What role does ubiquinone have in electron transport and what is the mode of action?

Biology
1 answer:
nekit [7.7K]3 years ago

Answer:

The ubiquinone (coenzyme Q) can act as a bridge between a 2-electron donor and a 1-electron acceptor, in addition, since Q is a small and hydrophobic molecule, it can diffuse through the inner mitochondrial membrane and act as a shuttle reduction equivalents among other less mobile conveyors.

Explanation:

In relation to the mitochondrial respiratory chain, ubiquinone (Q) acts as a mobile electron acceptor between enzyme complexes, ensuring adequate electronic transport to oxygen. On the other hand, it also participates in the generation of the chemosmotic gradient of protons through the mitochondrial inner membrane, so it has a main function in the synthesis of ATP. In addition, ubiquinone interacts with other molecules that provide electrons, such as the electron transfer protein of β-oxidation of fatty acids. For this key function in energy metabolism to develop properly, it is necessary not only the presence of ubiquinone in adequate concentrations, but also the integrity of the inner membrane of the mitochondria (phospholipids and ubiquinone binding proteins that are part of the structure of the respiratory chain). Electronic transport through ubiquinone is carried out thanks to the interconversion of this molecule in its oxidized (Q; electron-acceptor), reduced (QH2: electron donor) and ubisemiquinone (Q-) forms, and the ability to displacement of ubiquinone through the phospholipid environment of the inner membrane of the mitochondria.

Discuss how heat stroke, acquired during extreme physical exercise, disrupts the feedback loop and the impact this disruption ha
Vera_Pavlovna [14]

Answer:

Heat stroke is acquired during extreme physical exercise when the environment is hot, strenuous activity, excess clothing and tight clothing, drinking alcohol and smoking during a hot season or environment,when you are dydrated and not drinking water. Some medication and age also add to having heat stroke.

It causes disrupts in the feedback loop because it doesn't form a circular chain. It can be both positive and negative chain. Feed back loop is known to be either negative or positive channel or pathway formed by an effects.

The impact and disruption it has on human physiology

1.it causes brain damage

2.it leads to death

3.it also causes vital organ damage

Explanation:when the environment is hot, it makes you heat up fast when exercising and increase your temperature because the atmospheric temperature is high,and when exercising in this condition without air conditioner to cool your surroundings it leads to heat stroke.

When wearing heaving clothing and tight clothing during physical exercise it makes you to not lose moisture and makes air not easily passed to you, this causes your body to heat up fast and thereby causing heat stroke.

When dydrated and not drinking water causes you to overwork you body and not cool it down, it leads to heat stroke.

Heat stroke causes brain damage, leads to death when not taken immediately or rush to the health center or hospital.

.<br> Which causes the pH of a solution to increase?
tamaranim1 [39]

Diluting an acid decreases the concentration of H+(aq) ions , which increases the pH level of the solution towards 7 , making it less acidic . However , the pH level of an acidic solution cannot become greater than 7 , because the water you add to dilute it is not alkaline .

How do global winds affect climate?
Vlad1618 [11]
These global wind systems, in turn, drive the oceans' surface currents. Unequal heating of the Earth's surface also forms large global wind patterns. In area near the equator, the sun is almost directly overhead for most of the year. Warm air rises at the equator and moves toward the poles ((from google))
