Flashcards

Cellular Respiration

The process where cells convert glucose and oxygen to energy, carbon dioxide, and water.

Cellular Respiration Location

Takes place in the mitochondria of the cell.

Artery Function

Carries oxygenated blood away from the heart, except for the pulmonary artery, with thick walls.

Vein Function

Carries deoxygenated blood to the heart, except for the pulmonary vein, with thinner walls and valves.

Study Notes

Cellular Respiration

Cellular respiration converts glucose and oxygen into energy (ATP), carbon dioxide, and water.
The word equation is: Glucose + Oxygen → Energy (ATP) + Carbon Dioxide + Water
The chemical equation is: C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + Energy (ATP)
This process occurs in the mitochondria.

Blood Vessel Arrangement

Arteries carry oxygenated blood (except pulmonary artery) away from the heart and have thick muscular walls.
Veins carry deoxygenated blood (except pulmonary veins) to the heart and have thinner walls and valves.
Capillaries are tiny vessels where gases, nutrients, and waste products are exchanged.
