Question
Chapter 8.2, Problem 3CC
Summary Introduction
To predict:
The rate of synthesis of ATP when a compound is added to the solution that makes the membranes freely permeable to hydrogen ions.
Introduction:
In the light-dependent reactions, the water is split into oxygen, electrons, and hydrogen ions. The hydrogen ions move along ETC (electron Chain transport) in the inter-membranous space from the matrix. The chemiosmosis is the movement of hydrogen ion from higher concentration to lower concentration, through which ATP (adenosine triphosphate) is formed.

WHAT IF? A classmate proposes that mitochondria andchloroplasts should be classified in the endomembranesystem. Argue against the proposal.
Q) Start with a photon of sunlight and a carbon atom in a molecule of carbon dioxide in the atmosphere: model/diagram their pathway from that starting point to their final destination as a glucose molecule that is used for energy in a cell in the plant root. Following your diagram/model, provide a written explanation for what your diagram/model depicts. Make sure both your model and explanation are clear, concise, and have the appropriate level of detail to clearly demonstrate you understand photosynthesis, cellular respiration, and the movement of mass and energy in plants.
