(a)

Summary Introduction

To predict: The way in which the noncyclic electron flow was affected in the hcef mutant plants as compared to normal Arabidopsis plants.

Introduction: A mutant of the Arabidopsis thaliana plant has been isolated by Livingston et al. This mutant plant, called the hcef plant because it has a higher flow of electrons in the cyclic process around the photosystem I.

(b)

Summary Introduction

To predict: The effect of mutation on the light-driven proton flux across the thylakoid membrane.

Introduction: A mutant of the Arabidopsis thaliana plant has been isolated by Livingston et al. This mutant plant, called the hcef plant because it has a higher flow of electrons in the cyclic process around the photosystem I.

(c)

Summary Introduction

To predict: The effect of the mutation on the activity of PSII.

Introduction: A mutant of the Arabidopsis thaliana plant has been isolated by Livingston et al. This mutant plant, called the hcef plant because it has a higher flow of electrons in the cyclic process around the photosystem I.

(d)

Summary Introduction

To predict: The enzyme which is defective in the mutant hcef plant that is causing a large increase in the level of fructose-1,6-bisphosphate in the stroma of the mutant plant.

Introduction: A mutant of the Arabidopsis thaliana plant has been isolated by Livingston et al. This mutant plant, called the hcef plant because it has a higher flow of electrons in the cyclic process around the photosystem I.

(e)

Summary Introduction

To predict: The way in which the starch synthesis in the stroma is affected in mutant hcef plants as compared to normal Arabidopsis plants.

Introduction: A mutant of the Arabidopsis thaliana plant has been isolated by Livingston et al. This mutant plant, called the hcef plant because it has a higher flow of electrons in the cyclic process around the photosystem I.

+ Explain why a strain of yeast with a defect in the enzyme alcohol dehydrogenase can grow well under aerobic conditions, but not under anaerobic conditions. The yeast strain grows well when aerobic because acetaldehyde is quickly converted to lactate. The yeast strain uses CO₂ to generate NAD+ when aerobic, but GAPDH needs NADH when anaerobic. The yeast strain grows equally well under aerobic and anaerobic, but polyphenol is lethal to this strain. The yeast strain cannot oxidize NADH to generate NAD+ for the GAPDH reaction when anaerobic. The yeast strain needs to generate ethanol in order to stimulate the PFK- 1 reaction when anaerobic.
. In another key reaction in glycolysis, dihydroxyacetone phosphate (DHAP) is isomerized into glyceraldehyde-3-phosphate (GAP) Because ∆G°′ is positive, the equilibrium lies to the left. (a) Calculate the equilibrium constant and the equilibrium fraction of GAP from the above, at 37 °C. (b) In the cell, depletion of GAP makes the reaction proceed. What will ∆G be if the concentration of GAP is always kept at 1/100 of the concentration of DHAP?
EDTA was used as photophosphorylation uncoupler/inhibitor of ATP synthesis. What is EDTA and what is its mode of uncoupling? What is its mode of uncoupling in cholorplast?  I know EDTA is ethylenediaminetetraacetic acid and is a chelating agent. I do not understand how to answer the question on its mode of uncoupling.  Jagendorf, A.T, and E. Uribe, “ATP formation caused by acid-base transition of spinach chloroplasts, “ Proceedings of the National Academy of Sciences (USA) 55 (1965): 170-177
