b. They increase the transport of fatty acids into the mitochondria.
c. They increase delivery of oxygen to the muscle.
d. They eliminate free radicals.
They increase the amount of creatine phosphate in the muscle best describes how creatine supplements enhance performance.
Correct option is A. They increase the amount of creatine phosphate in the muscle.
Creatine is a naturally occurring compound in the body that assists in the production of Adenosine Triphosphate (ATP), a key energy source in muscle contraction. Supplementation with creatine has been found to increase the amount of creatine phosphate in the muscle, which leads to improved energy production.
This can result in an increase in muscle size and strength, and better performance during high-intensity activities. Additionally, creatine increases the transport of fatty acids into the mitochondria, which can be used to create even more ATP and energy. It has also been found that creatine can increase delivery of oxygen to the muscle, allowing for a higher intensity and longer duration of training.
Lastly, creatine has antioxidant effects, which allows it to eliminate free radicals to protect muscle cells and further improve muscle health. Therefore, supplementing with creatine can significantly benefit performance by increasing energy production, enhancing fat burning and increasing oxygen delivery to the muscle.

why is a measure of serum lactate in trauma patients
Measuring serum lactate levels in trauma patients is important because it provides valuable information about tissue perfusion and the adequacy of oxygen delivery to the body's tissues.
In the context of trauma, an elevated lactate level is often an indicator of inadequate tissue oxygenation and can be suggestive of hypoperfusion or shock.
During a traumatic event, the body's oxygen demand increases due to tissue injury and the stress response. If the oxygen supply to the tissues is insufficient to meet this increased demand, anaerobic metabolism may occur, leading to the production of lactate as a byproduct. Elevated lactate levels can indicate tissue hypoxia and can be a sign of inadequate blood flow to organs and tissues.
By measuring serum lactate levels, healthcare providers can assess the severity of tissue hypoxia and the effectiveness of resuscitation efforts. Serial lactate measurements can also be used to monitor the response to treatment and guide further management decisions. A decreasing lactate level over time is generally indicative of improving tissue perfusion, while persistently elevated levels may indicate ongoing hypoperfusion or other underlying issues.
In summary, measuring serum lactate levels in trauma patients helps evaluate tissue perfusion, assess the adequacy of oxygen delivery, and guide resuscitation efforts. It is a valuable tool in the early recognition and management of shock and can assist healthcare providers in optimizing patient care and outcomes.
