At the site of the rough endoplasmic reticulum, proteins that are destined for secretion are manufactured. Insulin is a protein-

based hormone made by cells in the pancreas. Which type of vesicular transport is involved with the exporting of these protein-based hormones into the bloodstream?

Answer:

The type of vesicular transport involved in the exporting of protein-based hormones, such as insulin, into the bloodstream is regulated exocytosis.

Explanation:

In general terms, exocytosis is a type of active transport that allows intracellular substances are released to the extracellular space, through of vesicles that fuse with the plasma membrane, which allow the exit of substances from inside the cell.

Regulated exocytosis is the specific vesicular transport for the secretion of substances, such as hormones. For this type of transport to exist, the presence of an extracellular signal is required, which will activate the fusion of the vesicles.

In the case of insulin, the external signal originates with the increase in blood glucose levels, a signal that penetrates the intracellular space and generates an increase in insulin production in the islets of Langerhans (pancreas).

Before insulin secretion occurs, the cell must be depolarized, allowing calcium to enter, which promotes transport by regulated exocytosis of insulin to the extracellular space.

Which term best describes the difference in colors of the birds below?
NeX [460]

Answer:

<u><em>The correct option is C) genetic variation</em></u>

Explanation:

Genetic variation can be described as the differences present in the genetic material i.e DNA of organisms present in a population. Genetic diversity allows organisms of a species to better adapt to an environment. A population in which the genetic variability is scarce might become wiped out by a disease or an invading predator.

As the birds show different variations hence the term that best described them is genetic variation.

Ghella [55]

Answer:

The answer is spongy mesophyll.

Explanation:

Between the upper and lower epidermis of a leave, you can find the so called mesophyll tissue which is rich in chloroplasts. There are two types of mesophyll tissue: the palisade and the spongy mesophyll. Whereas the cells of the palisade mesophyll are tightly packed, the cells of the spongy mesophyll are loosely packed.

Zigmanuir [339]

Answer:

Chloroplast and mitochondria

Explanation:

Chloroplasts are organelles present only in plant cells and algae in regions that become illuminated. They are green in color due to the presence of chlorophyll and are responsible for photosynthesis. Chloroplasts produce ATP in the presence of sunlight and therefore the heaviest fractions should contain these organelles.

Mitochondria are cellular organelles related to the process of cellular respiration. They are often referred to as “powerhouses” of cells because, through the cellular respiration process, a large amount of ATP is generated. Mitochondria do not need light to produce ATP, so it is likely that these organelles are present in the lightest fractions.

Thepotemich [5.8K]

Answer:

B. The amount of unbound cyclin E is lowest as the cell enters S.

Explanation:

The reproduction of the cell is a cycle that it regulates by itself, depending the  demand of a certain cell.

In the case of the mitosis, in Each change from G1 to S to G2 to M is regulated by some proteins like the cyclin.

In the case of the cdK2 is ncessary to pass the control point to pass from the stage G1 to the stage S.

Another characteristic of the cyclins, is that these proteins are synthetized and degraded constantly during the hole process.

Hope this is a useful info
