movement of the earthworm is CALLED segmentation.

Explanation:

Each segment has BRISTLES called SETAE which CONTROL or HELP the worm to move through soil.

We turn now to a different mechanism of enzyme regulation. Many enzymes acquire full enzymatic activity as they spontaneously fold into their characteristic three-dimensional forms. In contrast, other enzymes are synthesized as inactive precursors that are subsequently activated by cleavage of one or a few specific peptide bonds. The inactive precursor is called a zymogen (or a proenzyme). A energy source (ATP) is not needed for cleavage. Therefore, in contrast with reversible regulation by phosphorylation, even proteins located outside cells can be activated by this means. Another noteworthy difference is that proteolytic activation, in contrast with allosteric control and reversible covalent modification, occurs just once in the life of an enzyme molecule.

Specific proteolysis is a common means of activating enzymes and other proteins in biological systems. For example:

1.

The digestive enzymes that hydrolyze proteins are synthesized as zymogens in the stomach and pancreas (Table 10.3).

2.

Blood clotting is mediated by a cascade of proteolytic activations that ensures a rapid and amplified response to trauma.

3.

Some protein hormones are synthesized as inactive precursors. For example, insulin is derived from proinsulin by proteolytic removal of a peptide.

4.

The fibrous protein collagen, the major constituent of skin and bone, is derived from procollagen, a soluble precursor.

5.

Many developmental processes are controlled by the activation of zymogens. For example, in the metamorphosis of a tadpole into a frog, large amounts of collagen are resorbed from the tail in the course of a few days. Likewise, much collagen is broken down in a mammalian uterus after delivery. The conversion of procollagenase into collagenase, the active protease, is precisely timed in these remodeling processes.

6.

Programmed cell death, or apoptosis, is mediated by proteolytic enzymes called CASPASES, which are synthesized in precursor form as procaspases. When activated by various signals, caspases function to cause cell death in most organisms, ranging from C. elegans (Section 2.4.3) to human beings. Apoptosis provides a means sculpting the SHAPES of body parts in the course of development and a means of eliminating cells producing anti-self antibodies or infected with pathogens as well as cells containing large amounts of damaged DNA.

Table 10.3. Gastric and pancreatic zymogens.

Table 10.3

Gastric and pancreatic zymogens.

We next examine the activation and control of zymogens, using as examples several digestive enzymes as well as blood-clot formation.

Go to:

10.5.1. Chymotrypsinogen Is Activated by Specific Cleavage of a Single Peptide Bond

Chymotrypsin is a digestive enzyme that hydrolyzes proteins in the small intestine. Its mechanism of action was DISCUSSED in detail in Chapter 9. Its inactive precursor, chymotrypsinogen, is synthesized in the pancreas, as are several other zymogens and digestive enzymes. Indeed, the pancreas is one of the most active organs in synthesizing and secreting proteins. The enzymes and zymogens are synthesized in the acinar cells of the pancreas and stored inside membrane-bounded granules (Figure 10.31). The zymogen granules accumulate at the apex of the acinar cell; when the cell is stimulated by a hormonal signal or a nerve impulse, the contents of the granules are released into a DUCT leading into the duodenum.

The splitting or DECOMPOSITION of a chemical compound by means of light energy or photons. For example, the photolysis of water molecule in photosynthesis OCCURRED under the influence of light. When photons are absorbed, it causes the HYDROGEN to BIND to an acceptor, subsequently releasing the oxygen.

As Earth WARMS, the rate of evaporation and the ability of air to hold WATER vapor both rise, increasing the AMOUNT of water vapor in the air. Because water vapor is a GREENHOUSE gas, this leads to further warming. The melting of Arctic sea ice is another example of a positive CLIMATE feedback

A good soil structure is important to allow AIR and water into the soil which are vital for healthy plant GROWTH. It will improve drainage and reduce soil erosion caused by excess surface run-off. Without structure, soils will SUFFER from anaerobism, waterlogging and nutrient lock-up and, ULTIMATELY, plants will die!

At temperatures above 32°F (0°C), pure water ice melts and changes state from a solid to a LIQUID (water); 32°F (0°C) is the melting point. For most substances, the melting and freezing POINTS are about the same temperature.

0°C.

The melting point of ice is 0°C. The melting point of a solid is the same as the freezing point of the liquid. At that temperature, the solid and liquid states of the substance are in equilibrium. For water, this equilibrium OCCURS at 0°C.

Explanation:

• 1) The most important function of the nucleus is that it PROTECTS the genetic material of a cell.

• 2) Another important function of the nucleus is that gene expression is CONTROLLED by it.

• 3) The nucleus of a cell is also involved in mediating the replication process of DNA.

• The nucleus is described as a membrane bound structure in which the genetic material is enclosed. It is present only inside a eukaryotic cell.

The primary function of the respiratory system is to take in oxygen and eliminate carbon dioxide. Inhaled oxygen enters the lungs and reaches the alveoli. The layers of CELLS lining the alveoli and the surrounding capillaries are each only one cell thick and are in very CLOSE contact with each other. This barrier between air and blood averages about 1 micron (1/10,000 of a centimeter, or 0.000039 inch) in thickness. Oxygen passes quickly through this air-blood barrier into the blood in the capillaries. Similarly, carbon dioxide passes from the blood into the alveoli and is then exhaled.

Oxygenated blood travels from the lungs through the pulmonary veins and into the left side of the heart, which pumps the blood to the rest of the body (see Function of the Heart). Oxygen-deficient, carbon dioxide-rich blood returns to the right side of the heart through TWO large veins, the superior vena cava and the inferior vena cava. Then the blood is pumped through the pulmonary artery to the lungs, where it picks up oxygen and releases carbon dioxide.
