- Aerobic and anaerobic respiration
- Energy is needed for the following life processes:
- Growth
- cell division
- muscle contraction
- Protein synthesis
- active transport
- nerve impulses
- respiration involves chemical reactions that break down nutrient molecules in living cells to release energy
- Aerobic respiration requires oxygen
- glucose + oxygen ---> carbon dioxide + water
- Anaerobic respiration happens in muscles during hard exercise
- Glucose is not completely broken down, so much less energy is released than during aerobic respiration
- Untitled
- glucose ---> lactic acid
- structures found in the human thorax
- Trachea
- bronchi
- alveoli
- Ribs
- intercostal muscles
- pleural membranes
- diaphragm
- Inhale and exhale
- Gas exchange in the lungs
- thin walls (just one cell thick)
- large surface area
- moist surface
- many blood capillaries
- Energy is needed for the following life processes:
