This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Explain photorespiration and how the enzyme rubisco plays a major role in that process during photosynthesis?
ovules
photo respiration occurs usually in times of drought. limited water forces the plant to close stomata - therefore blocking co2. with lo concentrations of co2 and high concentrations of 02 - the enzyme rubisco starts to bind 02 instead of co2. this pr
