Question

1. what effect can combining different incomplete proteins have?

it can create a complete protein source.
it increases carbohydrate content.
it decreases their nutritional value.
it makes them indigestible.

1. fiber helps in:

building muscles
storing energy
converting glucose to glycogen
moving waste through the digestive system

1. what negative effect do saturated fats have on blood?

they thin it
they thicken it
they clean it
they color it

Explanation:

• Question 7: Incomplete proteins lack one or more essential amino acids. By combining different incomplete proteins (e.g., grains and legumes), all essential amino acids can be provided, creating a complete protein source. Carbohydrate content is not increased (proteins are a separate macronutrient), nutritional value is increased (not decreased), and they do not become indigestible.
• Question 8: Fiber is indigestible. It helps in moving waste through the digestive system (e.g., adding bulk to feces). Building muscles is a function of protein, storing energy is mainly for fats and carbohydrates (glycogen for short - term storage in the case of carbohydrates), and converting glucose to glycogen is a liver function related to carbohydrate metabolism.
• Question 9: Saturated fats can increase low - density lipoprotein (LDL) cholesterol levels. High LDL levels can lead to the buildup of plaque in arteries, which in a sense "thickens" the blood (more accurately, it can lead to a state where blood flow is more restricted due to arterial narrowing). They do not thin, clean, or color the blood.

Answer:

1. It can create a complete protein source.
2. Moving waste through the digestive system.
3. They thicken it.
