Aerobic Respiration Notes

Aerobic Respiration

• Living things need energy for movement, growth, warmth, and repair.
• Respiration is the process of getting energy from food; aerobic respiration is most common.
• Aerobic respiration equation: glucose + oxygen \rightarrow carbon dioxide + water + energy
• Cells need glucose and oxygen for aerobic respiration.
  • In humans, glucose is transported by blood plasma from the small intestine.
  • Oxygen is carried by hemoglobin in red blood cells from the lungs.
• Glucose combines with oxygen in cells, releasing energy, carbon dioxide, and water.
• Waste products are carried by blood plasma to the lungs for excretion.
• Aerobic respiration occurs in animal and plant cells.
• It starts in the cytoplasm and finishes in the mitochondria, where most energy is released.
