Write the balanced equation for aerobic respiration and describe an experiment to demonstrate heat production by germinating seeds during respiration.

You're on a roll — 1. a) The balanced equation for aerobic respiration is: C_6H_12O_6 + 6O_2 6CO_2 + 6H_2O + Energy (ATP) This equation shows that glucose (C_6H_12O_6) reacts with oxygen (O_2) to produce carbon dioxide (CO_2), water (H_2O), and energy in the form of ATP. b) Experiment to demonstrate that heat is produced by germinating seeds during respiration: Step 1: Take two thermos flasks, A and B. Step 2: In flask A, place a quantity of germinating maize seeds. Step 3: In flask B, place an equal quantity of boiled and cooled maize seeds (which are dead and will not respire), treated with an antiseptic (e.g., formalin) to prevent bacterial decomposition. Step 4: Insert a thermometer through the cork of each flask, ensuring the bulb is immersed in the seeds. Step 5: Seal both flasks tightly with cotton wool or corks to prevent heat loss. Step 6: Record the initial temperature in both flasks. Step 7: Leave the apparatus undisturbed for 24-48 hours in a constant temperature environment. Step 8: After the incubation period, record the final temperature in both flasks. Observation: The temperature in flask A (with germinating seeds) will show a significant rise, while the temperature in flask B (with dead seeds) will remain relatively constant or show a slight change due to ambient temperature fluctuations. Conclusion: The rise in temperature in flask A indicates that heat is produced by the germinating seeds during the process of respiration. c) Characteristics of a good respiratory surface: • Large surface area: To allow for efficient diffusion of gases (oxygen and carbon dioxide) across the surface. Examples include the alveoli in lungs or gill lamellae in fish. • Thin walls: The respiratory surface must be very thin (often one cell thick) to minimize the diffusion distance for gases. • Moist surface: Gases must dissolve in a thin film of water or mucus before they can diffuse across the membrane. • Rich blood supply: A dense network of capillaries or blood vessels ensures a steep concentration gradient for gases, as absorbed oxygen is quickly transported away and carbon dioxide is brought to the surface for excretion. • Ventilation mechanism: A system to maintain a constant flow of the respiratory medium (air or water) over the surface, ensuring a continuous supply of oxygen and removal of carbon dioxide.
