What else can I help you with?
Do bacteria contain cytochrome C?
Yes, some bacteria do contain cytochrome C. Cytochrome C is a heme-containing protein involved in electron transport in the mitochondria of eukaryotic cells and in some bacteria as well. It plays a key role in cellular respiration by transferring electrons between complexes in the electron transport chain.
What is an important mineral ion of the cytochrome pigments of cellular respiration?
An important mineral ion of the cytochrome pigments of cellular respiration is Iron. An important mineral ion that is a component of chloroplasts and stabilizer of membranes and ribosomes is Magnesium .

Is cytochrome c a protein molecule?
Yes. It is a highly soluble protein associated with the 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.
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.
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.
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.
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
Do bacteria contain cytochrome C?
Yes, some bacteria do contain cytochrome C. Cytochrome C is a heme-containing protein involved in electron transport in the mitochondria of eukaryotic cells and in some bacteria as well. It plays a key role in cellular respiration by transferring electrons between complexes in the electron transport chain.
What stages of cellular respiration involve cytochromes?
Cytochromes are involved in electron transport chain, specifically in the complexes III and IV stages of cellular respiration. In complex III, cytochrome b and cytochrome c are key components, while in complex IV, cytochrome c oxidase plays a crucial role in the final transfer of electrons to oxygen.
How many cytochrome c do humans have?
Humans have only one cytochrome c gene, which encodes a single protein that is essential for the electron transport chain in mitochondria. This protein plays a crucial role in cellular respiration by transferring electrons between complexes in the chain.
What has the author Vaishali S Shenoy written?
Vaishali S. Shenoy has written: 'Contribution of protein environment to redox potentials of rubredoxin and cytochrome c' -- subject(s): Physiological transport, Proteins, Cytochrome
What are the carrier proteins in the electron transport chain?
The carrier proteins in the electron transport chain include NADH dehydrogenase (Complex I), cytochrome b-c1 complex (Complex III), cytochrome c, cytochrome oxidase (Complex IV), and ubiquinone (coenzyme Q). These proteins facilitate the transfer of electrons from NADH and FADH2 to ultimately generate ATP through oxidative phosphorylation.
What is an important mineral ion of the cytochrome pigments of cellular respiration?
An important mineral ion of the cytochrome pigments of cellular respiration is Iron. An important mineral ion that is a component of chloroplasts and stabilizer of membranes and ribosomes is Magnesium .
What are cytochrome carriers?
they are part of the electron transport chain and they are involved with the pumps that create the concentration gradient of H+
Is there molecular evidence for evolution?
Take the cytochrome C electron shuttle in the electron transport chain and see how it is highly conserved in form and function among a wide variety of eukaryotes. That is molecular evidence for the relatedness of widely disparate organisms.
