Question

1. what is fiber?

an indigestible complex carbohydrate.
a type of protein.
a simple sugar.
a digestible fat.

1. which foods are good sources of fiber?

red meats
seafood
fruits and whole grains
dairy products

1. what could happen if you consume too much protein without sufficient exercise?

protein will enhance brain function.
excess protein will be stored as body fat.
protein will convert directly to sugar.
it will increase fiber in the body.

Explanation:

• Question 6: Fiber is an indigestible complex carbohydrate. Proteins are different macromolecules (chains of amino acids), simple sugars are monosaccharides (like glucose), and fats are lipid - based molecules.
• Question 7: Fruits and whole grains are rich in dietary fiber. Red meats are high in protein and fat, seafood is a good source of protein and some minerals, and dairy products are mainly sources of protein (casein, whey) and calcium.
• Question 8: When there is excess protein intake without sufficient exercise, the body cannot store protein in its original form. Excess amino acids from protein are metabolized, and the carbon skeletons can be used to synthesize fat, so excess protein will be stored as body fat. Protein does not directly convert to sugar (gluconeogenesis from protein is a more complex process and not a direct conversion in the context of this question), and it does not increase fiber (which is a carbohydrate - based component).

Answer:

1. An indigestible complex carbohydrate.
2. Fruits and whole grains.
3. Excess protein will be stored as body fat.
