lipid bilayers. ...
This process, called lipolysis, takes place in the cytoplasm. The resulting fatty acids are oxidized by β-oxidation into acetyl CoA, which is used by the Krebs cycle ...Is glyceryl trioleate a triacylglycerol?Glyceryl trioleate is derived from glycerol. It is composed of three oleic acid ...
Furthermore, a similar thiamine-dependent enzyme complex positioned at the interface between glycolysis and the Krebs cycle called the pyruvate dehydrogenase complex (PDHC) also requires magnesium, but indirectly. The PDHC is essential for carbohydrate metabolism. Although magnesium ions do not directly ...
Toxins accumulate in the tissues which depletes oxygen availability whereby the Krebs cycle shifts away from burning mainly fats to mainly sugars. Massive lactic acid production results which, when combined with sodium, precipitates as salts into the tissues driving up the pH into hyperalkalinity. ...
Explain respiration, glycolysis of the Krebs cycle Before the citric acid cycle can begin, pyruvate loses CO2 to form acetyl-CoA, a two-carbon molecule. During the citric acid cycle, acetyl-CoA is oxidized to form CO2, and this process...
