To explain: The digestion and absorption of three
Introduction: Digestion is a process by which the body fulfills its demand for energy to operate. The conversion of large insoluble molecules into smaller molecules is called digestion. Digestion typically consists of two parts. In one part, the large food chunks are broken down into smaller ones. In the second part, the smaller food particles are digested to the molecular level by the enzymes in chemical digestion Digestion process makes the biomolecules ready for absorption. The movement of digested particles from the lumen of the intestine to the extracellular fluid is called absorption.
To explain: The process of iron absorption.
Introduction: The absorption of minerals usually takes place through active transport. The intestinal absorption of the iron is regulated. The decrease of body concentration of iron gives rise to enhance uptake of the iron at intestine.

- You will only describe how proteins, carbohydrates, and lipids are digested in the body. The goal is to get to a point where there are only amino acids(from proteins), fatty acids (from lipids), and glucose (from starch). Enzymes are only part of chemical digestion. Provide a simple description of Ingestion, Movement, Mechanical digestions, absorption, and elimination related to your food. Lastly describe what glucose, amino acids, and fatty acids will be used once they are absorbed into the bloodstream.arrow_forwardWith the two menus provided, answer the question below: Menu 1: Roasted chicken with mashed potatoes (mostly proteins and carbohydrates) Menu 2: Pasta with alfredo saude and cheese (mostly carbohydrates, dairy products and lipids) Question: Describe the steps in the chemical digestion of the main constituents of your meal (name the enzyme (s) and other secretions involved, and what cells secrete them), all of that from the beginning to the end of digestion.arrow_forwardWhich of the following best describe protein digestion? . Protein digestion is a hydrolytic process regulated by pH changes in the gastro-intestinal track, and hormonal and enzyme releases at various stages of digestion. .. Protein digestion occurs during the gastric phase of digestion starting in the stomach. Protein digestion cleaves peptide bonds releasing peptides, and amino acids Protein digestion is a hydrolytic process involving proteases/ proteinases Protein digestion occurs at the active site of proteases and is effected by the catalytic triads.arrow_forward
- Explain step by step in detailed words what happens during the: Digestion of Carbohydrates Digestion of Proteins Digestion of Lipids/Fats (Give Examples)arrow_forwardcreate a flow chart or diagram to illustrate the digestion and absorption of carbohydrates. The starting carbohydrate molecules are starch, sucrose, lactose, glycogen, and cellulose. What will happen to these carbohydrates once we ingest them? Include the following from your flow chart or diagram: 1) the location or site where the digestion or absorption occurs 2) the enzymes 3) the products generated at each site or locationarrow_forwardProteasas are enzymes that break down proteins. Gastric proteasas are found in the stomach; intestinal proteases are found in the small intestine. Estimate the optimum pH for these two enzymes and identify as acidic or basic: Gastric proteases: pH= ____; acidic or basic Intestinal proteases activity: pH= ____; acidic or basicarrow_forward
- Consider the following nutrients: (water, simple sugar (glucose), amino acid, and fatty acid). Describe where each one is absorbed in the small intestine and which mechanism (active transport, facilitated diffusion, or simple diffusion) drives their movement into the bloodstream. Please be detailed with your explanationarrow_forwardcreate a flow chart or diagram to illustrate the digestion and absorption of proteins. What will happen to the meat once we ingest them? Include the following from your flow chart or diagram: 1) the location or site where the digestion or absorption occurs 2) the enzymes 3) the products generated at each site or locationarrow_forwardWith the two menus provided, answer the question below: Menu 1: Roasted chicken with mashed potatoes (mostly proteins and carbohydrates) Menu 2: Pasta with alfredo saude and cheese (mostly carbohydrates, dairy products and lipids) Question: Clearly indicate where/when nutrient absorption takes place in the digestive tractarrow_forward
- name the protein digesting enzymes.arrow_forwardPut the following terms in their correct order from the simplest to the most complex. Skin cell, Integumentary system , Epithelial tissue, Stem cell , Skin, Organism The stomach produces hydrochloric acid which increases the acidity of the stomach to digest the food. However, the small intestine are not damaged by strongly acidic food coming from the stomach. How does our body avoids damaging the small intestine with this strongly acidic food passes out of the stomach?arrow_forwardWhich of the following is/are TRUE about where the following macromolecules are digested and absorbed by the body? -Carbohydrates are digested by enzymes in the mouth and the small intestine and are absorbed in the small intestine -Three of these answers are correct -Proteins are digested by enzymes in the stomach and the small intestine, and absorbed in the small intestine -Water is absorbed in the stomach and reabsorbed in the large intestine -Two of these answers are correctarrow_forward
