Study Notes
Aerobic Respiration
- Word equation for aerobic respiration: Glucose + Oxygen → Carbon Dioxide + Water + Energy
- Oxygen is sourced from the atmosphere.
Blood Oxygen Transport
- Hemoglobin in red blood cells binds to oxygen in the lungs.
- Oxygen is transported from the lungs to the body tissues where it is needed for cellular processes.
Waste Products of Aerobic Respiration
- Waste products, such as carbon dioxide, must be excreted to prevent toxicity in the body.
Aerobic vs. Anaerobic Respiration
- Aerobic respiration requires oxygen while anaerobic respiration occurs without it.
Anaerobic Respiration
- Word equation for anaerobic respiration varies based on organism, commonly: Glucose → Lactic Acid + Energy.
Balanced Diet
- A balanced diet for humans includes a variety of nutrients needed for health, including carbohydrates, proteins, fats, vitamins, and minerals.
- Principal sources of carbohydrates include grains, fruits, and vegetables; they provide energy.
- Dietary importance of proteins includes tissue repair and growth; found in meat, dairy, and legumes.
- Malnutrition can lead to undernutrition or obesity, affecting overall health.
Nutritional Deficiencies
- Vitamin D deficiency leads to weakened bones and potential developmental issues.
- Effects of vitamin B deficiencies can include anemia and fatigue.
Digestion Process
- Digestion is the breakdown of large molecules into smaller units: carbohydrates into simple sugars, fats into fatty acids and glycerol, proteins into amino acids.
Enzyme Secretion in Digestion
- Amylase is secreted in the saliva and pancreas.
- Protease is secreted in the stomach and pancreas.
- Lipase is secreted in the pancreas.
Enzyme Action
- Amylase breaks down starches into simple sugars.
- Protease breaks down proteins into amino acids.
- Lipase acts on fats, breaking them down into fatty acids and glycerol.
