What is the sequence of electron carriers in the electron transport chain starting with the least electronegative?
The sequence of electron carriers in the electron transport chain starting with the least electronegative includes NADH dehydrogenase, ubiquinone, cytochrome b-c1 complex, cytochrome c, and cytochrome oxidase. These carriers are responsible for transferring electrons, creating a proton gradient, and ultimately generating ATP through oxidative phosphorylation.
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 can one buy from the store Cytochrome?
One can buy cytochrome c, a highly conserved model protein for molecular evolution. After supplied, the cytochrome c product stays stable for five years.
What is cytochrome P-450 used for?
The family of liver isoenzymes known as cytochrome P-450 are crucial to drug metabolism
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.
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 role of the cytochrome complex in photosynthesis?
Cytochrome BF is a complex that is involved in the electron and H+ transportation in chloroplast. During the light dependent reaction in the chloroplast, cytochrome BF uses high energy electrons from the PSi PSii proteins to transport H+ across the Thylakoid membrane to be used later to synthesize ATP. Cytochrome BF is homologous to Cytochrome BC in Mitochondria, which is used in the electron transport chain in cell respiration.
Is cytochrome a coenzyme?
Cytochrome is not a coenzyme, but rather a type of heme-containing protein that plays a critical role in electron transport in cells. It acts as a carrier of electrons in the respiratory chain.
What is the colour of cytochrome c?
Cytochrome c is a protein that is typically described as brown or brownish-red in color.
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.
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
What organism whose cytochrome c is most like human cytochrome c?
The great apes (such as chimpanzees and gorillas) have cytochrome c sequences that are most similar to human cytochrome c. They share a common ancestor with humans relatively recently in evolutionary terms, resulting in a high degree of sequence similarity.
