Answer:
1. The correct answer is B. Anaerobic. Anaerobic energy system is the body's energy system that does not require oxygen. This energy system is used during short bursts of intense physical activity, such as sprinting or weightlifting. It provides quick energy but is not sustainable for long periods.
2. The three types of energy systems that the body utilizes during physical activity participation are: A. ATP-CP (Adenosine Triphosphate-Creatine Phosphate), Anaerobic Glycolytic, and Aerobic.
- ATP-CP system provides immediate energy for short bursts of high-intensity activity, lasting about 10 seconds.
- Anaerobic Glycolytic system provides energy for activities lasting from 10 seconds to 2 minutes. It uses glucose stored in the muscles as glycogen.
- Aerobic system is used for longer-duration activities, such as jogging or cycling. It utilizes oxygen to convert stored glycogen or fat into energy.
3. The basic requirement for all body processes is B. Energy. Energy is needed for growth and development, transportation of substances between cells, tissue repair, and muscle contraction. It is obtained from the food we eat and is stored in the form of ATP (Adenosine Triphosphate).
4. The basic form of energy used by cells is D. Adenosine triphosphate (ATP). ATP is often referred to as the "energy currency" of cells because it provides energy for cellular processes. When ATP is broken down, energy is released and used by the cells.
5. The energy system used when the intensity of the activity is low to moderate is A. Aerobic. Aerobic energy system relies on oxygen to convert stored glycogen or fat into energy. It is used during activities such as brisk walking or swimming at a moderate pace.
6. If the duration of the activity is 10 seconds to 2 minutes, the energy system used is B. Anaerobic Glycolytic. This energy system utilizes stored glycogen in the muscles and provides energy for activities like a 400-meter sprint or a set of weightlifting.
7. The activity that does NOT primarily use the ATP-CP energy system is B. 2 km. walk. The ATP-CP system is utilized for short bursts of high-intensity activities, such as a 40-meter sprint or explosive movements. Walking a longer distance primarily relies on the aerobic energy system.
8. The energy system used if the duration of the activity is less than 10 seconds is A. ATP-CP. The ATP-CP system provides immediate energy for short bursts of high-intensity activities, lasting up to about 10 seconds. Examples include a quick sprint or a vertical jump.
9. The energy system that produces a burning sensation and lactic acid during physical activities is A. Anaerobic Lactic. This energy system, also known as the lactic acid system or glycolytic system, is used during intense activities when the aerobic system cannot supply enough oxygen. It produces energy quickly but also results in the buildup of lactic acid, causing the burning sensation.
10. In a 5-kilometer fun run, you will primarily use A. Aerobic energy system. Since the duration of the activity is relatively long, your body will rely on the aerobic system to convert stored glycogen or fat into energy. This system can sustain energy production for endurance activities like running longer distances.
