Answer:

Because of the great deal of active transport that occurs here, the <u>proximal convulated tubules</u> 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.

Which compound plays a pivotal role in both the first and last step of the TCA cycle? a. pyruvate b. oxaloacetate c. oxalate d.
vitfil [10]

Answer:

Option b oxaloacetate is the right one.

Explanation:

There are major eight steps in TCA cycle. Oxaloacetate plays a pivotal role in <u>first and eight step</u>s of cycle.

Step 1. In the first step of the citric acid cycle, acetyl CoA joins with a four-carbon molecule, oxaloacetate, releasing the CoA group and forming a six-carbon molecule called citrate.

Step 8. In the last step of the citric acid cycle, oxaloacetate—the starting four-carbon compound-is regenerated by oxidation of malate. Another molecule of NAD+ is reduced to NADH in the process.
