Does cellular respiration use NADPH?
No, cellular respiration primarily uses NADH as an electron carrier, not NADPH. NADH is generated during glycolysis and the citric acid cycle, and it is used in the electron transport chain to produce ATP. NADPH is typically more involved in anabolic processes like fatty acid and nucleotide biosynthesis.
What are the final electron acceptors for the electron transport chains in light reactions of photosynthesis and in cellular respiration?
In the light reactions of photosynthesis, the final electron acceptor is NADP+, which gets reduced to NADPH. In cellular respiration, the final electron acceptor is oxygen, which gets reduced to form water.
Which high-energy molecule and electron carrier are produced by the light reaction of photosynthesis?
NADPH and ATP are produced by the light reactions. The ATP is a high energy molecule produced by photophosphorylation while the NADPH is produced at the end of the electron transport chain.
What is passage of electrons along a series of carrier molecules from a higher to a lower energy level?
This is known as the electron transport chain, which occurs during cellular respiration and photosynthesis. Electrons move along a series of carrier molecules embedded in the inner mitochondrial membrane or thylakoid membrane, releasing energy that is used to generate ATP or NADPH, respectively. The flow of electrons helps create a proton gradient that drives ATP synthesis.
What is the electron carrier in photosynthesis that will donate electrons to co2 so it can be fixed into sugar is?
The electron carrier in photosynthesis that donates electrons to CO2 for its conversion into sugar is NADPH (nicotinamide adenine dinucleotide phosphate). NADPH is produced during the light-dependent reactions of photosynthesis and transfers high-energy electrons to the Calvin cycle to facilitate the fixation of CO2 into sugar molecules.

What are the final electron acceptors for the electron transport chains in light reactions of photosynthesis and in cellular respiration?
In the light reactions of photosynthesis, the final electron acceptor is NADP+, which gets reduced to NADPH. In cellular respiration, the final electron acceptor is oxygen, which gets reduced to form water.
What does cellular respiration give off for photosynthesis?
ATP and NADPH.
What is the electron carrier molecule when carrying excited electrons it becomes NADPH?
NADP
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.
What are the electron carrier molecules of kerbs cyle and kalvin cycle?
The electron carrier molecules of the Krebs cycle are NADH and FADH2. In the Calvin cycle, the electron carrier molecule is NADPH.
What is the difference between NADP and NADPH in terms of their roles in cellular metabolism and redox reactions?
NADP and NADPH are both coenzymes involved in redox reactions in cellular metabolism. NADP primarily functions in anabolic reactions, such as biosynthesis, while NADPH is the reduced form of NADP and serves as a key electron carrier in these reactions. NADPH is essential for processes like fatty acid and nucleotide synthesis, while NADP is more involved in maintaining cellular redox balance.
When during cellular respiration is NADPH created?
The oxidative phase of the pentose phosphate pathway
What are two high energy electron carriers used in cellular respiration that are not used in photosynthesis?
Two high energy electron carriers used in cellular respiration that are not used in photosynthesis are NADH (Nicotinamide Adenine Dinucleotide) and FADH2 (Flavin Adenine Dinucleotide). These molecules play a crucial role in transferring electrons from the breakdown of glucose to the electron transport chain in cellular respiration, ultimately leading to the production of ATP. In photosynthesis, the electron carriers NADH and FADH2 are not involved as the process uses different electron carriers such as NADPH (Nicotinamide Adenine Dinucleotide Phosphate) and ATP.
Is the electron transport part of cellular respiration?
Yes, it's ultimate goal is to produce ATP (adenosine triphosphate), and its end product is a oxygen molecule which then combines with a free floating hydrogen proton to form H2O. The H2O is what is used to start the process of photosynthesis over again because that is where the electron particle comes from to aid in making NADPH (energy).
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.
Which high-energy molecule and electron carrier are produced by the light reaction of photosynthesis?
NADPH and ATP are produced by the light reactions. The ATP is a high energy molecule produced by photophosphorylation while the NADPH is produced at the end of the electron transport chain.
