These substances are called vitamins. They are essential for various physiological functions in the body, such as metabolism, immune function, and hormone regulation. Vitamins must be obtained through the diet since the body cannot produce them in sufficient amounts.
Golgi complex
The structure responsible for the restriction of movement of large complex substances into the bloodstream is the endothelial cells that line blood vessels. These cells form a barrier known as the blood-brain barrier, which regulates the entry of substances from the bloodstream into the brain and spinal cord to protect the central nervous system.
They're both organisms, right?
Simple substances are combined chemically to form more complex substances by the process of synthesis or combination reactions. In these reactions, two or more reactants, often elements or simpler compounds, react to form a single, more complex product. This process is fundamental in both organic and inorganic chemistry, leading to the creation of a wide variety of compounds. Examples include the formation of water from hydrogen and oxygen gases.
Inorganic substances do not contain carbon-hydrogen bonds, whereas organic substances do. Organic substances are typically derived from living organisms, while inorganic substances are not. Inorganic substances also often lack a complex, carbon-based structure compared to organic substances.
Organic nutrients required in small amounts to maintain growth and normal metabolism are called vitamins. Raw materials that the body can use to assemble some vitamins are provitamins.
Transportation of absorbed substances used to build complex substances in the body is primarily carried out through the bloodstream. Nutrients and other building blocks absorbed in the digestive system are transported via the blood to various tissues where they are utilized in the synthesis of complex substances such as proteins, carbohydrates, and fats. These substances are then incorporated into cells and tissues as needed for growth, repair, and maintenance of the body.
Yes ... but nowhere near as complex as sexual reproduction.

The process that involves the synthesis of complex substances in living things is called biosynthesis. It refers to the production of complex molecules such as proteins, carbohydrates, and lipids from simpler building blocks inside cells. Biosynthesis is essential for growth, repair, and maintenance of living organisms.
Yes ... but nowhere near as complex as sexual reproduction.
Biochemical pathways involve the synthesis of complex substances in living organisms through a series of chemical reactions. These pathways involve enzymes that catalyze the formation of specific molecules needed for growth, maintenance, and function of the organism. Examples include photosynthesis in plants and protein synthesis in animals.
