Understanding Proteins

What are the primary functions of proteins in the body?

• Generating electrical signals in neurons

• The primary functions of proteins in the body include catalyzing reactions, providing structure, transporting molecules, regulating processes, and supporting immune function.

• Storing energy for long-term use

• Producing hormones exclusively

How do proteins contribute to muscle growth and repair?

• Proteins are primarily used for energy production during exercise.

• Proteins are not involved in muscle repair or growth.

• Proteins contribute to muscle growth and repair by providing amino acids necessary for repairing muscle fibers and synthesizing new muscle tissue.

• Proteins help in the digestion of carbohydrates and fats.

What role do enzymes, which are proteins, play in the body?

• Enzymes provide structural support to cells.

• Enzymes store genetic information in the body.

• Enzymes act as hormones to regulate body temperature.

• Enzymes speed up chemical reactions in the body, aiding in digestion, metabolism, and other vital processes.

Name three dietary sources of complete proteins.

• tofu

• peanut butter

• eggs, quinoa, chicken

• spinach

What is the difference between complete and incomplete proteins?

• Complete proteins are higher in calories than incomplete proteins.

• Complete proteins have all essential amino acids; incomplete proteins lack one or more.

• Incomplete proteins can be converted into complete proteins through cooking.

• Complete proteins are only found in animal sources; incomplete proteins are only in plants.

How do proteins help in the immune response?

• Proteins directly destroy pathogens without any other assistance.

• Proteins provide energy for immune cells.

• Proteins help in the immune response by acting as antibodies, signaling molecules, and components of the complement system.

• Proteins act as a source of vitamins for the immune system.

List two plant-based sources of protein.

• Lentils, Chickpeas

• Almonds

• Quinoa

• Tofu

Why is protein important for hormone production?

• Amino acids are not necessary for hormone synthesis.

• Hormones are produced solely from carbohydrates.

• Proteins are not involved in hormone production.

• Protein is important for hormone production because it provides the amino acids necessary for synthesizing hormones.

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

• 40 to 60 grams of protein per day

• 100 to 120 grams of protein per day

• 68 to 90 grams of protein per day

• 30 to 50 grams of protein per day

How can a lack of protein in the diet affect health?

• Increased energy levels and improved mood

• Enhanced muscle growth and strength

• Better digestion and nutrient absorption

• A lack of protein can lead to muscle loss, weakened immunity, and various health issues.
