A student created the following table as a study guide. Evaluate the accuracy of the student's table.Should any entry in the table be changed to correct an error?
A) No, the table is accurate as written.
B) Yes, both sets of reactions should be indicated as exergonic.
C) Yes, the locations of the two sets of reactions should be reversed.
D) Yes, input of oxygen and output of water should be shown with the light-independent reactions.
E) Yes, the light-dependent reactions should be shown as taking in water and releasing oxygen.

Question

E) Yes, the light-dependent reactions should be shown as taking in water and releasing oxygen.

Quizplus · Accepted Answer

The student's table incorrectly shows the light-dependent reactions as taking in oxygen and releasing water. In reality, the opposite is true: the light-dependent reactions take in water and release oxygen. This is a common mistake made by students, as it's easy to get confused about which reactants and products are associated with which stage of photosynthesis. Therefore, the correct answer is E, as the table should be revised to show the correct inputs and outputs for the light-dependent reactions. The other answer choices do not correctly identify errors in the student's table.
