Question

Chapter 5, Problem 1SQ

Summary Introduction

Concept introduction: The cells are the structural and fundamental units of an organism that require energy for growth, development, reproduction, and defense.

Expert Solution & Answer

Answer to Problem 1SQ

Correct answer: The cells obey the laws of thermodynamics. Hence, option c. is the correct answer.

Explanation of Solution

Reasons for the correct statement:

The first law of thermodynamics says that energy cannot be created or destroyed; it only transfers from one form to another form. In a cell, the chemical energy is transferred into mechanical energy and then heat energy. In a living system such as in a cell, the second law of thermodynamic states that the capture and storage or use of energy is never 100 percent by the living cells. The energy is lost as a disordered and metabolic heat. Hence, option c. is the correct answer.

Reasons for the incorrect statements:

Option a. is given as “cells can produce their own energy from nothing”. Cells cannot produce energy on their own from nothing. They use living and nonliving components of the environment to obtain their own energy. Hence, option a. is incorrect.

Option b. is given as “cells use energy only to generate heat and move molecules around”. Cells use energy to carry out several metabolic pathways in the body. Hence, option b. is incorrect.

Option d. is given as “most animals obtain energy from minerals to fuel their metabolic needs”. Minerals cannot provide energy directly. Hence, option d. is incorrect.

Hence, option a., b., and d. are incorrect.

Conclusion

The cells obey the laws of thermodynamics.

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.
