Fats burn in the flame of carbohydrates" refers to the fact that when glycogen gets depleted during prolonged high-intensity exercise, fat oxidation will subsequently be reduced. Group of answer choices: True False An enzyme that works in the stomach will have a lower optimal pH compared to the optimal pH for enzymes that work in other areas of the body. Group of answer choices: True False A shift from fat to carbohydrate usage with increasing exercise intensity can occur because lactate stimulates Î± glycerol phosphate to convert 3 fatty acids into stored triglycerides, thus promoting carbohydrate usage. Group of answer choices: True False Research indicates that genetics plays a large role in an individual's VO2 max (i.e., inherited from their parents). Group of answer choices: True False Short-term, high-intensity activities will have a greater contribution from anaerobic energy systems than aerobic energy systems. Group of answer choices: True False
