Can light dependent reactions occur in the dark?

Answer 1

No, light is a prerequisite for light-dependent reactions to occur, as the title states.

Light is necessary for the light-dependent reaction because it activates the two systems that make up the reaction, called Photosystem 1 and Photosystem 2, by absorbing light. Eventually, the electrons gain so much kinetic energy that they leave the Photosystem and move through the electron transport chain. If they are unable to obtain enough energy from sunlight, the electron transport chain will not occur.

No, because light energy is needed to propel the conversion of light energy into chemical energy in the form of ATP and NADPH, light-dependent reactions cannot take place in the absence of light.

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.
