Understanding Proteins

The video explains the importance of protein in the human body, detailing its structural and functional roles. It describes how proteins are made from amino acids, highlighting the difference between essential and non-essential amino acids. The video also distinguishes between complete and incomplete proteins, emphasizing the need for a varied diet to prevent protein malnutrition, especially for vegans and vegetarians.

What are some of the functions of proteins in the human body?

• They are used to transport oxygen in the blood.

• They are stored as fat in the body.

• They help in the growth and repair of tissues.

• They are the main source of energy.

What happens to proteins when we consume them?

• They are converted into carbohydrates.

• They are broken down into amino acids.

• They are stored in the liver.

• They are excreted as waste.

How many types of amino acids are there?

• 20

• 15

• 10

• 25

What is the difference between essential and non-essential amino acids?

• Non-essential amino acids are not used by the body.

• Essential amino acids must be obtained from the diet.

• Non-essential amino acids must be obtained from the diet.

• Essential amino acids are produced by the body.

Which of the following is a source of complete proteins?

• Broccoli

• Eggs

• Beans

• Rice

What are incomplete proteins?

• Proteins that are not digested by the body.

• Proteins that lack one or more essential amino acids.

• Proteins that are only found in animal products.

• Proteins that contain all essential amino acids.

What can result from a diet consisting only of incomplete proteins?

• Higher energy levels

• Improved digestion

• Protein malnutrition

• Increased muscle mass

Which of the following is NOT a source of complete proteins?

• Milk

• Lentils

• Chicken

• Fish

Why is it important for vegans and vegetarians to consume a variety of protein sources?

• To improve taste

• To ensure they get all essential amino acids

• To reduce fat intake

• To increase calorie intake

What is a key dietary consideration for avoiding protein malnutrition?

• Eating high amounts of carbohydrates

• Eating only animal-based proteins

• Consuming a variety of protein sources

• Avoiding all plant-based proteins
