<span>It binds itself to the receptors present on the surface of the cell membrane, which activates the enzymes present inside cell. Then It passes through the cell membrane and attaches itself to a receptor protein present in the cytoplasm. It passes on the signal to the secondary messengers inside the cell, which activate the receptors on the cell membrane.</span>

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.

As a scientist, you seek to prove that DNA is the hereditary macromolecule by replicating the Hershey-Chase experiment. You cult
weeeeeb [17]

Answer:

The correct answer is option e. "None of the above".

Explanation:

The Hershey-Chase experiment helped to prove that DNA was the genetic material, by specifically labeling the DNA material of a bacteriophage with phosphorus-32. In this experiment the lambda phage is labeled with heavy and light Cl. CI-36, the one that is heavy and radioactive, corresponds to Chlorine-36. Chlorine is not an element found in DNA such as phosphorus, therefore lambda DNA will not be labeled and no radioactivity will be detected.
