How many NADH's are generated after one cycle of the TCA?
6 NADH
What does NADPH add to the Calvin cycle?
NADH is generated by the electrons transferred to the NAD+. It is used in oxidative phosphorylation of for ATP synthesis later on.
How many NADH are produced during fermentation?
The fermentation pathway itself does not generate NADH itself. In fact NAD+ builds up. Glycolysis uses the NADH when oxidating carbon substrates and fermentation is used to regenerate the NAD+ and thus the cycle continues. If fermentation did not exist, NADH would build up and the cell would not be able to oxidize carbon anymore. The cell would die. In the case of respiration (aerobic or anaerobic) the cell will replenish its NAD+ pool the electron transport chain (oxidative phosphorylation). This generates even more potential to make ATP by pumping protons out of the cell using the energy generated from NADH -> NAD via NADH dehydrogenase. This gradient can be utilized by allowing the protons to flow back into the cell through ATPase, generating ATP. The utilization of NADH to pump protons out of the cell is the sole reason why respiration generates 36-38 ATP while fermentation generates 2 ATP per glucose. After much rambling, the point to take home is that the main job of fermentation in the cell is the replenish the NAD+ pool so that glycolysis can continue which drives biosynthesis.
Most energy that enters electron transport enters as?
FADH2 and NADH
What is the most simple nervous system pathway?
The reflex arc is the simplest neural circuit.
How many NADH's are generated after one cycle of the TCA?
6 NADH
What is the Fullform of NADH?
From my basic Biochemistry knowledge NADH stands for Nicotinamide Adenine Dinucleotide, a reduced form of pyridine dinucleotide and is a principle electron donor in the respiratory chain pathway in mamalian cells.
What is generated by the Kreb cycle?
FADH2 and NADHIt gives four products.They are ATP,CO@, FADH2 and NADH
What products are made by glycolysis?
In Glycolysis the Glucose under goes several process and finally they obtain pyruvate. We have 4 ATP and 2 NADH in this pathway. The pathway was given below.
How many ATP are generated in aerobic phase of respiration?
It depends wether or not NADH from glycolisis enters or not. If yes, then 38. If not, then 36 come from the electron transport chains and other ATP.
What does NADPH add to the Calvin cycle?
NADH is generated by the electrons transferred to the NAD+. It is used in oxidative phosphorylation of for ATP synthesis later on.
At the end of the citric acid cycle most of the energy remaining from the original glucose is stored in where?
As reducing agents NADH and FADH2, with NADH holding the majority
Describe a pathway used for degradation of carbohydrates?
This is called the glycolysis pathway. It begins with glucose and ends with pyruvate before entering the Krebs cycle where ATP (adenosine triphosphate) is generated for energy.
What happens to high energy electrons generated during Krebs cycle?
The cells do with all those high-energy electrons in carriers like NADH? in the presence of oxygen, those electrons can be used to generated huge amounts of ATP.
What energy carrier is produced during glycolysis?
There are a few energy carrier produced during Glycolysis but NADH and ATP are most produced.
How does ethanol inhibit glycolysis?
Ethanol (CH3-CH2-OH) is metabolized into an aldehyde (CH3-CHO) via the enzyme alcohol dehydrogenase(ADH). Written out, it looks like this : CH3CH2OH + NAD+ → CH3CHO + NADH + H+ The ADH reaction generates NADH/H+ as one of the products. NADH/H+ is also one of the products of glycolysis (in the glyceraldehyde 3-phosphate dehydrogenase reaction). NADH/H+, being one of the products in glycolysis, also acts as an inhibitor for glycolysis, which is a way of self-regulation for the metabolic pathway.
