(a)

Summary Introduction

To explain: The direction in which the equilibrium lies and the value of equilibrium constant at 25oC

Introduction:  Equilibrium is attained in a reaction when the rate at which the products are formed becomes equal to the rate at which the reactants are being consumed. One can change the direction of the reaction by changing the conditions around the reaction. Change in pressure or in temperature can make the reaction move in forward or backward direction.

(b)

Summary Introduction

To determine: The direction in which the reaction proceeds in standard conditions and the value of ΔG'  for the reaction in that direction.

Introduction: Equilibrium is attained in a reaction when the rate at which the products are formed becomes equal to the rate at which the reactants are being consumed. One can change the direction of the reaction by changing the conditions around the reaction. Change in pressure or in temperature can make the reaction move in forward or backward direction.

(c)

Summary Introduction

To determine: The value for ΔG' at 25oC if concentration of G3P is maintained at 1% of the DHAP concentration in the given reaction for glycolytic pathway.

Introduction: Equilibrium is attained in a reaction when the rate at which the products are formed becomes equal to the rate at which the reactants are being consumed. One can change the direction of the reaction by changing the conditions around the reaction. Change in pressure or in temperature can make the reaction move in forward or backward direction.

(d)

Summary Introduction

To determine: The ratio of G3P to DHAP to ensure that the reaction is exergonic by at least -3.0 kacal/mol at 25oC.

Calculate the energy cost of the Calvin cycle combined with glycolysis and oxidative phosphorylation, that is, the ratio of the energy spent synthesizing starch from CO2 and photosynthetically produced NADPH and ATP to the energy generated by the complete oxidation of starch. Assume that each NADPH is energetically equivalent to 2.5 ATP and that starch biosynthesis and breakdown are mechanistically identical to glycogen synthesis and break down.
The compound Carbonyl cyanide-p-trifluoromethoxyphenyl hydrazone (FCCP) acts as an uncoupler of electrochemical gradients (in both mitochondria and chloroplasts) by shuttling protons across membranes. Predict the effect of a high dose of FCCP on the synthesis of ATP and NADPH in photosynthesis. Rationalize your answersAnswer separately with prediction and reason please thank you so much
Question:- List the different molecules, an electrons is part of, as it moves from NADPH through the light-independent phase of photosynthesis and is synthesized into a substrate that can feed it into a NADH molecule as part of aerobic cellular respiration. Provide 2 different options for NADH production.
