Electrons are crucial in cellular respiration and photosynthesis as they facilitate energy transfer through redox reactions. In cellular respiration, NAD+ accepts electrons during the breakdown of glucose, becoming NADH, which then donates electrons to the electron transport chain to produce ATP. Similarly, in photosynthesis, NADP+ accepts electrons during the light-dependent reactions, forming NADPH, which provides the reducing power for the Calvin cycle to synthesize glucose. Both processes rely on these electron carriers to efficiently convert energy from one form to another.
What else can I help you with?
What are the electrons carriers in cellular respiration?
NAD+, (or nicotinamide adenine dinucleotide)
After hydrogens and electrons are stripped from NADPH NADP plus?
After hydrogens and electrons are stripped from NADPH, it is converted to NADP+. This process typically occurs during cellular respiration or photosynthesis, where NADPH donates its electrons in redox reactions. The resulting NADP+ can then be recharged by accepting electrons and hydrogen ions again, allowing it to participate in further metabolic processes. This cycling between NADPH and NADP+ is crucial for maintaining cellular energy and reducing power.
Electrons are excited in photosystem 1 what do these electrons combine with in order to produce an energy-carrying molecule?
NADP+
What part of the photosynthetic cycle involves an enzyme taking a molecule of NADP and adding two electrons and one proton to it?
The part of the photosynthetic cycle that involves an enzyme adding two electrons and one proton to a molecule of NADP is known as the Calvin cycle. Specifically, this process occurs during the reduction phase, where NADP+ is reduced to NADPH. This reaction is facilitated by the enzyme ferredoxin-NADP+ reductase (FNR), which plays a crucial role in transferring electrons from photosystem I to NADP+, ultimately contributing to the formation of glucose and other carbohydrates.
What molecule is produced by adding two electrons and one proton to NADP?
NADPH
What are the electrons carriers in cellular respiration?
NAD+, (or nicotinamide adenine dinucleotide)
How does NADP transfer electrons?
NADP transfers electrons by accepting them from other molecules in redox reactions, taking on two electrons and a proton to form NADPH. This process typically occurs in metabolic pathways such as photosynthesis and cellular respiration, where NADP acts as an electron carrier to facilitate energy production.
When NADPH gives up its electrons?
NADPH becomes oxidized to NADP+, losing the electrons it carried. The electrons are typically used in cellular processes, such as in photosynthesis or cellular respiration, and NADP+ can then pick up more electrons to become NADPH again.

Is nadp a carrier of electrons?
yes it is
What is the equation that shows how nadp is changed into nadph?
NADP+ accepts and holds 2 high-energy electrons along with a hydrogen ion (H+).
Do NADP plus store electrons for photosynthesis?
no
What ingredients are required to transform NADP into NADPH?
To transform NADP into NADPH, the ingredients required are hydrogen ions (H), electrons, and an enzyme called NADP reductase.
How is the function of NAD plus similar to that of NADP plus?
Both NAD+ and NADP+ are coenzymes involved in redox reactions in cells. They both act as electron carriers, accepting and donating electrons during metabolic processes. NAD+ is primarily involved in catabolic reactions, while NADP+ is involved in anabolic reactions.
What are three hydrogen carriers involved in aerobic respiration?
NADH, FADH2, and flavin adenine dinucleotide (FAD) are three hydrogen carriers involved in aerobic respiration. These molecules carry high-energy electrons to the electron transport chain, where they transfer the electrons to generate ATP through oxidative phosphorylation.
Electrons are excited in photosystem 1 what do these electrons combine with in order to produce an energy-carrying molecule?
NADP+
What is the final electron receptor in cellular respiration?
oxygen is used to pull electrons down to the Electron Transport Chain which pumps H+ to create H+ gradient :)
