You have discovered a cell type in humans that has an unknown function. The cells are found in the epithelium of the lungs. It a

ppears that upon stimulation these cells deliver a set of highly glycosylated proteins to the extracellular space. However, several individuals who are highly susceptible to lung infections appear to have decreased secretion of these glycosylated proteins. Which of the following would provide you with the best method of inhibiting this secretory pathway in a normal functioning lung cells with stimulation?a) decrease the amount of GTP to inhibit microtubule elongation and block secretionb) treat the cells with taxol to rid the cell of microtubules and block secretionc)treat the cells with nocodazol to stabilize the microtubule pathways for visualizationd)inhibit the GTPase activity of the heterodimer to cause microtubule catastrophe and block secretion

Answer:

The correct option is a) "decrease the amount of GTP to inhibit microtubule elongation and block secretion"

Explanation:

Since microtubules play a critical role in transporting secretory vesicles, preventing it from elongating will keep it from performing this function. Completely eliminating the microtubules from the cell as suggested in option d will harm the cells and other processes in it because the microtubules also have an integral part to play in maintaining cell shape & structure.

Hope that answers the question, have a great day!

Which of these pollutants is biodegradable?
vfiekz [6]

Answer:

Food waste

Explanation:

Food waste is an organic compound, unlike the other choices. Organic compounds are biodegradable because living organisms, such as decomposers, have evolved mechanisms of breaking down these large carbon-based compounds/polymers into smaller molecules for energy. Food waste is therefore easily recycled into the environment.

The others do not have naturally occurring organisms to break them down or reduce them. They would, therefore, accumulate in the environment. This is exactly what is happening to plastc pollution. Accumulation of plastic in the environment is due to fact that they are not broken down into simpler molecules by any naturally occurring bacteria or organisms in the environment.
