There are three phases to the light-independent reactions, collectively called the Calvin cycle: carboxylation, reduction reactions, and ribulose 1,5-bisphosphate (RuBP) regeneration. Though it is called the “dark reaction”, the Calvin cycle does not actually occur in the dark or during night time.

Which is required for the light-independent reactions in photosynthesis to occur?

Water molecules are split. Which is required for the light-independent reactions in photosynthesis to occur? … The L-D reactions require light energy and water, and the L-IND reactions require ATP, NADPH and CO2.

What provides the energy for light independent reactions?

Figure 1. Light reactions harness energy from the sun to produce chemical bonds, ATP, and NADPH. These energy-carrying molecules are made in the stroma where carbon fixation takes place.

What are the 4 reactants going into the light-dependent reactions?

The reactants in the light-dependent chemical reaction are adenosine diphosphate (ADP), oxydized nicotinamide adenine dinucleotide phosphate (NADP+) and the hydrogen in water.

What are the reactants and products of the light independent reactions quizlet?

The products of light-dependent pathways of photosynthesis are Oxygen, ATP, and NADPH. The reactants of light-independent reactions are ATP, NADPH, and Carbon Dioxide. The main purpose of the light independent reaction is to produce glucose.

What products of the light-dependent reactions are used during the light-independent reactions?

The light-dependent reactions convert light energy into chemical energy, producing ATP and NADPH. The light-independent reactions use the ATP and NADPH from the light-dependent reactions to reduce carbon dioxide and convert the energy to the chemical bond energy in carbohydrates such as glucose.

What is NADPH and ATP?

ATP is a versatile energy currency for cells while NADPH is a source of electrons that can pass along to an electron acceptor. The function of ATP is that it acts as a major energy storing and transferring molecule. On the other hand, NADPH works as a coenzyme and reducing the power of biochemical reactions.
