were detected at the following times and locations: 5 minutes: rough ER; 10 minutes: Golgi apparatus; 40 minutes: endosomes; 70 minutes: lysosomes; 140 minutes: lysosomes. Which of the following conclusions can be drawn from these results?
A) The proteins were secreted.
B) The proteins traveled from lysosomes to endosomes.
C) The proteins did not travel through the Golgi apparatus.

Answer:

The correct answer is: D) The final destination of the proteins was the lysosome.

Explanation:

The experiment was used to determine the location of certain proteins, and the results indicate that their last stop was in lysosomes, where they remained for at least 70 minutes.

Lysosomal proteins make up around 60 types of enzymes that are made in the rough endoplasmic reticulum. To reach the lysosomes, these proteins are specifically tagged by the Golgi apparatus with the molecule <em>mannose 6-phosphate</em>.

Lysosomal enzymes <u>have the capacity to break down biomolecules</u> and, to do so, they require an acidic environment.

Compare and contrast the soil in the desert to the soil in the rain forest
Zinaida [17]

Soils of the Tropical Rain forests. Soils here tend to be deep because the warm temperatures and often high rainfall lead to strong weathering of the parent rock to form soil. They tend to be reddish in color because of the way that the iron minerals in them respond to the hot climate. hope this was helpful <3

Renin hydrolyzes angiotensinogen, which is released from the _________, to form angiotensin i.
tia_tia [17]

Renin is an enzyme that helps control blood pressure and regulate levels of sodium and potassium in the body. Angiotensinogen is the hormone that causes the narrowing of blood vessels. It is released from liver to form angiotensin.

<h3>What is the role of angiotensin?</h3>

Angiotensinogen is a hormone that on hydrolysis forms angiotensin

Angiotensinogen is hydrolyzed by renin enzyme and forms angiotensin.

This angiotensin helps to increase blood pressure by the process of vasoconstriction,  increased aldosterone biosynthesis and renal actions.

Thus, it can be concluded renin hydrolyzes angiotensinogen, which is released from the liver, to form angiotensin.
