Carbohydrates
What biomolecule is the main source of quick energy for the body?
Carbohydrates
What biomolecule includes fats and oils?
Lipids
What biomolecule helps build muscles and tissues?
Proteins
Give one example of a genetic trait.
Eye color, height potential, hair color
Which biomolecule provides long-term energy storage?
Lipids
What are two examples of foods that are high in carbohydrates?
Bread, pasta, rice, fruits, cereal (any two)
What is one function of lipids in the body?
Long-term energy storage, insulation, or cell membranes
Name one food that is high in protein.
Meat, eggs, beans, nuts, dairy
Name one environmental factor that affects growth
Nutrition, sleep, exercise, illness
Which biomolecule is most important for repairing muscles after exercise?
Proteins
What is the main function of carbohydrates in living organisms?
Provide energy
Why do animals store energy as lipids instead of carbohydrates?
Lipids store more energy for long periods
What are proteins broken down into during digestion?
Amino acids
Can genetics alone determine how tall a person will grow? Why or why not?
No, environment also plays a role
Which biomolecule would an athlete need most for quick energy?
Carbohydrates
What type of sugar is broken down during digestion to give cells energy?
Glucose
What part of the cell is mainly made of lipids?
Cell membrane
Why are proteins important for growth and repair?
They help build and fix body tissues
How do exercise and diet work together to support healthy growth?
Exercise strengthens the body and good nutrition provides energy and building materials
Which has a bigger effect on growth: genetics or environment? Explain.
Both—genetics sets limits, environment influences outcomes
How would an athlete feel during a game if they did not eat enough carbohydrates beforehand, and why?
They would feel tired or weak because carbohydrates provide quick energy.
Why are lipids better than carbohydrates for long-term energy storage in the body?
Lipids store more energy and last longer than carbohydrates.
What might happen to a person’s growth or muscle repair if they do not eat enough protein?
Poor growth, weak muscles, or slower healing.
If two people eat the same healthy diet but grow to different heights, what factor most likely explains the difference?
Genetic factors.
Explain how both genetics and environment work together to affect a person’s growth.
Genetics set the potential for growth, and environmental factors like diet, sleep, and exercise affect how much of that potential is reached.
