Concept explainers
Interpretation:
Whether ATP production takes place in chloroplasts in the absence of light is to be identified and the reason for the same is to be explained.
Concept Introduction:
ATP stands for Adenosine Triphosphate.
ATP is the primary energy carrier in the living organisms.
The energy of the
An electron transport chain is the series of electrons transferred 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

- REFLECT AND APPLY Would you expect the production of sugars by plants in photosynthesis to be an exergonic or endergonic process? Give the reason for your answer.arrow_forwardREFLECT AND APPLY Would nature rely on the same enzyme to catalyze a reaction either way (forward or backward) if the DG were 0.8kcalmol1? If it were 5.3kcalmol1?arrow_forwardREFLECT AND APPLY Why is it important that energy released by exergonic reactions can be used to provide energy for endergonic reactions?arrow_forward
- REFLECT 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_forwardREFLECT 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 Metabolic cycles are rather common (Calvin cycle, citric acid cycle, urea cycle). Why are cycles so useful to organisms?arrow_forward
- REFLECT AND APPLY (a) The major energy storage compound of animals is fats (except in muscles). Why would this be advantageous? (b) Why dont plants use fats/oils as their major energy storage compound?arrow_forwardREFLECT AND APPLY Outline the methods you would use to pro- duce human growth hormone (a substance used in the treatment of dwarfism) in bacteria.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 Does the net gain of ATP in glycolysis differ when glycogen, rather than glucose, is the starting material? If so, what is the change?arrow_forwardREFLECT AND APPLY Explain how phosphorylation is involved in the function of the sodiumpotassium ATPase.arrow_forwardREFLECT AND APPLLY Is the reaction of 2-phosphoglycerate to phosphoenolpyruvate a redox reaction? Give the reason for your answer.arrow_forward
