Practice questions testing deep understanding of C3, C4 pathways, and photophosphorylation.
Q1. Rubisco is the most abundant enzyme on Earth, responsible for fixing CO2 in the Calvin Cycle. However, it has a major biological flaw: it can also bind to Oxygen (causing wasteful photorespiration). Explain how C4 plants (like sugarcane) have evolved a specialized leaf anatomy to overcome this flaw in hot, dry climates.
Q2. During the Light Reaction, how exactly is ATP produced? Explain the mechanism of the proton gradient as described by the Chemiosmotic Hypothesis.
Q3. Assertion (A): Chlorophyll 'a' is considered the primary photosynthetic pigment. Reason (R): It is the only pigment capable of physically converting light energy into chemical energy by ejecting high-energy electrons from its reaction center.
