Answer:
The reduced form of cytochrome c more likely to give up its electron to oxidized cytochrome a having a higher reduction potential.
Explanation:
Electrons from NADH and FADH2 flow spontaneously from one electron carrier of the electron transport chain to the other. This occurs since the proteins of the ETC are present in the order of increasing reduction potential. The reduced cytochrome b has lower reduction potential than cytochrome c1 which in turn has a lower reduction potential than the cytochrome c.
Cytochrome c is a soluble protein and its single heme accepts an electron from cytochrome b of the Complex III. Now, cytochrome c moves to complex IV which has higher reduction potential and donates the electron to cytochrome a which in turn passes the electrons to O2 via cytochrome a3.
The answer is C. Pheromones are hormones (which are proteinous) produces by individuals of the same species and are a means to send communication signals for social interactions. They signal alarm, food and even sex. Sex pheromones are released by females beetles into the environment to signal their availability for mating. The pheromones are picked up by receptors on the male beetles and this is how they find the females.
Answer:
The answer is b. Both of them are characterized by selective permeability.
Explanation:
- Option a. states that both, the nuclear and the cell membrane have two layers. This is only true for the nuclear membrane that consists of two lipid bilayers whereas the plasma membrane only contains one layer.
- c. Only the nuclear membrane has nuclear pores that connect the two bilayers. The pores act as protein channels or passages that allow transport of materials. The cell membrane does contain channel proteins or transmembrane proteins but not protein channels.
- d. The nuclear membrane separates nuclear contents from the cytoplasm whereas the cell membrane separates cellular contents from the extracellular environment.
Answer:
Answer is hemolytic anemia.
Explanation:
Hemolysis is the destruction of red-blood cells, while anemia when the amount of the red blood cells in the body is lower than the expected or normal.
Therefore, hemolytic anemia can be defined as a disorder or situation where the rate at which the red blood cells are destroyed is faster compared to the rate at which they are made or produced.
This can be caused by bone marrow failure or infections, and inherited blood disorder like sickle cell disease.
The hemolytic anemia is a serious disorder that can damage the heart and other organ of the body, this is because of oxygen starvation, since the red blood cells responsible for carrying oxygen around the body have been affected.
Eating some food items like beans, green vegetables, red meat and legumes can increase red blood cell count.
