Actions of Digestive Secretions The breakdown of food into nutrients requires secretions from different organs or glands. Many of these secretions contain enzymes or other compounds that break down one or more of the macronutrients. Five secretions involved in the digestive process are listed below. Choose the macronutrient(s) that each secretion either breaks down or facilitates the breakdown of. Note that some secretions may support the breakdown of more than one macronutrient.

Using the black lines shown in Figure 11.27, name the types of nutrient molecules present at each site that are small enough to be absorbed across the small intestines lining. Figure 11.27 Fill in the blanks for substances that cross the lining of the small intestine.
The digestive system has several important functions. The physiological processes involved in the uitlisation of food happens in a specific order. Explain why digestion needs to happen before absorption. Make use of the macronutrient proteins as an example to explain your answer and to describe its digestion and absorption in detail.
In order for the food to be processed and absorbed in an optimal way, there are several feedback mechanisms. One of the most important starts when the food reaches the small intestine, this is sometimes also called the intestinal phase. Describe what happens if the food that reaches the duodenum contains a lot of fat and a lot of protein Which different signaling pathways (including the signaling substances involved) control the different gastric emptying,hydrochloric sekretion that are affected by the respective stimuli.
Drag and drop each event of nutrient use and storage to the correct state of digestion in which the event occurs. Triglycerides are broken down to fatty acids and glycerol and then converted to glucose Nutrients are taken up from the intestinal lumen Amino acids are Glycogen is broken down to glucose Gluconeogenesis transported into muscle and used to form protein and enter the blood Excess glucose is stored as glycogen Glucose or fatty acids are used for cellular ATP production to meet energy needs Triglycerides are stored in fat cells Glycogenolysis Absorptive and postabsorptive Absorptive Postabsorptive Reset

Describe the process of chemical digestion of our three major macronutrients, carbohydrates, proteins and fats, as one travels down the human digestive tract. Where does chemical digestion begin for each one of these? Where does chemical digestion continue for each one of these three, and where is this process completed? In your description, please include the enzymes involved
It's Halloween and you just ate 27 Reese's peanut butter cups. Describe the ENTIRE process of both chemical AND mechanical digestion from mouth to anus of all of the nutrients in this candy (hint: there are carbs/fats/and proteins present). Your response must include the passing of the candy through all major organs and the role of accessory organs. You must also include key enzymes involved in breaking down each nutrient type AND include keywords like bile, chyme, bolus, etc.
Describe the different ways in which food is chemically digested, including the role of the various components of saliva, gastric juice, pancreatic juice, and bileExplain which hormones control the release of the each of these secretions, the cells used (acinar, parietal cells, etc), and a description of what molecules are being digested and what they are being broken into
Proteasas 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 basic
Describe the location(s) in the digestive tract whereeach of the major types of nutrients is broken down.
The stomach has two types of exocrine cells, chief cell which secrete an inactive form of the protein degesting enzymes pepsinogen, and parietal cells , which secrete hydrochloric acid that activates pepsinogen.Both cell types have an abundance of mitochondria ATP production.The chief cells need energy to synthesise pepsinogen and parietal cells need energy to transport hydrogen ions and chloride ions from the blood into the stomach lumen.Only one of this cell types has an extensive roung endoplasmic and abandant Golgi stacks. Would this be the chief cells or parietal cells?why?
Enzymes that digest dietary proteins in the stomach and intestine are synthesized as proenzymes or zymogens. Which of the following is the proenzyme form of a proteolytic enzyme of the digestive tract? elastase O carboxypeptidase chymotrypsin
