BPE 102 1ST QUIZ

What is the primary function of homeostasis during physical activity?

• To increase body temperature indefinitely

• To prevent muscle growth and energy production

• To maintain a stable internal environment despite external changes

• To stop sweating and conserve body fluids

Which of the following is an example of aerobic metabolism?

• A long-distance runner completing a marathon

• A sprinter running a 100-meter dash

• A weightlifter performing a deadlift

• A gymnast performing a vault jump

How does the body regulate temperature during intense exercise?

• By decreasing blood circulation to the skin

• By stopping oxygen supply to the muscles

• By lowering heart rate to conserve energy

• By increasing sweat production to cool down the body

What happens when oxygen supply is insufficient during high-intensity exercise?

• The body stops producing ATP

• The body switches to anaerobic metabolism, leading to lactic acid buildup

• Muscles stop contracting and relax completely

• The body immediately starts using only fats for energy

Why is hydration important for homeostasis during exercise?

• It prevents sweating and overheating

• It eliminates the need for oxygen during metabolism

• It helps regulate body temperature and maintain blood volume

• It stops the body from using stored energy

The body's ability to maintain a stable internal environment despite external changes is called __________.

The process of breaking down food and converting it into energy is known as __________.

The stored form of glucose in the muscles and liver, used for energy during exercise, is called __________.

The two types of metabolism are __________ and __________ metabolism.

During high-intensity exercise, when oxygen supply is low, the body produces __________, which can cause muscle fatigue.
