All of these are the components of the catabolic pathway or using the nutrients to provide energy from it. The breakdown of food molecules begins in the mouth and continues to the small intestine. The nutrients are absorbed through the wall of the small intestine which. The surface of the intestine wall is specially modified (contains a huge number of hair-like structures-microvilli) which increase nutrient absorption. (more area for nutrients to be absorbed). The digestive tract is lined with mucosa which consists of simple columnar epithelial cells. Monomer subunits of the food, like glucose are than absorbed and diffused down a concentration gradient into capillary blood. Glucose is converted into pyruvate molecules through the process of glycolysis. Catabolism ends in the major energy-converting organelle, the mitochondrion, where the ATP is produced.
Answer:
Embryo cell or totipotent cell
Explanation:
All organisms during their embryonic stage also known as totipotent cells are composed of cells that are identical in structure and function. These cells can differentiate at a later stage and have the potential to become any cell i.e heart cell, eye cell etc. Embryo is thus just a mass of unspecialized cell which undergo differentiation to then convert into pluripotent and form tissues and hence the organ.
