How does NAD+ become NADH? Why does this electron transfer (NAD+ to NADH) occur? How does chemiosmosis relate to oxidative phosphorylation? Explain glycolysis and how glucose is broken down into two molecules of pyruvate. How much NADH is produced during oxidative metabolism? What can reduce the...
How does NAD+ (NADH) function in cellular respiration? How has the mitochondria adapted to its respiration function What is the difference between anaerobic and aerobic respiration? What is aerobic and anaerobic respiration? What is the difference between aerobic and anaerobic respiration? How is gluc...
How does NADH get into the mitochondria? Electrons from NADH can enter the mitochondrial electron transport chainby being used to reduce dihydroxyacetone phosphate to glycerol 3-phosphate. ... The use of FAD enables electrons from cytosolic NADH to be transported into mitochondria against an NADH co...
From this point, G3P is phosphorylated in a step that also produces NADH from the oxidized form NAD+, and then the two phosphate groups are given up to ADP molecules in subsequent rearrangement steps to produce two ATP molecules along with the end carbon product of glycolysis, pyruvate. Sinc...
Hence, rising levels of NADH/NAD+ is a major factor leading to increased mitochondrial ROS production (Murphy, 2009). When breakdown of metabolites in the TCA cycle exceeds the capacity of the ETC to assimilate the resulting electrons, ROS production increases. In addition, stalling of the ETC...
GAPDH converts glyceraldehyde-3-phosphate (G3P) and NAD+ into 1,3-bisphosphoglycerate (1,3-BPG) and NADH. It also plays an important role in aerobic glycolysis and has been found to be upregulated in the contexts of several kinds of cancer, but the exact cause of the upregulation remai...
NADH and FADH2 carry electrons to specialized cell membranes, where they are harvested to create ATP. Once the electrons are used, they become depleted and must be removed from the body. Oxygen is essential for this task. Used electrons bind with oxygen; these molecules eventually bind with hyd...
If the cell had no backup plan to regenerate NAD+, glycolysis would also cease, and the cell would rapidly die. The method of removing the electron from NADH in the absence of oxygen is to pass the electron to pyruvate, the end product of glycolysis, to form lactic acid. This method ...
How does ATP result from the oxidation of glucose? Where are they produced? What are the structural and functional differences between NADH and NADPH? Which of the following are produced when Hydrogen ions diffuse from the lumen of the Thylakoid to the Stoma? a) ATP b) NADPH c) Carbon Diox...
C. It does not use the electron transport chain to convert NADH to NAD^+ How is the fermentation different from cellular respiration? A. It skips glycolysis, thereby missing out on the ATP generated by ATP synthase. B. It does not use pyruvate as a substrate. C....
