What are the reactants of Krebs cycle?
The reactants of the Krebs cycle are acetyl CoA, oxaloacetate, and water. This series of reactions occurs in the mitochondria and involves the oxidation of acetyl CoA to produce ATP and reduced coenzymes.
Is CoA an electron carrier?
No, CoA (Coenzyme A) is not an electron carrier. It primarily functions as a carrier of acyl groups in various metabolic pathways, facilitating the transfer of acyl groups during fatty acid metabolism. NADH and FADH2 are examples of electron carriers.
What molecules are the main electron carriers in the Krebs cycle?
The main electron carriers in the Krebs cycle are NAD+ (nicotinamide adenine dinucleotide) and FAD (flavin adenine dinucleotide). During the cycle, NAD+ is reduced to NADH, and FAD is reduced to FADH2, both of which then transport electrons to the electron transport chain. These carriers play a crucial role in facilitating the conversion of the energy stored in acetyl-CoA into usable ATP through oxidative phosphorylation.
What is the outcome of the Krebs cycle?
Products of one cycle:2 CO23 NADH1 GTP (or ATP in bacteria)1 FADH2Acetyl-CoA (6 carbon) enters the cycle, and is converted into 2, 3 carbon molecules.
Where is FAD in the mitochondria?
FAD (flavin adenine dinucleotide) is not located in the mitochondria, but rather it is a coenzyme that functions in the electron transport chain within the inner mitochondrial membrane. FAD participates in redox reactions to help generate ATP through oxidative phosphorylation.
What are two examples of coenzymes used in cellular respiration?
Two examples of coenzymes used in cellular respiration are NAD+ (nicotinamide adenine dinucleotide) and FAD (flavin adenine dinucleotide). These coenzymes accept and carry electrons during the process of respiration, allowing for the production of ATP.
What are the inputs and outputs of the citric acid cycle?
The net inputs for citric acid cycle are Acetyl CoA, NADH, and ADP. The Net outputs for the citric acid cycle are ATP, NAD, and carbon dioxide.
What are the reactants of Krebs cycle?
The reactants of the Krebs cycle are acetyl CoA, oxaloacetate, and water. This series of reactions occurs in the mitochondria and involves the oxidation of acetyl CoA to produce ATP and reduced coenzymes.
Is CoA an electron carrier?
No, CoA (Coenzyme A) is not an electron carrier. It primarily functions as a carrier of acyl groups in various metabolic pathways, facilitating the transfer of acyl groups during fatty acid metabolism. NADH and FADH2 are examples of electron carriers.
For each acetyl-CoA that enters the citric acid cycle what leaves the cycle?
The citric acid cycle turns 3 NAD+ to NADH, one FAD to FADH2 one ADP + P to ATP, and it also creates two CO2 molecules.
What coenzymes are required for beta oxidation?
Coenzyme A (CoA) and flavin adenine dinucleotide (FAD) are required coenzymes for beta oxidation. CoA helps in the transfer of acyl groups during fatty acid breakdown, while FAD is involved in the electron transfer reactions during the process.
Nucleotides are the building blocks for?
ATP, NAD+ , and FAD Pg 46
WHat are the Krebs cycle reactants?
This cycle occurs only in the presence of oxygen. It takes place in the mitochondria.The oxidation of pyruvic acid into CO2 and water is called Krebs cycle:Pyruvic acid +CoA --------> Acetyl CoA +CO2. This reaction is catalyzed by a set of enzymes called pyruvic acid dehydrogenase. In this reaction, 2 hydrogen atoms and one CO2 molecule are removed.The 2 hydrogen atoms are accepted by NAD and NAD is converted into NADH.Pyruvic acid and CoA are the reactants. The products are 2 H+ and CO2 and Acetyl CoA.
How does many ATP produced from 2 moles of pyruvate in Krebs cycle?
For each mole of pyruvate, the Krebs cycle produces 3 molecules of NADH, 1 molecule of FADH2, and 1 molecule of ATP. Therefore, from 2 moles of pyruvate, the Krebs cycle produces 6 molecules of NADH, 2 molecules of FADH2, and 2 molecules of ATP. These NADH and FADH2 molecules go on to generate more ATP through oxidative phosphorylation in the electron transport chain.
What is the outcome of the Krebs cycle?
Products of one cycle:2 CO23 NADH1 GTP (or ATP in bacteria)1 FADH2Acetyl-CoA (6 carbon) enters the cycle, and is converted into 2, 3 carbon molecules.
Where is FAD in the mitochondria?
FAD (flavin adenine dinucleotide) is not located in the mitochondria, but rather it is a coenzyme that functions in the electron transport chain within the inner mitochondrial membrane. FAD participates in redox reactions to help generate ATP through oxidative phosphorylation.
Where are the products and reactants of the Krebs Cycle and where does it take place?
The products of the Krebs Cycle are ATP, NADH, FADH2, and carbon dioxide. The reactants are acetyl-CoA, NAD+, FAD, and ADP. The Krebs Cycle takes place in the mitochondrial matrix of eukaryotic cells.
