Final answer:
True. Changes in temperature and acidity shift the oxyhemoglobin dissociation curve to the right, causing greater delivery of oxygen to muscle tissue during exercise.
Step-by-step explanation:
True. Changes in temperature and acidity can cause the oxyhemoglobin dissociation curve to shift to the right, resulting in greater delivery of oxygen to muscle tissue during exercise.
When temperature increases, such as during exercise, the affinity of hemoglobin for oxygen decreases. This causes oxygen to dissociate from hemoglobin, making more oxygen available to the muscle tissue.
Similarly, when acidity increases (as indicated by a decrease in pH), the affinity of hemoglobin for oxygen also decreases, causing the dissociation curve to shift to the right and facilitating oxygen delivery to the muscle tissue.
