Question
Chapter 19, Problem 16P
Interpretation Introduction
Interpretation:
The various sources of protons which participate in the generation of a proton gradient in chloroplastsare to be stated.
Concept introduction:
Photosynthesis is a reaction in which carbon dioxide and water combine together in the presence of sunlight to form glucose and oxygen. The organelle of plants which helps in the conduction of photosynthesis at where the chlorophyll traps the energy obtained from sunlight is known as chloroplasts.

Fo-F1 ATPase. The energy for ATP synthesis from ADP and Pi is provided by the downhill transport of protons through the rotary FoF1 ATP synthase (lecture 22). The enzyme has 3 a-b and 12 ‘c’ subunits. The mitochondrion maintains Df=180 mV (negative inside), pHin = 8, pHout=7, [Pi] = 3 mM and ADP is present as well.
How much energy is available (from the proton electrochemical gradient) for ATP synthesis under these conditions (in kJ/mol)?
What [ATP]/[ADP] ratio will be established at steady-state under these conditions?
What would be the [ATP]/[ADP] ratio if the enzyme had only 9 ‘c’ subunits? Remember that full revolution of the crank (gamma subunit) produces 3 ATP.

- photosynthesis. Historical Discovery Process The chemical changes that occur during photosynthesis have been investigated for the past 300 years. The general highlights of these discoveries help us to understand the basic process of photosynthesis. Three centuries ago people wondered where plants came from. They knew that plants grew out of the ground, but how that happened was a complete mystery to them. The first step in answering the question was to plant a small tree in a large pot supported off the ground. They did this so that the soil of the container was separated from the soil of the earth. Only the dirt in the pot was available to the plant. The people cared for the plant during one year. At the end of the year the small tree had gained 100 kg.
