Question 2

Mitchell wants to build up his muscles.He works our regularly at the gym and eats a very high protein diet,along with drinking protein supplement drinks.Do you think the protein contributes to increased muscle mass? Why or why not?

Accepted Answer

Yes, the protein definitely contributes to increased muscle mass. Protein is essential for muscle growth and repair. When you work out, you create tiny tears in your muscle fibers, and protein helps to repair and rebuild these fibers, leading to increased muscle mass. Additionally, protein is necessary for the synthesis of new muscle tissue. By consuming a high protein diet and drinking protein supplements, Mitchell is providing his body with the necessary building blocks for muscle growth. However, it's important to note that protein alone is not enough to build muscle - regular exercise and a balanced diet are also crucial factors.
