The Lactic Acid System

a. supplies energy needed to walk or cycle continuously
b. provides energy to pitch a baseball
c. creates energy needed to pass another 5k participant with a burst on energy.
d. none of these

I just know that "The lactic acid system is capable of releasing energy to resynthesise ATP without the involvement of oxygen and is called anaerobic glycolysis."

The Lactic Acid System refers to one of the energy systems in the human body that helps produce energy during certain types of physical activities. It primarily utilizes carbohydrates as fuel and operates anaerobically, meaning without the presence of oxygen.

Now, let's evaluate each statement to determine if it accurately describes the role of the Lactic Acid System:

a. Supplies energy needed to walk or cycle continuously: This statement is incorrect. Walking or cycling continuously at a moderate pace predominantly relies on the aerobic energy system, which utilizes oxygen for energy production. The Lactic Acid System is not the primary energy source for these types of activities.

b. Provides energy to pitch a baseball: This statement is partially correct. The Lactic Acid System does come into play during activities that require short bursts of high-intensity effort, such as pitching a baseball. However, it is important to note that pitching a baseball also involves other energy systems, such as the ATP-PCr system.

c. Creates energy needed to pass another 5k participant with a burst of energy: This statement is correct. When you need to perform a quick burst of high-intensity effort, such as sprinting to pass another participant in a 5k race, the Lactic Acid System is activated. It helps generate energy rapidly to meet the increased demand.

d. None of these: This statement is partially correct. While option d states that none of the provided choices correctly describe the role of the Lactic Acid System, it is important to note that option c does accurately describe a situation where the Lactic Acid System is involved.

Therefore, the correct answer would be option c, as it accurately describes a scenario that involves the activation of the Lactic Acid System.
