What is Krebs cycle?

The Krebs cycle is a cycle that is after glycolysis which allows the cell to get more ATP and have more ATP efficiency than that of glycolysis itself or fermentation and glycolysis. Infact, it makes the ATP effeciency about 20 times of glycolysis itself! Here is the Krebs cycle: Step 1: The acetyl CoA (a two carbon) joins with oxaloacetic acid (a four carbon). The CoA (Coenzyme A) is returned back to the mitochondira. The result is a six carbon called citric acid. Step 2: The citric acid gives off carbon dioxide and gives a hydrogen ion (H+) to NAD+ resulting in NADH. Since the citric acid gave off a carbon in the form of CO2, (carbon dioxide) it is now a 5-carbon molecule. Step 3: The 5-carbon molecule then gives off CO2 once again, gives a hydrogen ion(H+) to NAD+ resulting in NADH, and in this process, phosphate joins with ADP to create ATP. The resulting molecule is a 4-carbon. Step 4: The 4-carbon molecule gives a hydrogen ion (H+) to FAD (similar to NAD), which results to FADH2. Step 5: The 4-carbon molecule once again gives off H+ to NAD resulting into NADH. The 4-carbon molecule is then known as oxaloacetic acid, and the cycle begins again. Remember:glycolysis produces 2 pyruvic acid molecules, which produces 2 acetyl CoA molecules (and 2 NADH), which means that for every molecule of glucose, the Krebs cycle happens twice. The resulting amounts of NADH and FADH2 go through the electron transport chain and the enzyme ATP synthase to produce a waste of water, ATP molecules, and a restoration of the NADH to NAD+ and the FADH2 to FAD+ so that they can be used again in the Krebs cycle.


What causes an exothermic reaction with alka seltzer?

Alka-Seltzer contains aspirin, sodium bicarbonate (baking soda) and citric acid. When placed in water, the tablet dissolves. The citric acid reacts with the baking soda, and gives off carbon dioxide, which makes bubbles in the water. If you have heartburn, that is caused by too much stomach acid. The baking soda in an Alka-Seltzer counteracts the stomach acid.


What process occurs after glycolysis?

aerobic oxidatio of pyruvic acid after pyruvic acid is form it get transfer to mitochondria. as soon as pyruvic acid enter to mitochondria it get oxidise to c02 in the reaction called oxidative decarboxylation. here 1st it get decarboxylate and then it get oxidised by the help of enzyme called pyruvate dehydrogenase. nd this enzym is made up of decarboxylase,lipoic acid amid tpp [thiamine pyrophosphate] nd in the presence of some cofactor such as vit b1 nd mg ions. reaction given below pyruvate + NAD+ + co-A = acetyl co-A + NADH + H+ + c02


What are the steps occur when preparing pyruvic acid to enter the citric acid cycle?

1st step is when C2 CoA enters the inner matrix of mitochondrion. So given, C2 + C4 (oxalo-acetic acid) = C6 is also called Citric acid which may came from fruits, then the "lower form" of citric acid is called Isocitric acid(2nd step) but it is still C6 form the 3rd step is when there is a prescence of NAD and that NAD have hydrogen which gives off electron , that made Co2 go out, and because of that you need to subtract everything that goes out , and since carbon is just 1 the equation would be C6(isocitric) minus C1(carbon) = C5 which is called alpha-ketoglutaric acid, then the same process is done again in which there is again a prescence of NAD and that NAD have hydrogen which gives off electron , that made Co2 go out, and because of that you need to subtract again everything that goes out , and since carbon is just 1 the equation would be C5(a-ketoglutaric) minus C1 (carbon) = C4 which is also called Succinic acid. the other four succinic acid are , Fumaric then malic then oxalo-acetic acid , then there is an excess hydrogen again that would be use for mixture of acetyl co enzyme or C2 CoA which is what we did in the first step. Why? In Krebs cycle,. this process is repeated two times.

Where does citric acid come from?

How is citric acid produced? Good question! citric acid is produced in a cycle called Krebs Cycle. As Pyruvic acid enters the mitochondrion, carbon is removed,forming co2, and electrons are removed, changing NAD+ to NADH. Co-enzyme A joins the 2-carbon molecule, forming acetyl-CoA. Acetyl-CoA then adds the 2 carbon acetyl group to a 4-carbon compound, forming citric acid. Before the Krebs cycle there is the glycolysis cycle. In this cycle the product is the pyruvic acid. So after that the Krebs cycle or the Citric acid cycle starts, which starts off with pyruvic acid. Then the election transport cycle. This might be confusing but if you see a diagram of these cycles, that will help you a lot! hi my name is austin im looking for more firends so if you see this add me on facebook @ sexyzigrat@hotmail.com :)

Can citric acid be separated from water?

Yes - evaporate the water off with heat.


Do taking citric acid with hot water cut down belly fats?

Hi, As per my understanding the citric acid when taken cuts off the FAT. Lemon is the most convinient source of Citric Acid. Thats it is advised to have a glass of lemon water first thing in the morning.


Does Hydrochloric acid kill citric acid in your stomach?

First off. You should NOT be drinking hydrochloric acid. Second, hydrochloric acid added to another acid is just that, more acid.

Can you mix sodium bicarbonate and citric acid together to use instead of sodium carbonate in homemade laundry?

first you should take an beaker and then put 1 tea spoon of sodium bi carbonate and another tea spoon of citric acid as you put them the citric acid will give out bubbles and it will go off and when you touch the vessel the vessel is cold.

When NADH loses a hydrogen ion?

It becomes NAD. This happens during electron transport where NADH drops off its H+ and electrons to be used in oxidative phosphorylation. NAD now must move to glycolysis or citric acid cycle to regain its hydrogen.


What is the saturation rate of citric acid in water?

By chelating the metals in hard water, it lets these cleaners produce foam and work better without need for water softening. In a similar manner, citric acid is used to regenerate the ion exchange materials used in water softeners by stripping off the accumulated metal ions as citrate complexes.The saturation point for citric acid and water is 59%.


How often is power turned off during a cycle of ac voltage?

Twice.
