Micheal Phelps (Olympic swimmer) has a caloric intake of 12,000 calories a day, most of which comes from a diet of pizza, fried food, and milkshakes. What is the best argument to support this type of diet for Micheal Phelps compared to a body builder?

• Swimmers need to consume a lot more carbohydrates to have a source of quick energy whereas body builders need to consume more proteins to help in muscle formation

• Swimmers need to consume a lot of protein to have prolonged energy whereas body builders need to consume more carbohydrates to help in muscle formation

• High caloric intake is suitable for all active individuals because the more food you consume, the more of each macromolecules you consume.

• Swimmers need to consume a lot of lipids to have prolonged energy whereas body builders need to consume more nucleic acids to help in muscle formation

Which of the following are the building blocks of polymers?

• Proteins

• monomers

• elements

The elements that make up proteins are

• C, H

• C, H, O

A professional body builder eats lots of chips and drinks lots of soda as his snack on a daily basis. Which argument presents the best alternative supported by the correct evidence?

• The body builder should not swap his chips and soda because body builders need lots of energy to lift the heavy weight.

• The body builder should swap his chips and soda for a doughnut because the donut is a complex carbohydrate which will help him repair his muscles better than chips and soda

• The body builder should swap his chips and soda for a protein shake because proteins will help provide the most energy for them while the carbohydrates in the chips and soda help rebuild muscles

• The body builder should swap his chips and soda for a protein shake because proteins will help the muscles repair themselves after his workout while the chips and soda only provide quick energy
