Describe how a piece of steak in your mouth can become an amino acid in your blood that your cells can use to build muscle tissue, insulin, or other hormones. Describe how the body may make use of or store energy-yielding nutrients in the following two situations: a. A person has eaten a high-carbohydrate meal and is now running a marathon. b. A person has eaten a high-carbohydrate meal and is now playing video games for several days.

Solution

1. Steak is meat which is high in protein and protein is an amino acid. Protein builds and repairs muscle tissues.
digestion breaks up the proteins into their constituent parts (amino acids), which are then used in the body to build more proteins.

2. (A)

Carbohydrates are sugar-based molecules, and the body can use it to produce glucose. Glucose will become stored within the liver and muscle as glycogen.These are molecules for long-time energy storage that may be used when needed. But experienced runners know it is poor practice to ingest large amount of glucose before running because excessive blood-glucose level would cause the secretion of insulin, which would stimulate the synthesis of glycogen and triacylglycerols. A high insulin level would hinder the mobilization of fuel reserves during marathon.
High consumption of sugar forces pancreas to work beyond regulation, leading to type-2 diabetes.It additionally lowers stages of HDL (exact) ldl cholesterol, while growing triglycerides. Both are causes for heart attack.
More and more runners are struggling with health problems, like hypertension and diabetes, due to the high quantities of sugar they are eating.

(B) Heart rate, systolic and diastolic blood pressures, sympathetic tone, and mental workload were significantly higher during the video game play condition than during the resting condition . Although energy expenditure was significantly higher during video game play than during rest. The increase in food intake associated with video game play was observed without increased sensations of hunger and was not compensated for during the rest of the day. Finally, the profiles of glucose, insulin, cortisol, and ghrelin did not suggest an up-regulation of appetite during the video game play condition.
