Question
One of the consequences of treppe is the release of heat. Describe the effect that this has.Multiple choice question.The increase in temperature increases the solubility of oxygen into the muscle.The increase in temperature increase motor unit size.The increase in temperature increases the number of receptors in the sarcolemma.The heat released increases the activity of enzymes.
Solution
The correct answer is "The heat released increases the activity of enzymes."
Here's why: Treppe, also known as the staircase phenomenon, is a condition where the muscle contraction becomes more forceful with each subsequent stimulus, due to an increase in calcium ions in the sarcoplasm. One of the byproducts of this increased muscle activity is the release of heat.
This heat can have several effects on the body, but in the context of this question, the most relevant effect is on enzyme activity. Enzymes are proteins that catalyze (speed up) chemical reactions in the body, and many of them are sensitive to temperature. As the temperature increases, these enzymes can become more active, leading to an increase in the rate of the reactions they catalyze.
This is why the correct answer is "The heat released increases the activity of enzymes." The other options are not directly related to the effects of heat on the body. For example, while temperature can affect the solubility of gases like oxygen, this is not a direct consequence of treppe. Similarly, temperature does not directly affect motor unit size or the number of receptors in the sarcolemma.

Why does muscle activity affect the temperature of the body?Multiple ChoiceThe rate of chemical reactions increases in muscle fibers during contraction, so the rate of heat production also increases.Muscle contraction generates pyrogens, which reset the body's internal thermostat to a higher temperature.Muscle activity directs more warm blood to the muscles away from the central core, causing a cooling effect on your internal organs.Increased muscle activity causes a rise in adipose stores, which increases the insulation value of the body.
