If the zygomatic arch was broken, where is this fracture located?

The Krebs cycle, also known as the citric acid cycle or tricarboxylic acid cycle, takes place in the mitochondrial matrix. Mitochondria are the powerhouses of the cell, responsible for generating ATP through aerobic respiration. The Krebs cycle is a key metabolic pathway occurring in the matrix of mitochondria, where acetyl-CoA molecules derived from the breakdown of carbohydrates, fats, and proteins are further oxidized to produce ATP, NADH, FADH2, and carbon dioxide. These energy-rich molecules serve as substrates for the electron transport chain, leading to the production of additional ATP molecules.

Water is the major component of blood plasma, making up approximately 90-92% of its composition by volume. Blood plasma is the liquid portion of blood, composed mostly of water along with dissolved solutes, such as ions, nutrients, gases, hormones, and waste products. Water in blood plasma serves as the solvent for carrying nutrients, hormones, and other molecules throughout the body, facilitates gas exchange in the lungs and tissues, helps regulate body temperature, and maintains blood volume and pressure. The remaining components of blood plasma, including ions (such as sodium, potassium, and calcium), proteins (such as albumin, globulins, and fibrinogen), and other solutes, contribute to various physiological functions in the body.

The xiphoid process is a small, cartilaginous extension at the inferior end of the sternum, also known as the breastbone. It is the smallest and most inferior part of the sternum and serves as an attachment site for some abdominal muscles and the diaphragm, a large muscle involved in breathing. The xiphoid process may vary in size and shape among individuals and tends to ossify (turn into bone) with age. It plays a role in stabilizing the sternum and protecting underlying structures in the abdomen.

The flagellum is a whip-like structure found in many single-celled protists, bacteria, and sperm cells of animals. Its primary purpose is propulsion, enabling the cell to move through its environment. The flagellum achieves propulsion by undergoing a whip-like motion, either beating rhythmically to propel the cell forward or rotating like a propeller. This movement allows the cell to navigate toward nutrients, avoid harmful substances, or seek optimal environmental conditions for survival and reproduction.
