WebDuring exercise the a- VO2 difference increases up to 3 times the resting value. Bohr Effect Conditions Increased PCO2 Increased temperature Increased 2,3-DPG Decreased pH ** Cause a shift to the right of the oxyhemoglobin dissociation curve Myoglobin "The Muscle’s O2 Store" -an iron-containing globular protein in skeletal and cardiac muscle Web• Oxygen diffusion rate increases from rest to exercise • Exercising muscle requires more oxygen for metabolism; when venous oxygen is depleted, oxygen exchange at the alveoli is facilitated due to an increased pressure gradient • pressure gradient for carbon dioxide exchange: less than for oxygen exchange, but carbon dioxide’s membrane solubility is … how many atomic mass are in carbon
How does exercise affect pO2 in the muscle cell? - Answers
WebFeb 15, 2024 · Increased CO production: CO2 is a by-product of oxidative metabolism, and high CO2 production may occur due to fever, exercise, hyperalimentation, sepsis, and thyrotoxicosis. High C2Oproduction becomes pathologic if the compensatory increase in minute ventilation mechanism fails. [16] Go to: History and Physical WebJul 30, 2024 · Interestingly, exercise does not cause hyperpnea as one might think. Muscles that perform work during exercise do increase their demand for oxygen, stimulating an increase in ventilation. However, hyperpnea during exercise appears to occur before a drop in oxygen levels within the muscles can occur.
