Study Notes
Biochemistry and Metabolism
- Biochemistry is the study of chemical processes in living organisms
- Metabolism is the sum of all chemical reactions in a living organism, responsible for converting nutrients into energy and building and repairing tissues
Biochemistry and Metabolism in Illness and Recovery
- During illness, the body's biochemistry and metabolism are altered, leading to changes in hormone levels, nutrient metabolism, and immune function
- After recovery, the body's biochemistry and metabolism return to normal
Biochemical Aspects in Illness
- Increased inflammation can damage tissues and contribute to illness, such as cytokine storm in COVID-19
- Increased oxidative stress occurs when there is an imbalance between free radicals and antioxidants, leading to cell damage
- Free radicals are unstable molecules that can damage cells, while antioxidants neutralize them
- Altered nutrient metabolism during illness can lead to nutrient deficiencies and weight loss
- Hormone levels can change during illness, leading to a variety of symptoms, as hormones regulate many bodily functions
Understand how biochemistry and metabolism change during illness and recovery, including alterations in hormone levels, nutrient metabolism, and immune function.
