Where do the electrons entering photosystem ii come from?

Biology
1 answer:
dangina [55]3 years ago
8 0

In photosystem ║, the chlorophyll molecules releases 2 energized electrons; the electrons are placed by 2 electrons from a water molecule,forms oxygen gas (o2) and 2 hydrogen ions.

Explanation:

Photosystem ║is the protein complex in the light dependent reactions of oxygenic reactions of photosynthesis. The energized ions are replaced by oxidizing water to form hydrogen ions and molecular oxygen.

During photosystem ║, light strikes a photosynthetic pigment, the absorbed energy bounces to the chlorophyll molecules in the reaction center, it releases two energized electrons, the electrons are placed by two electrons stripped from a water molecule, forming oxygen gas(02) and 2 hydrogen ions.

The energized electrons are transferred to plastoquinone and are used to reduce NADPH are used in non- cyclic electron flow.

When NAD+ becomes NADH, it is being
ipn [44]

NAD+ accepts a hydrogen ion (H+) and two electrons (2e−), as it becomes reduced to NADH + H+. The NADH moves to the electron transport chain and donates a pair of electrons (becomes oxidized) to the first compound in the chain.

Breathing into and out of a paper bag for a long period of time will lead to?
Ilya [14]

Breathing into and out of a paper bag for a long period of time will lead to respiratory acidosis.

<h3>What is respiratory acidosis?</h3>
  • When the lungs are unable to expel all of the carbon dioxide the body produces, a condition known as respiratory acidosis develops.
  • Body fluids, particularly the blood, become too acidic as a result.
  • The main causes of respiratory acidosis are inadequate ventilation and carbon dioxide buildup.
  • The main issue is an increase in arterial carbon dioxide partial pressure (pCO2) and a decline in the arterial bicarbonate to arterial pCO2 ratio, which causes a drop in blood pH.
  • When there is acute respiratory acidosis, the body initially tries to make up for it.
  • If the acidosis lasts more than 12 hours, a reaction known as metabolic compensation2 takes place.
  • By increasing the release of hydrogen ions through ammonium, the kidneys will lower the blood's acidity.
  • Too much carbon dioxide in the body can result in general symptoms including headache, exhaustion, and twitching muscles.
  • Frequently, it goes away fast on its own.
  • But in cases of severe hypercapnia, the body is unable to return to a stable CO2 level, and the symptoms are more severe.

What is the small unit of matter that has characteristics properties of this element?
Vikentia [17]

The smallest unit of matter that has the characteristic properties of it’s element is called an “atom”.

Individual atoms are called “elements” for that reason.

There are smaller divisions of matter, however those no longer have the characteristics of the element that they may be a part of. A hydrogen electron is indistinguishable from an argon electron, or any other.

the efficiency of aerobic metabolism is greater than that of anaerobic metabolism even though much more energy is released in ae
Nitella [24]

Compared to anaerobic metabolism, aerobic metabolism retains a lot additional energy in the manner of ATP.

<h3>What is the straightforward meaning of metabolism?</h3>

the alterations in an organism's or a cell's chemistry. These modifications generate the ingredients and energy that cells and organisms require to develop, procreate, and maintain health.

<h3>Does weight change with metabolism?</h3>

You will consume more calories both at rest and when you are active if overall metabolism is "strong" (or quick). You'll need to consume more calories to maintaining your weight if you have a strong metabolism. That is one of the reasons why some people are able to consume more than before without putting on weight.
