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.

- 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?arrow_forwardLife requires energy.

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?…arrow_forward
