<span>First - carhydrates are composed by Carbon, Hydrogen and Oxygen. Carbohydrates often suffer reactions of reduction, oxdation, amination, esterification, which gives every structur a specific property such as solubility. Now, fats are composed by several fatty acids and form mono, digli and triglicerids. This last ones are formed by Carbon, Hydrogen and Oxygen with a (-COOH) structure at the extremity. Protein, formed by linear aminoacids chains. Irs structure is determined by the aminoacids sequence. Now, steroids are derivated from the sterane, composed by Cabron and Hydrogen forming 4 merged rings, 3 hexagonals and 1 pentagonal.</span>

Sometimes the microvilli on the epithelial cells lining the proximal tubule are destroyed. What effect would this have?
Aleonysh [2.5K]

Answer:

Reduced reabsorption of salts and nutrients from the proximal tubule.

Explanation:

The proximal convoluted tubules are the site for reabsorption of the largest amount of solute and water from the filtered fluid. It reabsorbs 65% of water, electrolytes such as Na+ and K+, almost 100% of the filtered glucose and amino acids and other electrolytes such as Ca2+, Mg2+, etc.

The simple cuboidal epithelial cells of the proximal convoluted tubule have a prominent brush border of microvilli on their apical surface. These microvilli serve to increase the surface area for reabsorption and secretion. Destruction of these microvilli would reduce the reabsorption of the above-mentioned salts and nutrients from proximal convoluted tubules.

egoroff_w [7]
During mitosis, chromosomes move to the middle of the spindle during metaphase. Mitosis is a type of cell division in which the parent cell divides into two daughter cells with each daughter cell receiving the same number of chromosomes as the parent cell.

Plasma contains more sodium than chloride. How can this be if individual ions of sodium and chloride exactly balance each other
MAXImum [283]

In addition to chloride, there are other negatively charged molecules in plasma. The extra sodium restores the balance of the overall negative charges.

So this is how plasma is electrically neutral.

<h3>The makeup of bodily fluids:</h3>
  • High levels of sodium, chloride, bicarbonate, and protein can be found in the plasma.
  • High levels of salt, chloride, and bicarbonate but a relatively low level of protein can be found in the IF.
  • The ICF, on the other hand, contains higher levels of protein, phosphate, magnesium, and potassium.
<h3>What occurs when the plasma Na+ content rises?</h3>
  • Although the plasma sodium concentration does not provide any information regarding the volume of extracellular fluid, it does allow for an assumption regarding intracellular volume.
  • A rise in plasma sodium (plasma osmolality) causes water to be drawn out of the cell, which causes the intracellular volume to decrease.
<h3>Why does plasma have a higher sodium content than chloride?</h3>
  • In plasma, sodium predominates over chloride.
  • In addition to chloride, there are other negatively charged molecules in plasma.
  • The extra sodium restores the balance of the overall negative charges.
