Food digested in the stomach passes through the intestines so that the blood vessels can absorb essential nutrients for the functioning and growth of the body. What is this process known as?
Transmission
Assimilation
Transfusion
Integration
Assimilation
Assimilation is the biological process where absorbed nutrients are transported via the blood to various body cells and converted into living protoplasm or used for energy and repair. Once nutrients cross the intestinal wall into the bloodstream (absorption), the body 'assimilates' them to build tissues or fuel metabolic pathways.

Once nutrients cross the intestinal wall into the bloodstream (absorption), the body 'assimilates' them to build tissues or fuel metabolic pathways.
Think of it like buying building supplies at a store (absorption); taking them to the construction site (transport via blood); and finally using them to build the actual house (assimilation).
A-A-A: Absorption (taking in), Assimilation (adding to the body), Allocation (using it).
C6тАЛH12тАЛO6тАЛ+6O2тАЛтЖТ6CO2тАЛ+6H2тАЛO+ATP тАФ cellular respiration for energy production during assimilation
The process involves the movement of absorbed monomers like amino acids, glucose, and fatty acids through the circulatory system to target organs. Inside cells, these molecules undergo metabolic processes such as C6тАЛH12тАЛO6тАЛ+6O2тАЛтЖТ6CO2тАЛ+6H2тАЛO+Energy┬а(ATP) to provide biological fuel. Proteins are synthesized from amino acids to repair damaged cells and facilitate structural growth, governed by DNA-directed protein synthesis.
Assimilation occurs after absorption in the small intestine.
It converts food into complex organic components of the body (e.g., protoplasm).
It is a vital step in metabolism for both catabolic (energy releasing) and anabolic (building up) pathways.
Ensures continuous supply of energy for homeostatic maintenance.
Facilitates growth and tissue regeneration.
Formation of new cells (mitosis).
Energy production for muscle contraction.
Absorption is the uptake of nutrients; Assimilation is the utilization of those nutrients.
Transmission refers to signals, Transfusion refers to blood transfer, and Integration refers to functional unification, none of which describe nutritional utilization.
B is correct тАФ Assimilation refers to the utilization of absorbed nutrients by the body cells to build protoplasm or produce energy.
In competitive exams, always distinguish between absorption (the act of crossing the intestinal membrane) and assimilation (the act of the cells incorporating these nutrients for functional use).
