Question
Chapter 20, Problem 44P
Interpretation Introduction
Interpretation:
Efficiency of photosynthesis should be estimated.
Concept introduction:
Autotrophs can produce glucose via Calvin cycle with the use of carbon dioxide and water and using photon energy by sunlight. Three molecules of ATP and 2 molecules of NADPH are consumed to produce a hexose from CO2.

What protein(s) facilitate the transport of protons out of the thylakoid?
We can write the formula for photosynthesis as follows:
6 H2O + 6 CO2 + light energy → C6H12O6 + 6 O2
