How is hydrogen carried from Krebs cycle to the cytochrome system?
The hydrogen from Krebs cycle to the cytochrome system is carried through NADH2 molecules.
What is the waste product of cellular respritiaon?
carbon dioxide and metabolic water are waste products of cellular respiration. carbon dioxide is formed in the citric acid or Krebs cycle. metabolic water is formed when hydrogen ions are attached to the final electron acceptor oxygen. hydrogen ions are attracted to oxygen because it has a very high electronegativity.
Can the kreb's cylce occur if there is no oxygen?
No, the Krebs cycle requires oxygen as the final electron acceptor in the electron transport chain to function properly. Without oxygen, the electron transport chain cannot proceed, leading to a buildup of molecules that inhibit the Krebs cycle. This can result in the Krebs cycle slowing down or ceasing altogether.
What two hydrogen carrying molecules are formed during the Krebs cycle?
The two high energy molecules that are produced in the Krebs Cycles are NADH and FADH2. :D
What happens to pyruvate if electron acceptor is absent and What happens if electron acceptor is present?
If an electron acceptor is absent, pyruvate undergoes fermentation, resulting in the production of lactate in animals or ethanol and carbon dioxide in yeast, allowing for the regeneration of NAD+ and enabling glycolysis to continue. In contrast, if an electron acceptor is present, pyruvate enters the mitochondria and is oxidized in the citric acid cycle (Krebs cycle), leading to the production of ATP, NADH, and FADH2 through aerobic respiration. This process is more efficient in energy production compared to fermentation.

What does nad and nadh do in the Krebs cycle?
Well for people who aren't familiar with the abbr. Nicotinamide adenine dinucleotide aka NAD acts as an electron and hydrogen carriers in some oxidation-reduction reactions in the Krebs Cycle, and flavin adenine dinucleotide aka FAD is a hydrogen acceptor molecule in the Krebs Cycle.

What is the intermediate electron acceptor for oxidations that occur in both glycolysis and in Krebs cycle reactions?
The intermediate electron acceptor for oxidations in both glycolysis and the Krebs cycle is NAD+ (nicotinamide adenine dinucleotide). NAD+ accepts electrons and becomes reduced to NADH during these metabolic pathways. NADH can then donate its electrons to the electron transport chain for further energy production.

What two substances carry hydrogen from the Krebs Cycle to the electron transport system?
FADH and NADH.

What is FADPH?
There is a typo in your question. The correct term is NADPH, which stands for Nicotinamide Adenine Dinucleotide Phosphate. NADPH is a coenzyme that plays a key role in various redox reactions in cells, including the synthesis of biomolecules and the neutralization of reactive oxygen species.
What happend to hydrogen ions during Krebs cycle?
During the Krebs cycle, hydrogen ions (H⁺) are generated as a result of the oxidation of acetyl-CoA and other intermediates. These hydrogen ions are transferred to electron carriers, specifically NAD⁺ and FAD, which are reduced to NADH and FADH₂. This transfer of electrons, along with the accompanying hydrogen ions, is crucial for the subsequent production of ATP in the electron transport chain, where the energy from these electrons is harnessed to create a proton gradient.
During cell respiration what is the purpose of NAD and FAD?
FADS and NADS Pick up, temporarily store and safely eat out while the mitochondria energy does electronsconnect to onlit the electron transport chain.I didn't want to change someone's answer, but according to biology-online.org,Both are enzymes; NAD acts as an electron and hydrogen carriers in some oxidation-reduction reactions. FAD is a hydrogen acceptor molecule in the Krebs Cycle.See below:Nicotinamide adenine dinucleotide --> nad(Science: enzyme) coenzymes that act as electron and hydrogen carriers in some oxidation-reduction reactions.Fad(Science: biochemistry) a riboflavin-containing hydrogen Acceptor molecule in the Krebs Cycle of plant respiration and a coenzyme of some oxidation-reduction enzymes.
How many molecules of CO2 are released during the Krebs cycle?
For every molecule of pyruvate entering the Krebs cycle, 3 molecules of CO2 are released. Since each glucose molecule produces 2 molecules of pyruvate through glycolysis, the total number of CO2 molecules released per glucose molecule in the Krebs cycle is 6.
