Biology

Luba_88 [7]3 years ago
4 0

Answer:

The correct answer is option e. "result in permanent activation of Ras".

Explanation:

Ras function is regulated by the GTP/GDP cycling rate, in a way that Ras is inhibited by the substrate GDP. Once Ras hydrolyzes GTP, GDP is produced and Ras is inhibited by GDP. A mutation that inhibits Ras from hydrolyzing GTP, would lock Ras in a permanently activated state because no GDP would be produced and there will be no substrate to inhibit Ras.

bearhunter [10]

Answer:

The endomembrane system includes Golgi apparatus, lysosomes, ribosomes, and the endoplasmic reticulum.

Explanation:

The endomembrane system has some very important function, but mostly it's on a charge of the internal transportation of "things" inside the cell. The system not only transports proteins or RNA or lipids, but it also transports what the cell no longer needs (waste). It starts with the endoplasmic reticulum close to the nucleus, where ribosomes are attached, so it receives molecules from inside the nucleus and also as proteins are synthesized in the ribosomes, therefore it also transports them to the next step which is the Golgi apparatus. The Golgi wraps molecules in a lipid layer and then they are taken to their final destination. Finally, lysosomes process big molecules and take them to a place in the endomembrane system so it can be treated as said before.

Stimulants are substances that can affect a person's mood, often giving the user extra energy and a stronger sense of well-being. They can range from legal substances such as nicotine and caffeine to illegal drugs like cocaine and methamphetamine.
