Question
Chapter 19, Problem 17P
Interpretation Introduction
Interpretation:
The fraction of energy trapped as high-energy electrons for 700-nm light absorbed by photosystem I should be determined.
Concept introduction:
The energy possessed by releasing electrons can be calculated as Gibbs free energy, by the following reaction.
A photon can be introduced as a piece of energy which has no mass. The relationship between the energy of a photon and its wavelength can be expressed with the following Planck-Einstein equation.

Chemiosmosis. ATP synthesis in chloroplasts is usually light dependent; it does not happen in the dark.
When researchers shifted isolated chloroplasts from a low pH solution to a more alkaline (higher pH) solution, ATP synthesis occurred even in the absence of light! This was an experiment used to support the chemiosmosis mechanism of ATP formation in chloroplasts. Why?
What would happen if the isolated chloroplasts were shifted to a lower pH solution?
What would be the results if the above experiments were performed in the presence of light?
If these experiments were performed in mitochondria instead of chloroplasts, what results would we expect?
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. (The actual data from this experiment
have been changed to simplify the discussion.)
1. What do you think the experimenters considered as two possible
sources for the substances (matter) that became incorporated into new
tree growth?…
Life requires energy. Describe the basic principles of bioenergetics in an animal cell. How is the flow and transformation of energy different in a photosynthesizing cell? Include the role of ATP and enzymes in your discussion.
