Cellular Respiration: Krebs Cycle, Electron Transport, and Fermentation
Krebs Cycle
The Krebs cycle is the common pathway in all aerobic cells for the complete oxidation of carbohydrates, fats, and proteins. It can also be the starting point of biosynthetic reactions. This is because there are intermediate metabolites, which may go to the cytosol and act as anabolic precursors. In this sense, we say that the Krebs cycle is amphibolic. The process involves the complete oxidation of acetyl-CoA, which is excreted as carbon dioxide. The e-/H+ obtained in the successive oxidations

1. The Cycle of Rocks
Internal processes lead to the formation of new rocks and the formation of relief. External processes cause wear, sediments are deposited in the basins, and new rocks are formed. The geological cycle describes the geological processes that contribute to the generation of rocks, acting upon each other in a succession of events, ordered or not.
Milestones:
- Orogeny: Mountain range formation, relief, and inner strength from within to the exterior.
- Gliptogenesis: Destruction of geological
Physical Education: Fundamental Skills and Concepts
**Basic Physical Education Concepts**
**1. Objective of Coordination**
Coordination aims to develop and enrich the individual’s reaction possibilities, increasing freedom and ease of movement.
**2. Basic Contents for Oculo-Pedal Coordination**
Based on locomotor skills, the development of oculo-pedal coordination is achieved through perceptual-motor skills such as: throws, stops, and strikes.
**3. Notes on Gross Motor Skills**
Gross motor skills include displacement, jumps, turns, throws, receptions,

1.1 – What is Finance?
Finance affects the lives of all people and organizations.
- At the macro level, it is the study of financial markets and the financial system, nationally and internationally.
- At the micro level, studies are the financial planning of your organization, such as making decisions based on its balance sheet, evaluating and recommending the acquisition of assets, and profit maximization.
Finance, as the art and science of money management, involves virtually all individuals and organizations

**Human Intervention in Natural Systems**
_Homo sapiens_ underwent a type of development and evolution based on science and technology that allows us to use nature and science to meet our needs. We can transform nature beyond what corresponds to the biological scale. The adaptive success of our species has replaced cultural evolution with biological evolution. Civilization:
- Consumes increasing amounts of energy
- Exploits natural resources
- Degrades exhaustible natural resources with their wastes, impacting
Java Development: Key Concepts and Best Practices
ArrayList vs. TreeSet
When are the differences between an ArrayList and a TreeSet?
A: An ArrayList allows duplicate elements and maintains the insertion order, while a TreeSet does not allow duplicate elements and does not maintain the insertion order.
Object-Relational Mapping (ORM)
Explain what Object-Relational Mapping is.
A: It is a sophisticated mechanism for mapping Java objects in memory to tables in a relational database. It allows you to persist objects, enables complex queries, and each instance

Smooth Muscle Cells
Smooth muscle cells are the simplest of the three muscle types.
-
Aspect
- Smooth muscle cells are fusiform, elongated, with sharp ends and an enlarged central portion with an elongated nucleus.
- Most are 5-20 µm in diameter (and up to 200 µm in the gravid uterus), and their length can vary between 20 µm and 1 mm or more (e.g., in the gravid uterus).
- These descriptions are of isolated cells, as they usually form narrow beams and homogenous bundles, making it difficult to see their
Major Ethical Theories: From Aristotle to Habermas
Aristotle’s Ethics
According to Aristotle, humans are composed of body and soul. The soul is divided into three parts: the vegetative, the animal, and the rational.
Most human beings must be content with operating their vegetative-animal soul, whose aim is to achieve virtue ethics through action and the achievement of habits. These habits of action must be correct and always aim for the average. This means that one must never fall into a vice, either by default or by excess.

Classification of Non-Ferrous Metals
Non-ferrous metals are essential and are increasingly used in industry to manufacture many products. They are classified as follows:
- Heavy: Density greater than 5 kg/dm3. Examples include tin, copper, zinc, and lead.
- Light: Density between 2 and 5 kg/dm3. Examples include aluminum and titanium.
- Ultralight: Density less than 2 kg/dm3. Examples include magnesium and beryllium.
Non-ferrous metals are generally soft and have low mechanical strength. Therefore, they are

Thomas Aquinas
Historical Framework
Thomas Aquinas belongs to the Late Medieval era (11th-15th centuries). This period marked Europe’s awakening after the Dark Ages. Christianity revolved around two major powers: the Emperor and the Pope. Constant clashes arose due to overlapping spheres of influence, both seeking political dominance. The Concordat of Worms (1122), settling disputes between Emperor Henry IV and Pope Gregory VII, recognized papal superiority, yet conflicts resurfaced. By the 13th century,
