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.
Cytochrome c is a protein found in the electron transport chain of all eukaryotes. The table below shows the relative differences in cytochrome c among several species. What conclusion can you draw fr?
The relative differences in cytochrome c among various species suggest evolutionary relationships and divergence among those species. More closely related species tend to have more similar cytochrome c sequences, indicating a common ancestry. Conversely, significant differences in the cytochrome c protein sequences may point to a longer evolutionary distance and divergence from a common ancestor. This information can be useful for phylogenetic studies and understanding evolutionary processes.
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.
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.
How does cyanide and DNP work on cellular respiration?
Cyanide blocks the last step in the production of ATP. The binding of cyanide to cytochrome c oxidase prevents transport of electrons from cytochrome c to oxygen. No ATP will be produced. The central nervous system and the heart are the most to be affected. Death can occur in minutes.
What is the colour of cytochrome c?
Cytochrome c is a protein that is typically described as brown or brownish-red in color.
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 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.
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 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.

What part of cellular respiration in most likely to be inhibited by cyanide?
Cyanide blocks cytochrome c oxidase in the mitochondria. This is a transmembrane protein that establishes a proton gradient used by ATP synthase to create ATP. This shuts down ATP production leading to a quick death if exposure is high enough.
What has the author J C Horton written?
J. C. Horton has written: 'Cytochrome oxidase patches'
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.
Which animal woudl you expect to have cytochrome c more similar to that of dog?
•Crickets and dogs aren't really related at all. So it stands to reason that the cytochrome c of a cat would be more similar to that of the dog.
