<h2>Photosynthesis </h2>

Explanation:

Photosynthesis is the process by which photosynthetic organisms transform light energy into chemical energy
Photosynthesis is an oxidative reductive metabolic pathway in which water is oxidized and carbon dioxide is reduced to carbohydrates
Light reaction of photosynthesis is concerned with light dependent oxidation of water and synthesis of high energy compounds such as ATP and NADPH
All proteins and cofactors which involves in light reaction are present in thylakoid membrane hence light reaction of photosynthesis completed in thylakoid membrane
Transfer of electron and protons in thylakoid membrane is carried out by four protein complexes and two mobile electron carriers
Oxidation of one water molecule generates two electrons, two protons and one atom of oxygen
Transfer of one electron from Photosystem II (PSII) to Photosystem I (PSI) requires one photon and transfer of one electron from PSI to NADP+ requires one photon, thus transfer of two electrons from PSII to NADP+ requires four photons
Flow of two electrons from cytochrome b6f complex drives transportation of four protons from stroma to lumen
Thus oxidation of one water molecule establish gradient of 6 H+, gradient of 6 H+ drives synthesis of 2 ATP
Reduction of 1 NADP+ to NADPH requires two electrons, thus oxidation of one eater molecule generates 1 NADPH

Radda [10]

Answer:

Considering that homeostasis is restored in the patient, his blood pH range would return to normal levels (7.35-7.45), and his hydrogen ion concentration in the blood would normalize. The effect of normalizing the body by getting rid of excess hydrogen ions is achieved by concentrating these ions into the urine for expulsion, therefore increasing the pH levels of urine.

Explanation:

Acidosis is the condition wherein excessive acid build-up within the body causes the blood pH to become lower than normal (normal pH range 7.35-7.45). This may be due to an excessive loss of bicarbonate in the blood, also known as metabolic acidosis, or due to an impairment in the elimination of carbon dioxide in the blood from poor lung function, also known as respiratory acidosis. The body's natural response to acidosis is to increase the breathing rate to eliminate carbon dioxide in the blood, restoring the natural pH of the body.

In people with diabetes mellitus type I, the lack of insulin causes cells to breakdown fat aside from glucose as an energy source. This process produces ketones as a metabolic by-product for energy but also causes the body to be acidic. This is known as diabetic ketoacidosis.

Neville has low blood pressure and his pituitary started producing a homorone to maintain water balance his blood pressure event

ivanzaharov [21]

Answer: The options are missing in the question,the options are;

A) Positive feedback will stop the release of this hormone.

B) Positive feedback will speed up the release of this hormone.

C) Negative feedback will speed up the release of this hormone.

D) Negative feedback will stop the release of this hormone.

The correct answer to the question is option D

NEGATIVE FEEDBACK WILL STOP THE RELEASE OF THIS HORMONE.

Explanation: The hormone the will be produced is known as Antidiuretic hormone (ADH).it is otherwise known as VASOPRESSIN.It is secreted by the posterior lobe of the pituitary gland.

The main effect of Antidiuretic hormone is to reduce urine output,(diuresis is the production of large amount of urine). Antidiuretic hormone acts in the distal convulated tubules and the collecting ducts of the nephrons of the kidneys,it increases their permeability to water and more of the glomerular filtrate is reabsorbed. Antidiuretic hormone secretion is determined by the osmotic pressure of the blood circulating to the osmoreceptors in the hypothalamus.

As osmotic pressure rises,for example as a result of dehydration, secretion of Antidiuretic hormone increases. With this,there is Increased reabsorption of water reducing the amount of urine produced.This implies that more water is retained in the body making the rise in the osmotic pressure of the blood to be low,for example,after a large fluid intake, secretion of Antidiuretic hormone is reduced,less water is reabsorbed and more urine is produced.

At high concentrations,for example after severe blood loss, antidiuretic hormone causes smooth muscle contraction, especially vasoconstriction in small arteries.this has a pressor effect,raising systemic blood pressure.
