Type your answer here... Cytochrome C Oxidase deficiency is a very rare inherited metabolic disorder characterized by deficiency of the enzyme cytochrome C oxidase (COX), or Complex IV, an essential enzyme that is active in the subcellular structures that help to regulate energy production (mitochondria).

Are all aerobic bacteria oxidase positive?
yes, all aerobic cells are oxidase positive. The oxidase test is testing for the presence of cytochrome oxidase [by reducing it with an artificial substrate which turns purple when oxidised]. In aerobic cells cytochrome oxidase's normal role is in the electron transport chain, passing electrons from cytochrome c to oxygen. hence if the cell is aerobic then oxygen is terminal electron acceptor in the cells ETC and thus it will give a positive result in the oxidase test.
Why is It advisable to include an oxidase positive control organism in any test of an unknown organism?
It's advisable so that the oxidase test determines whether or not an organism has cytochrome oxidase in its electron transport chain.
Why are strict aerobes oxidase positive?
Strict aerobes must be oxidase positive because oxidase is an enzyme. It is critical to cellular respiration, specifically the final reduction of oxygen in the electron transport chain.
Give a reason why cyanide effects the cellular respiration process if it enter the cell?
Cyanide deactivates the enzyme cytochrome c oxidase. This is the last enzyme of the electron transport chain (the final step of cell respiration). The electron transport chain allows a great concentration of protons (H+ ions) to build up in the matrix of mitochondria so that they can diffuse back through a channel which in turn synthesises ATP. So basically cyanide stops the last step of cell respiration from occurring and as such inhibits ATP synthesis.
How do you distinguish between micrococcus roseus and staphylococcus?
staphylococcus are Gram negative cocci, and division in them occur in multiple axes which result in the formation of grape-like cluster when observed under light microscope but streptococcus divide in single axis only therefore produce a chain of bacteria
Give explanation why the Oxidase test identifies the presence of cytochrome c oxidase and not the other electron carriers?
An oxidase test relies on a reagent that will change colors when it is oxidized. The reagent used in the test only reacts to cytochrome c oxidase by acting in place of oxygen to receive electrons from the cytochrome.

What is the function of Oxidases?
cytochrome oxidase catalyzes the oxidation of a reduces cytochrome by molecular oxygen, resulting in the formation of H2O or H2O2.
What is the function of the cytochroms?
cytochrome oxidase catalyzes the oxidation of a reduces cytochrome by molecular oxygen, resulting in the formation of H2O or H2O2.
Where are you likely to find the enzyme cytochrome oxidases?
Cytochrome Oxidase are most likely to be found in mitochondria and important in cell respiration as an agent of electron transfer from certain cytochrome molecules to oxygen molecules
How the person will die after taking cyanide?
cytochrome oxidase enzyme system is knoched out in mitochondria.
Why is it advisable to include an oxidase-positive control organism in any test of an unknown organism?
It's advisable so that the oxidase test determines whether or not an organism has cytochrome oxidase in its electron transport chain.
Why is it advisable to include a known oxidase-positive control in any test of an unknown organism?
It's advisable so that the oxidase test determines whether or not an organism has cytochrome oxidase in its electron transport chain.
Why is It advisable to include an oxidase positive control organism in any test of an unknown organism?
It's advisable so that the oxidase test determines whether or not an organism has cytochrome oxidase in its electron transport chain.
What is the sequence of electron carriers in the electron transport chain starting with the least electronegative?
NADH Dehydrogenase Ubiquinone Cytochrome b-c1 complex Cytochrome c Cytochrome oxidase complex
What has the author J C Horton written?
J. C. Horton has written: 'Cytochrome oxidase patches'
What is the disease caused by a deficiency of Homogentisate oxidase?
Alkaptonuria
