Anabolism: The Constructive Phase of Metabolism

Anabolism is the constructive phase of metabolism. It is the set of metabolic pathways whose objective is to obtain more or less complex organic molecules, sharply reduced, from simpler and relatively oxidized ones. Therefore, these are chemical reduction processes.

Features of Anabolic Pathways

• As we have said, they are basically chemical reduction processes.
• Reactions are strongly endergonic (energy is needed), for which they use the energy released in catabolic reactions as ATP, NADH, and NADPH.
• The anabolic pathways for the synthesis of molecules are different from the catabolic ones, although they often share reversible reactions close to equilibrium. There is always some different way on each

Following the First World War (1914-1918), the peace treaties signed between nations proved weak and unfair to some countries, leading to widespread discontent and a desire for revenge. The Treaty of Versailles significantly reduced the territories of Germany and Austria, including areas populated by Germans. Great ambition and rivalry arose between countries, especially those that had lost territory in the Great War.

The need to demonstrate military power to achieve a superior military and political position over other countries fueled tensions. Control and domination of certain areas were sought to exploit their natural wealth. Hitler envisioned a terrestrial version of England's maritime power.

Ethnic issues also played a significant role,... Continue reading "World War II: Causes, Key Events, and Global Impact" »

Vision Development in Infants

The visual system is designed to capture light effects. The apparatus of global vision allows us to perceive images based on the amount of light reflected. Light enters through the cornea, passes through the pupil to the lens, and is then sent to the retina.

Developmental Milestones

• 1 Month: Can stare at a large object.
• 2 Months: Can accommodate and converge their vision.

Operating Systems

If you have a computer, then you have heard about operating systems. Any desktop or laptop PC that you buy normally comes pre-loaded with Windows XP. Macintosh computers come pre-loaded with OS X. Many corporate servers use the Linux or UNIX operating systems. The operating system (OS) is the first thing loaded onto the computer. Without the operating system, a computer is useless. At the simplest level, an operating system does two things:

• It manages the hardware and software resources of the system. In a desktop computer, these resources include such things as the processor, memory, and disk space. On a cell phone, they include the keypad, the screen, the address book, the phone dialer, the battery, and the network connection.

Company Organization

The formal organization is the intentional setting that is made of the different tasks and responsibilities, fixing its structure so as to achieve the objectives set by the company.

The informal organization comprises a network of informal relationships that occur in the business field and have not been planned by management or established previously.

Synergy means cooperation. Synergy generates a greater overall effect than the sum of the effects that occur in each part separately.

• Functional
