Answer:
The correct answer is D. The cytochromes
Explanation:
Cytochromes are proteins which contain tightly bound heme metal which easily undergoes oxidation and reduction and are responsible for accepting and donating the electron. They play an important role in the electron transport chain and helps in formation of ATP during oxidative phosphorylation.
The metal ion provides the capability to the cytochrome to gain and loss the electron. a, b, and c are the three classes of cytochrome out of which cytochrome c is the most abundant and stable.
Therefore the redox carrier of ETC that have bounded metal atom are cytochromes.
Answer:
false
Explanation:
the nucleus contains neutrons, but electrons and protons orbit the nucleus.
Answer:
List three protozoan infections of the circulatory system that are transmitted by arthropods:
Malaria
Toxoplasmosis
Chagas disease (American trypanosomiasis)
Explanation:
Malaria is a prozotoan infection, that can be produced by several protozoan, in the genus Plasmodium. This Plasmodium infect red blood cells and the vector that trasmites it is the Anopheles mosquitoe. In this disease, red blood cells can have severe damage in different organs because of the hemolysis.
Toxoplasmosis is a disease caused by the protozoan Toxoplasma gondii. The main vector of them are domestic cats. When cats are infected, T. gondii oocysts is found in their feces and it can spread to humans. This disease is generally asymptomatic, except when the patient has AIDS or in pregnancy, which can be very dangerous and fatal.
Chagas disease, or American trypanosomiasis is caused by protozoan Trypanosoma cruzi and is generally transmitted to people thanks to the feces of triatomine bugs. Some of the acute symptoms include fever, vomiting, headache, and in severe cases people can develop a chronic disease. In the worst cases it can produce flaccid cardiomegaly (enlargement of the heart) leading to heart failure and death.
