Answer:
The correct answer is A. The statement is true.
Explanation:
Muscle obtains ATP from glycolysis. When exercise conditions are anaerobic, glucose is degraded to lactate. Lactate is exported into the circulation and is taken up by the liver. The liver synthesizes glucose again from lactate via the gluconeogenic pathway. These two metabolic pathways that allow the coupling of the function of two tissues is what is known as the Cori cycle. The energy cost is 4 P bonds / each glucose that travels both glycolytic-gluconeogenic pathways.
Living things cannot live without eachother due to the food chain, if an animal loses it's food so will his predator and so on. Soon they will end up extinct, this is why it's important to take care of animals.
The binding of oxygen to hemoglobin differs from the oxygen binding behaviour of myoglobin because oxygen binding to hemoglobin is cooperative.
<h3>Hemoglobin - oxygen binding</h3>
Hemoglobin is the oxygen carrying protein of the blood that is located at the red blood cells. They have high affinity for oxygen.
Myoglobin is found in the muscle cells and they are contain haem proteins which they used to transport and store oxygen in the muscles.
Hemoglobin and myoglobin are two types of globin proteins that serve as oxygen-binding proteins, but binding of oxygen to hemoglobin differs from the oxygen binding behaviour of myoglobin.
This is because binding of oxygen by hemoglobin is cooperative. This means that as hemoglobin binds successive oxygens, the oxygen affinity of the subunits increases. This is opposite for myoglobin.
