Answer 1

The nutrients from our diet are broken down during digestion into their constituent molecules, such as amino acids, fatty acids, and simple sugars, which are then absorbed into the bloodstream and delivered to cells. These nutrients serve essential roles in various cellular processes; for instance, amino acids are used to synthesize proteins that perform critical functions in the body, while glucose is a primary energy source for cellular metabolism. Essential fatty acids, found in foods like fish and walnuts, are crucial for maintaining cell membrane integrity and facilitating signaling pathways. Additionally, vitamins and minerals support metabolic reactions and cellular functions; for example, vitamin C from citrus fruits aids in collagen synthesis and antioxidant defense, while iron from spinach and red meat is vital for oxygen transport in red blood cells.
