Organic Energy-rich Energy-poor 18 / 20 C6H12O6 + 6O2? 6CO2 + 6H20 + ENERGY represents. Aerobic respiration Photosynthesis Anaerobic respiration 19 / 20 At which times there is no net gaseous exchange between leaves and the atmosphere. Daytime Dawn & Dusk Midnight 20 / 20 Which of the following is a compensation point Leaves respire and utilize O2 and release CO2 Photosynthesis and respiration occur at the same rate. So there is no net exchange of gases between atmosphere and plants The rate of photosynthesis increases, so does the O2 production, with a net release of oxygen coupled with the uptake of CO2 Your score is The average score is 0% LinkedIn Facebook Twitter VKontakte 0% Restart quiz Check out for more quizzes like the bioenergetics quiz for mdcat 2022 preparation.
