Reabsorption of filtered glucose from the lumen in the pct is largely by means of:______.
Alika [10]

Reabsorption of filtered glucose from the lumen in the pct is largely by means of: secondary active cotransport.

Nephron is the functional unit of the kidney associated with removing waste products from the blood. It achieves the function by performing filtration which results in formation of urine. A nephron is divided into two parts namely renal corpuscle and renal tubule. Renal corpuscle is associated with filtration and renal tubule mainly performs reabsorption.

Renal tubules are further divided into Proximal Convoluted Tubule (PCT), loop of Henle, Distal Convoluted Tubule (DCT) and collecting duct. PCT and DCT are mainly linked with reabsorption and secretion respectively. Reabsorption in PCT occurs via cotransport. Here, glucose is reabsorbed along with sodium ions via SGLT2 cotransporter. Specifically, the reabsorption method is termed as sodium-coupled secondary active transport.

Two different scientists were studying the carbon levels of the air above a large city. They both found that the levels had incr
ss7ja [257]

Answer:

Scientist 1

Explanation:

<em>The conclusion of scientists 1 is valid.</em>

Human activities such as burning of fossil fuels, agriculture, deforestation, etc. leads to the emission of carbon in the form of carbon dioxide into the atmosphere. <em>An increase in the population of a city will only lead to an increase in these activities and hence, an increase in the amount of carbon emitted into the atmosphere.</em>

Also, volcanic activities leads to the production of volcanic gases which is a mixture of carbon dioxide, oxides of sulfur, nitrogen, etc.

<u>However, an active volcano that is several miles away from the city might not be a major source of carbon in the air above a large city. The carbon dioxide produced from such volcanic activity thins out before reaching the city.</u>
