The light energy absorbed is funneled to a trap pigment that absorbs at a light wavelength of 700 nm. One of its products is oxygen. It can divert electrons for cyclic photophosphorylation. It happens when light is used directly for respiration. Ribulose bisphosphate carboxylase reacts with oxygen instead of CO 2 .
Light is used to create an electrochemical gradient of protons.
Oxygen reacts with mitochondria, stimulating the rate of respiration. Click this button to turn in your homework. Click this button to clear all of the answers you've entered and start over. If you start over, remember to re-enter your name and student ID also. All rights reserved.
