Answer:
Myoglobin
Explanation:
-Myoglobin is an oxygen-binding molecule found in muscles that is made of a single polypeptide with only one heme group
-Dissociation curve is to the left of the haemoglobin curve and does not display a sigmoidal shape (myoglobin cannot undergo cooperative binding)
-Myoglobin's affinity for oxygen is greater than haemoglobin and becomes saturated at low oxygen concentrations
-Under normal conditions (at rest) myoglobin is saturated with oxygen and will store it until O2 levels in the body drop with intense exercise
-This allows it to provide oxygen when levels are very low (e.g. in a respiring muscle) and so delays anaerobic respiration and lactic acid formation
The next high tide will occur approximately 12 hours after the first one. So your answer choices would be B or C. I feel like the better answer choice is C. If this is wrong, feel free to delete this answer.
