It provides structure to the body. With our our strong healthy bones to support us, we would just be walking skin bags with organs and hair. The bones give us the legitimate support for everything, the muscles attach to the bones, so while it may feel like your muscles are doing all of the work, they aren’t. Your bones play a huge roll, in you everyday moving. What makes bones stronger? MILK!

All cells share the following common components except
Monica [59]

Answer:

All cells share four common components: (1) a plasma membrane, an outer covering that separates the cell’s interior from its surrounding environment; (2) cytoplasm, consisting of a jelly-like region within the cell in which other cellular components are found; (3) DNA, the genetic material of the cell; and (4) ribosomes, particles that synthesize proteins. However, prokaryotes differ from eukaryotic cells in several ways.



Figure 1. This figure shows the generalized structure of a prokaryotic cell.

A prokaryotic cell is a simple, single-celled (unicellular) organism that lacks a nucleus, or any other membrane-bound organelle. We will shortly come to see that this is significantly different in eukaryotes. Prokaryotic DNA is found in the central part of the cell: a darkened region called the nucleoid (Figure 1).

Unlike Archaea and eukaryotes, bacteria have a cell wall made of peptidoglycan, comprised of sugars and amino acids, and many have a polysaccharide capsule (Figure 1). The cell wall acts as an extra layer of protection, helps the cell maintain its shape, and prevents dehydration. The capsule enables the cell to attach to surfaces in its environment. Some prokaryotes have flagella, pili, or fimbriae. Flagella are used for locomotion, while most pili are used to exchange genetic material during a type of reproduction called conjugation.

Eukaryotic Cells

In nature, the relationship between form and function is apparent at all levels, including the level of the cell, and this will become clear as we explore eukaryotic cells. The principle “form follows function” is found in many contexts. It means that, in general, one can deduce the function of a structure by looking at its form, because the two are matched. For example, birds and fish have streamlined bodies that allow them to move quickly through the medium in which they live, be it air or water.

A eukaryotic cell is a cell that has a membrane-bound nucleus and other membrane-bound compartments or sacs, called organelles, which have specialized functions. The word eukaryotic means “true kernel” or “true nucleus,” alluding to the presence of the membrane-bound nucleus in these cells. The word “organelle” means “little organ,” and, as we learned earlier, organelles have specialized cellular functions, just as the organs of your body have specialized functions.

Cell Size

At 0.1–5.0 µm in diameter, prokaryotic cells are significantly smaller than eukaryotic cells, which have diameters ranging from 10–100 µm (Figure 2). The small size of prokaryotes allows ions and organic molecules that enter them to quickly spread to other parts of the cell. Similarly, any wastes produced within a prokaryotic cell can quickly move out. However, larger eukaryotic cells have evolved different structural adaptations to enhance cellular transport. Indeed, the large size of these cells would not be possible without these adaptations. In general, cell size is limited because volume increases much more quickly than does cell surface area. As a cell becomes larger, it becomes more and more difficult for the cell to acquire sufficient materials to support the processes inside the cell, because the relative size of the surface area across which materials must be transported declines.



Figure 2. This figure shows the relative sizes of different kinds of cells and cellular components. An adult human is shown for comparison.

IN SUMMARY: COMPARING PROKARYOTIC AND EUKARYOTIC CELLS

Prokaryotes are single-celled organisms of the domains Bacteria and Archaea. All prokaryotes have plasma membranes, cytoplasm, ribosomes, a cell wall, DNA, and lack membrane-bound organelles. Many also have polysaccharide capsules. Prokaryotic cells range in diameter from 0.1–5.0 µm.

Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions. Eukaryotic cells tend to be 10 to 100 times the size of prokaryotic cells.

Why do both high levels and very low levels of insulin lead to increased eating?.
abruzzese [7]

Both high levels and very low levels of insulin lead to increased eating because little glucose is reaching the cells to be used as fuel.

<h3>How do insulin levels affect apatite?</h3>

Cells will absorb too much glucose from the blood if a person's insulin level rises over what is necessary, such as when they spend more energy than expected or eat less than they had planned. An abnormally low blood glucose level (hypoglycemia) results from this . As a response to hypoglycemia, the body releases liver-stored glucose in an effort to restore normal blood sugar levels. Elevated insulin levels result in greater appetite, enhanced enjoyment of sweet tastes, and higher food intake.

Type 1 diabetics either produce very little insulin or none at all. This illness is brought on by the beta cells' inability to produce insulin due to antibody destruction (antibodies are typically molecules the body releases to fight infections). High blood glucose levels result from the body's inability to transport glucose from the blood into the cells when there is insufficient insulin in the body. If the glucose is not reaching the cells, the person will eat more.

I understand the question you are looking for is this:

Why do both high levels and very low levels of insulin lead to increased eating?

  1. Glucose leaves the blood to be stored as fat.
  2. Fat supplies are being rapidly converted to glucose.
  3. Activity of the taste buds is directly enhanced.
  4. Little glucose is reaching the cells to be used as fuel.
