Using carbon as an example, describe the structure of the atom. Include a statement about what makes carbon such a versatile atom. Define chemical bond and explain how and why atoms form ionic bonds. How and why do they form covalent bonds? What is a hydrogen bond and why do water molecules participate in hydrogen bonds? Describe two of water\'s extraordinary properties that can be attributed to hydrogen bonds. Summarize the functions of the four classes of biological macromolecules in our bodies. Before a large race or endurance sports event, many athletes \"carbo-load.\" What is carbo-loading and how does it work? What is the difference between saturated and unsaturated fats? Which ones are healthier and why? Discuss the structure of proteins. Why is it essential that the chemistry of their surrounding environment remain constant? What is an enzyme and how do they work?

Solution

Answer:

5) Carbohydrate loading which is also referred to as carb-loading or carbo-loading is a diet stratagy followed by some endurance athletes prior to competition that increases the amount of glycogen, or stored glucose, in muscles. Hence it is meant to store extra glycogen that muscles can use once the normal stores are used up. Carbohydrate loading resuts in less fatigue and greater endurance potential. During exercise, muscles and liver use glycogen, or stored glucose, it is the main source of energy used in intense endurance events. Liver converts excess dietary carbohydrates into complex chains of glucose called glycogen. Glycogen is stored in liver and muscle cells and is a secondary source of energy used for exercise. So loading up on carbs can mean a big energy boost. Carbohydrate loading is generally recommended for endurance events that lasts 90 minutes or more, since that\'s when the body starts running low on glycogen.
