A fitness cоаch is helping twо clients with different gоаls. One client is trying to lose body fаt, while the other is focused on building and maintaining muscle mass. Both clients are following exercise programs, but are unsure how their bodies use different nutrients during these processes. The coach explains that the body adjusts its metabolism depending on nutrient availability, energy needs, and physical activity. When energy intake is low, the body may rely more heavily on stored fats for fuel, while protein metabolism plays an important role in maintaining and repairing muscle tissue. You have been asked to explain the biochemical processes that allow the body to adapt to these different metabolic demands. Your Task Using concepts from this unit, explain the following: How can fatty acids be broken down to produce energy? How does the body store excess energy as fat when nutrient intake is high? How do amino acids contribute to protein turnover and tissue maintenance? Why does metabolism change depending on nutritional state and energy needs? Focus on explaining how metabolic pathways allow the body to adapt to different nutritional and energy conditions.
