Which part of the digestive tract facilitates movement of amino acids from the gastrointestinal system into the bloodstream?
Stomach

Protein absorption happens in the small intestine, which contains microvilli. These are small, finger-like
structures that increase the absorptive surface area of the small intestine. This allows for maximum
absorption of amino acids and other nutrients.
The stomach contributes both mechanical and chemical digestion of proteins. The liver also plays an
important role in the metabolism of proteins: liver cells change amino acids in foods so that they can be
used to produce energy or make carbohydrates or fats. A toxic substance called ammonia is a by-product
of this process. The large intestine carries waste to the rectum.

/ Your response is correct!
Catabolism is the process of breaking protein into amino acids that can be used by the body (think
“catabolism cuts”). Anabolism is the process used by the cells to create specific proteins from those amino
acids to have specific functions.
Kabbalism is a school of thought in Jewish mysticism and more relevant to an individual’s culture and
spiritual practices than nutrition. Agnosticism is the view that the existence of God, of the divine, or the
supernatural is unknown or unknowable and is also more relevant to an individual’s culture and spiritual
practices than nutrition. Segmentation involves the contraction and relaxation of the smooth muscle in the
intestines which moves food along the digestive tract.
, Types of Proteins
When providing nutritional education for a group of grade-school aged children, the teacher plans an activity that sorts proteins by their
essential amino acid status. Select each food source of protein for the corresponding type of protein category.

Complete proteins contain all the essential amino acids. Complete proteins are mainly found in animal
products such as milk, eggs, cheese, and hamburgers. Tofu, a plant-based protein made using soybeans, is
also a complete protein.
Most plant-based proteins are incomplete, including corn, quinoa, and legumes. These do not contain all
the essential amino acids. However, individuals who eat a primarily plant-based diet can obtain all the
essential amino acids by eating various foods throughout the day.
Protein Absorption
Which factors increase or decrease the absorption of amino acids? Drag each item to the correct category.
Increase Absorption Decrease Absorption
Factors Vitamin B6 Insulin Fewer pancreatic enzymes Lower gastric acidity
Review Feedback i j
/ Your response is correct!
Amino acid absorption from the small intestine is promoted by vitamin B6. Insulin within the body helps
cells absorb amino acids.
Protein absorption can be decreased when the stomach secretes less hydrochloric acid and in the absence
of pancreatic enzymes.
