Identify the wrong statements.
(A) Cytochrome C is a small protein attached to inner surface of the outer membrane.
(B) Electrons from complex I are transferred to ubiquinone located within the inner membrane.
(C) The temperature optimum for photosynthesis of different plants does not depend on the habitat that they are adapted to.
(D) There is no linear relationship between incident light and fixation rates at low light intensities.

(D) There is no linear relationship between incident light and fixation rates at low light intensities.
View answer and explanation
Correct option: D
A, C, D
Option A (A, B, C) is correct because statements A, B, and C contain inaccuracies regarding the location of cytochrome C, electron transfer, and temperature optima for photosynthesis.
