Question

question 1 - 7
after a workout, the muscles in a basketball players legs are very sore. which of the following statements best explains why the basketball player experiences this muscle soreness after a workout?
there is an increase in the amount of water being delivered to the muscle cells during the process of anaerobic respiration.
there is an increase in the amount of oxygen being delivered to the muscle cells during the process of aerobic respiration.
there is an increase in the amount of glucose being produced in the muscle cells during the process of aerobic respiration.
there is an increase in the amount of lactic acid being produced in the muscle cells during the process of anaerobic respiration.

Explanation:

Step1: Recall anaerobic respiration in muscle cells

During intense exercise (like a basketball player's workout), when oxygen supply is limited, muscle cells undergo anaerobic respiration.

Step2: Know the product of anaerobic respiration in muscle cells

The formula for anaerobic respiration in muscle cells is \(C_6H_{12}O_6
ightarrow 2C_3H_6O_3+ \text{energy}\) (where \(C_3H_6O_3\) is lactic acid). Lactic acid accumulation causes muscle soreness.

Step3: Analyze each option

• Option 1: Water is not the cause of muscle soreness from anaerobic respiration.
• Option 2: Aerobic respiration occurs when oxygen is sufficient. During a strenuous workout (leading to soreness), anaerobic respiration is more prominent.
• Option 3: Glucose is consumed in respiration (both aerobic and anaerobic), not produced in muscle cells during these processes in the context of causing soreness.
• Option 4: Lactic acid is produced in anaerobic respiration in muscle cells and its accumulation causes soreness.

Answer:

There is an increase in the amount of lactic acid being produced in the muscle cells during the process of anaerobic respiration.
