What is the difference between NAD and NADH?
NAD (nicotinamide adenine dinucleotide) is a coenzyme that can accept or donate electrons during cellular respiration. NADH is the reduced form of NAD, meaning it has gained electrons. NADH is a high-energy molecule that carries electrons to the electron transport chain for ATP production.
How do high energy electrons contribute to the process of photosynthesis in plants?
High energy electrons contribute to the process of photosynthesis in plants by being transferred along the electron transport chain, which generates a proton gradient across the thylakoid membrane. This gradient is used to produce ATP, a molecule that provides energy for the synthesis of glucose during the light-dependent reactions of photosynthesis.
What does NADH carry that can be used in the process of chemiosmosis?
NADH carries high-energy electrons that can be used in the process of chemiosmosis to create a proton gradient across the inner mitochondrial membrane. This proton gradient is then used to generate ATP through ATP synthase.
Electrons that have been excited by light energy absorbed by a chlorophyll molecule?
Excited electrons in a chlorophyll molecule are transferred through a series of proteins in the thylakoid membrane, known as the electron transport chain, generating ATP and NADPH through the process of photosynthesis. These high-energy molecules will then be used in the Calvin cycle to produce glucose from carbon dioxide.
What particle gains energy gets excited?
An electron gains energy and becomes excited when it absorbs energy from photons or collides with other particles at high speeds. This excitation can result in the electron moving to a higher energy level within an atom or molecule.
What high-energy molecule do excited electrons generate?
ATP
What is the main product of the Krebs cycle?
Type your answer here... A four-carbon molecule
What does nadph carry?
NADPH carries high-energy electrons used in anabolic reactions, such as biosynthesis and the reduction of compounds. It is an important cofactor in metabolic pathways like photosynthesis and fatty acid synthesis, providing reducing power for these processes.
What is a carrier molecules?
A carrier molecule is a compound that can accept a pair of high energy electrons and transfer them along with most their energy to another molecule. Straight out of the 9th grade textbook
What goes in and comes out of glycolysis?
In glycolysis, glucose (a 6-carbon sugar molecule) goes in and is converted into two molecules of pyruvate (a 3-carbon compound). This process also produces ATP (energy) and NADH (a molecule that carries high-energy electrons).
Photosynthesis carrier molecules?
In photosynthesis, carrier molecules like NADPH and ATP play crucial roles in transferring energy and electrons during the light-dependent reactions. NADPH carries energized electrons to fuel the Calvin cycle, while ATP provides energy for glucose synthesis. These molecules help convert light energy into chemical energy that plants use for growth and survival.
Which molecule are high-energy electrons from glycolysis and the Krebs cycle ultimately transferred to?
High-energy electrons from glycolysis and the Krebs cycle are ultimately transferred to oxygen molecules during oxidative phosphorylation in the electron transport chain to produce ATP.
Is NAD plus a high energy molecule?
NAD+ (nicotinamide adenine dinucleotide) is not considered a high-energy molecule in itself; rather, it functions as an electron carrier in redox reactions within cells. It exists in a balanced state with its reduced form, NADH, which stores energy. When NAD+ accepts electrons during metabolic processes, it becomes NADH, which can then donate these electrons to the electron transport chain to generate ATP, the primary energy currency of the cell. Thus, while NAD+ plays a critical role in energy metabolism, it is not a high-energy molecule on its own.
What is the name of the coenzyme that carries high-energy hydrogens during the process of respiration?
The coenzyme that carries high-energy hydrogens during respiration is called nicotinamide adenine dinucleotide (NAD+). NAD+ accepts hydrogen atoms and becomes reduced to NADH, carrying the high-energy electrons to the electron transport chain for ATP production.
Which molecule acts as a carrier for high energy electrons during photosynthesis?
NADPH (nicotinamide adenine dinucleotide phosphate) is the molecule that acts as a carrier for high-energy electrons during photosynthesis. It is produced during the light reactions of photosynthesis and carries the electrons to the Calvin cycle to help in the synthesis of sugars.
After light hits photosystem I its energy is used to produce what molecule?
NADPH
What is the difference between NAD and NADH?
NAD (nicotinamide adenine dinucleotide) is a coenzyme that can accept or donate electrons during cellular respiration. NADH is the reduced form of NAD, meaning it has gained electrons. NADH is a high-energy molecule that carries electrons to the electron transport chain for ATP production.
