Question
Chapter 4.4, Problem 15WDYL
Summary Introduction
To determine:
How is the resting membrane potential established, and what role does the sodium-potassium channel play in it.
Introduction:
When an electrode is placed on either side of the cell membrane, there is a record of electrical activity. The cell membrane has an electrical charge.
This electrical charge or the voltage across the membrane at rest is called the resting membrane potential.

Please write a 500-word report about the intake of saturated fat, sodium, alcoholic beverages, or added sugar in America. Choose ONE of these and write about what is recommended by the Dietary Guidelines for Americans (guideline #4) and why Americans exceed the intake of that nutrient. Explain what we could do as a society and/or individuals to reduce our intake of your chosen nutrient.
Write a 500-word report indicating how you can change the quantity or quality of TWO nutrients where your intake was LOWER than what is recommended by the Dietary Guidelines for Americans and/or the DRIs. Indicate how the lack of the nutrient may affect your health.
For full credit, all of the following points must be addressed and elaborated on in more detail for each nutrient:
The name of the nutrient
At least 2 main functions of the nutrient (example: “Vitamin D regulates calcium levels in the blood and calcification of bones.”)
Your percent intake compared to the RDA/DRI (example “I consumed 50% of the RDA for vitamin D”)
Indicate why your intake was below the recommendations (example: “I only had one serving of dairy products and that was why I was below the recommendations for vitamin D”)
How would you change your dietary pattern to meet the recommendations? – be sure to list specific foods (example: “I would add a yogurt and a glass of milk to each day in order to increase my…

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.arrow_forward
- 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.arrow_forwardWhen taking vitamins and vitamin-mineral supplements, how can one be sure they are getting what they are taking?arrow_forwardHow many milligrams of zinc did you consume on average per day over the 3 days?
