Proteins Quiz

What are proteins made up of?

• Amino acids

• Lipids

• Carbohydrates

• Nucleic acids

How many essential amino acids are there?

• 9

• 3

• 12

• 5

What is the primary function of proteins in the body?

• Transport of oxygen in the blood

• Regulation of body temperature

• Energy storage in cells

• Building blocks for tissues, enzymes for chemical reactions, and antibodies for immune response

Which foods are good sources of protein?

• Ice cream, cookies, cake

• Potatoes, carrots, broccoli

• Pasta, rice, bread

• Chicken, turkey, fish, beef, tofu, lentils, beans, Greek yogurt

What is the difference between complete and incomplete proteins?

• Complete proteins lack essential amino acids, while incomplete proteins contain all essential amino acids.

• Complete proteins contain all essential amino acids, while incomplete proteins lack one or more essential amino acids.

• Complete proteins are lower in protein content than incomplete proteins.

• Complete proteins are plant-based, while incomplete proteins are animal-based.

What is the role of enzymes in protein digestion?

• Enzymes convert proteins into carbohydrates

• Enzymes have no role in protein digestion

• Enzymes break down proteins into smaller peptides and amino acids for absorption.

• Enzymes build up proteins instead of breaking them down

What are the four levels of protein structure?

• Primary, Secondary, Quinary, Quaternary

• Primary, Secondary, Tertiary, Quintenary

• Primary, Secondary, Tertiary, Quinary

• Primary, Secondary, Tertiary, Quaternary

How does denaturation affect protein structure?

• Denaturation enhances the stability of protein structure by strengthening covalent bonds

• Denaturation disrupts the protein structure by breaking non-covalent bonds, leading to loss of biological activity.

• Denaturation has no effect on protein structure

• Denaturation leads to increased biological activity of proteins

What is the recommended daily intake of protein for an average adult?

• 1.5 grams per kilogram of body weight

• 10 grams per kilogram of body weight

• 0.8 grams per kilogram of body weight

• 2 grams per kilogram of body weight

What are the potential consequences of protein deficiency?

• Rapid wound healing

• Enhanced immune system

• Muscle loss, weakened immune system, slow wound healing, fatigue, hair loss, impaired mental function

• Increased muscle mass
