Question

Because of the great deal of active transport that occurs here, the _________ of all the nephrons collectively account for about 6% of one's daily resting ATP and caloric consumption.

Answer 1

Answer:

Because of the great deal of active transport that occurs here, the proximal convulated tubules of all the nephrons collectively account for about 6% of one's daily resting ATP and caloric consumption.

Explanation:

Proximal convulated tubule is responsible for transport of a very large number of substances mentioned below :

• Sodium bicarbonate
• Sodium Chloride
• Glucose
• Amino acid
• Organic solutes
• K ions are absorbed via paracellular pathway.
• Water is absorbed passively.

Transporters include :

• Na/K transporter
• Na/HCO3 transporter
• Na/glucose
• Na/Amina acids

As a large number or transporters are present in the PCT , large amouny of ATP is cleaved here, and about 6% of daily resting ATP and caloric consumption occurs.
