What does energy come from to make nadaph in light reactions?
From electrons in photosystem I that are excited to a higher energy state by photons of light. Then NADP + is reduced to become NADPH
What does reduced mean in redox reactions?
In redox reactions, "reduced" refers to the gain of electrons by a species. When a substance is reduced, its oxidation state decreases, indicating that it has accepted electrons from another substance that is being oxidized (which loses electrons). This transfer of electrons is fundamental to redox processes, playing a crucial role in energy transfer, chemical reactivity, and various biological functions.
Are chloroplast necessary for reduction of DCPIP and why?
Yes, chloroplasts are necessary for the reduction of DCPIP because they contain the enzymes and pigments required to mediate the electron transfer reactions involved in the process. DCPIP serves as an artificial electron acceptor in photosynthesis experiments, where it is reduced by electrons from the light-dependent reactions in chloroplasts.
What is a series of photosynthetic reactions in which carbon dioxide is fixed and reduced in chloroplast?
light-dependant reactions
How is it that the light reactions do not run out of electrons?
The light reactions of photosynthesis involve a continuous flow of electrons through the electron transport chain, which is replenished by splitting water molecules to release more electrons. This process ensures a constant supply of electrons to keep the reactions running.

During cellular respiration, how is the substrate both oxidized and reduced?
During cellular respiration, the substrate is oxidized by losing electrons and reduced by gaining electrons in a series of redox reactions.

What is reddox reactions?
Redox reactions, short for reduction-oxidation reactions, involve the transfer of electrons between reactants. In these reactions, one substance gets oxidized (loses electrons) while another gets reduced (gains electrons). Redox reactions are important in various chemical processes, such as combustion, corrosion, and metabolism.

Where electrons get their energy in the light reactions?
.From photons in solar energy
Where do electrons get their energy from light reactions?
From the photons is solar energy.
What is the function of light- dependent reactions?
Build sugar
What is the main characteristics of oxidation-reduction reactions?
Oxidation-reduction reactions involve the transfer of electrons from one reactant to another. The reactant that loses electrons is oxidized, while the reactant that gains electrons is reduced. These reactions are also known as redox reactions and are crucial for energy production in living organisms.
How does NAD plus get oxidized?
NAD+ gets oxidized by accepting electrons (and protons) during redox reactions. It is reduced to NADH when it accepts these electrons.
Reduction of NADP occurs during?
NADP+ is reduced in many different places. In animals cells, for example, during the breakdown of one glucose molecule two are reduced during glycolysis, two are reduced during the oxidation of pyruvate, and 6 are created during the Krebs cycle.
