Glycolysis is the series of reactions that produce ATP by converting glucose to pyruvate. The glycolysis pathway occurs in the cytoplasm of all cells and is the first step in aerobic respiration. The reactions convert one six-carbon molecule of glucose to two three-carbon molecules of pyruvate. Each of the two pyruvate molecules that formed in glycolysis has two carbon-carbon bonds. The next two steps of aerobic respiration is the acetyl-CoA formation and the citric acid cycle (Krebs reactions) that break both of these bonds. Energy released at the bond break is captured in electrons carried by NADH and in high-energy phosphate bonds of ATP. All carbon atoms that were once a part of glucose end up in CO 2 , which diffuses out of the cell.

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.
