Metabolic Pathways: Urea Cycle, Beta-Oxidation, and TCA Cycle
Role of the Urea Cycle in Nitrogen Removal
The urea cycle is a series of biochemical reactions that removes excess nitrogen from the body by converting it into urea. Urea is then excreted in the urine.
How the Urea Cycle Works
- Ammonia is created from amino acids.
- The liver’s mitochondria convert ammonia into urea.
- Urea enters the bloodstream.
- The kidneys filter urea out of the blood.
- Urea is removed from the body in urine.
Why the Urea Cycle is Important
- The urea cycle is the main way the body removes excess

Centrosome: Structure and Functions
The centrosome is a dense material, often referred to as the centrosphere, with few radial microtubules. Each centriole consists of nine groups of microtubule triplets arranged as a cylinder, held together by proteins. These triplets remain united by proteins.
Functions:
- Microtubule organizing centers.
- Involved in the formation of cilia and flagella.
- Forms the mitotic spindle during cell division.
- Contributes to the structure of the cytoskeleton.

Theory of Plate Tectonics
This theory proposes the dynamics of the Earth based on several key factors:
- Ocean floor
- Lithospheric plates
- Plate boundaries
- Lithospheric dynamics
Ocean Floor Dynamics
Oceans cover 71% of the planet’s surface. Beneath the waves lies an underwater relief known as the oceanic ridge, where sediments are scarce.
