Question 01 / Bioenergetics Quantitative study of energy relationships in biological systems obeys. A Option A: Bioenergetics B Option B: Laws of thermodynamics C Option C: Laws of thermo chemistry D Option D: Laws of chemical energetic Correct answer B. Laws of thermodynamics Show answer Open question
Question 02 / Bioenergetics Which of the following is a compensation point: A Option A: Leaves respire and utilize O2 and release CO2. B Option B: Photosynthesis and respiration occur at same rate. So there is not net exchange of gases between atmosphere and plants. C Option C: Rate of photosynthesis increases, so do the O2 production, with a net release of oxygen coupled with the uptake of CO2. D Option D: Rate of respiration becomes more than rate of photosynthesis. Correct answer B. Photosynthesis and respiration occur at same rate. So there is not net exchange of gases between atmosphere and plants. Show answer Open question
