How would you explain the significance of NADPH in photosynthesis and NADH in cellular respiration?
NAD+/NADH play a role as redox agent (mainly by abstracting hydrogen ions (H+ or H-) or transferring hydrogen ions). They act on oxidation processes and reduction processes in metabolism of sugar.
The chemicals in glycolysis and TCA cycle undergo a series of oxidation reaction going from glucose to carbon dioxide. This means that electrons is ultimately transferred to oxygen (which subsequently reduces it to H2O)
Electron is ultimately transported to O2 in electron transport chain (a reduction process

NAD+/NADH
The process of conversion from C6H12O6 to CO2 do not occur in a single step but through a series of redox processes.
So you can see that the action of a variety of enzymes like dehydrogenase enzymes acts to remove H+ from substrates/intermediates in glycolysis and TCA processes.
Remember that these enzymes are located far away from each other. So the removal of proton must be done with the help of a molecule that can carry the proton between different enzymes. Thiw is done using NADH (reduced state) or NAD+ (oxidized state)

GLYCOLYSIS
In glycolysis , NAD+ is used in conversion from GADP to 1,3BPG as can be seen below.

You can see how H- is removed from OH group
TCA CYCLE
In TCA cycle , it occurs in 4 different processe as highlighted in red.

Both molecules play critical roles in energy transfer processes: NADPH in photosynthesis acts as a reducing agent, donating electrons to help convert carbon dioxide into glucose; NADH in cellular respiration carries electrons to the electron transport chain, facilitating ATP production through oxidative phosphorylation.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
