Amino acids are simple molecules found in plant and animal tissues, serving as the building blocks of proteins. Biologists study these and other aspects of living organisms, including cells, which are the smallest units of life. Blood vessels transport blood throughout the body, while the colon, part of the large intestine, helps process waste. Cancer is a group of diseases marked by uncontrolled cell growth, leading to tumors and potentially death. COVID-19, a disease caused by the SARS-CoV-2 virus, became a global pandemic in 2020, causing severe respiratory symptoms. The immune system defends against infections, which are diseases spread by microbes. Inflammation is the body’s response to injury and can worsen diseases like heart disease and diabetes. Understanding these biological concepts is crucial for maintaining health and addressing diseases that impact society.
QUESTION: How might advancements in understanding amino acids and the immune system influence future medical treatments?
