Summary Introduction

To explain: The digestion and absorption of three biomolecules including location, enzymes, and the mechanisms in tabular form.

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.

Summary Introduction

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.

Older adults have unique challenges in terms of their nutrient needs and physiological changes. Some changes may make it difficult to consume a healthful diet, so it is important to identify strategies to help overcome these obstacles. From the list below, choose all the correct statements about changes in older adults. Select all that apply.   Poor vision can make it difficult for older adults to get to a supermarket, and to prepare meals. With age, taste and visual perception decline. As people age, salivary production increases. In older adults with dysphagia, foods like creamy soups, applesauce, and yogurt are usually well tolerated. Lean body mass increases in older adults.
When physical activity increases, energy requirements increase also. Depending on the type, intensity, and duration of physical activity, the body’s requirements for certain macronutrients may change as well. From the list below, choose all the correct statements about the effects of increased physical activity or athletic training. Select all that apply. An athlete who weighs 70 kg (154 lb) should consume 420 to 700 g of carbohydrate per day. How much additional energy an athlete needs depends on the specific activity the athlete engages in and the frequency of the activity. Those participating in vigorous exercise should restrict their fat intake to less than 15%% of total energy intake. Athletes who are following energy-restricted diets are at risk for consuming insufficient protein. The recommendation to limit saturated fat intake to less than 10%% of total energy intake does not apply to athletes or those who regularly engage in vigorous physical activity.
When taking vitamins and vitamin-mineral supplements, how can one be sure they are getting what they are taking?
