The evolutionary selection process for glycogen metabolism<span> reflects the requirements of rendering large amounts of glucose into an osmotically stable but readily soluble </span>substrate<span> for rapid mobilization. Therefore glycogen </span>serves<span> as a glucose reserve and </span>substrate<span> buffer for local </span>energy<span> demand.</span>
The answer is 12.5%.
Each gram of protein has four calories. Therefore, 50 grams of protein contain 200 calories. In order to find the percentage of total energy intake that comes from protein, we need to do the division: 200/1600 * 100 = 12.5. Protein is needed for body growth and maintenance and energy.
