2.41B: Understand Gas Exchange (of Carbon Dioxide and Oxygen) in Relation to Respiration and Photosynthesis

*AEROBIC RESPIRATION: Breakdown of Glucose in the presence of Oxygen to produce Carbon Dioxide and Water to release energy; occurs in the Mitochondria of the cell
s

• As a result of gas exchange, Oxygen diffuses from the Alveoli into the bloodstream where it is transported and consumed by cells via cellular respiration, producing Carbon Dioxide as a waste product that diffuses out into the Alveoli to be exhaled from Lungs

*PHOTOSYNTHESIS: Production of Carbon compounds (Glucose) in cells by using light energy from the Sun

• As a result of gas exchange, Carbon Dioxide diffuses through the Stomata into plant cells where it is transported and consumed by Chloroplasts via photosynthesis, producing Oxygen as a waste product that diffuses out through the Stomata into the Atmosphere
