Concept explainers
Interpretation:
The similarity of the evolutionary implications in the structure and function of ATP synthase in chloroplast and mitochondria is to be explained.
Concept Introduction:
The energy of the
An electron transport chain is the series of electron transfers from an electron donor to an electron acceptor. It is referred to as a
It is the last component of aerobic respiration and is the only reaction that utilizes atmospheric oxygen. It takes place in the inner mitochondrial space.
Oxidative phosphorylation is the

Give the reason for your answer.arrow_forwardREFLECT AND APPLY What is the role of citrate in the transport of acetyl groups from the mitochondrion to the cytosol?arrow_forwardREFLECT AND APPLY What is the approximate P/O ratio that can be expected if intact mitochondria are incubated in the presence of oxygen, along with added succinate?arrow_forward

- REFLECT AND APPLY Why is it useful to plot rate data for enzymatic reactions as a straight line rather than as a curve?arrow_forwardREFLECT AND APPLY What is the relationship between a transition-state analog and the induced-fit model of enzyme kinetics?arrow_forwardREFLECT AND APPLY If photosynthesizing plants are grown in the presence of 14CO2, is every carbon atom of the glucose that is produced labeled with the radioactive carbon? Why or why not?arrow_forward
- REFLECT AND APPLY A model is proposed to explain the reaction catalyzed by an enzyme. Experimentally obtained rate data fit the model to within experimental error. Do these findings prove the model?arrow_forwardREFLECT AND APPLY Explain how phosphorylation is involved in the function of the sodiumpotassium ATPase.arrow_forwardREFLECT AND APPLY Show how the reactions of the electron transport chain differ from those in Question 3 when FADH2 is the starting point for electron transport. Show how the reactions that liberate enough energy to drive the phosphorylation of ADP differ from the pathway when NADH is the starting point.arrow_forward
